Adaptation and High Yield Performance of Honglian Type Hybrid Rice in Pakistan with Desirable Agricultural Traits

Round 1

Reviewer 1 Report (Previous Reviewer 1)

Dear Authors and Editor

The article only corrects minor errors compared to the previous version. The main issues that the reviewer commented on last time were barely edited.

Here is my previous comments for the first version, and compare to the second version, no improvements were found.

 

=====================

01- This manuscript is poorly written, not meeting the minimum standards of a scientific paper. There are more personal feelings in presenting and analysing the results. This should be avoided.

 

This seems to be a test report of 3 hybrid rice strains HP1, HP2 and HP3 according to the "National Uniform Yield Trials" and "Distinctness, Uniformity and Stability"  according to the requirements of Pakistan Government; the author then upgraded and interpreted these three hybrid rice strains as ecologically suitable in Pakistan and even claimed to be "Moreover, it was considerably better, suggesting that Honglian-type  hybrid rice varieties of Pakistan is less risky under climate change and global warming conditions"

 

This manuscript seemed numerous points that need correction and revision for clear understanding.

 

02- The abstract is too long. Please rewrite. Some formats and detail of the manuscript may not be MDPI format. The title is not related to the detail of the results. Please clearly specify the highlight of this study.

 

03- The introduction is nonsense, not a scientific paper. No introduction of hybrid rice varieties in this study, their genetic and agronomic characteristics, or their origin, ...

 

What is the objective of this study? The introduction should be included 1) What is known 2) what is unknown / problem / Research GAP and 3) Hypothesis / how to solve this problem or close GAP.

 

Please more introduction about the Gap between the previous study and the importance of this study [the content in the discussion should be filtered and moved to the introduction part].

 

Please add more information in the introduction part. And indicate the objective of this study at the end of the introduction part.

 

04- The Method and material part: Too bad, too superficial and not enough information to repeat the experiments or verify.

 

- No one knows the profiles of hybrid rice strains (HP1, HP2, HP3, HP4, HP5, HP6, HLR-006, 105 WR-1906, Guard53, D-121 and KSK-13) used for this study. Please provide their full profiles such as their genetic, agronomic characteristics, and origin?  

 

- Experimental location? In-house or in-field? Scale (m2 or ha?). Time of study, detailed planting start time and harvest time.

 

- Lines 137 - 139 page 4 "A total of 104 hybrids in 2020 and 137 hybrids in 2021 (including Honglian hybrid rice and check varieties) were tested under different ecological zones of Pakistan", please detail the 104 and 137 hybrid strains that were used in this study?  Meanwhile, please specify the ecological parameters of these eco-zones; no one knows what are the ecological niches in this study. Otherwise, no one knows why (or how) the difference in ecological zones in Pakistan affected the yield performance of the experimental hybrid rice strains.

 

05- The Results and Discussion: Too bad; can't read. The structure, writing style, comparative presentation and argumentation of the author are too poor.

- Table 1 does not have information on the location, size and duration of the trial

- Table 2 is not the result of this study, these primers are collected from one or more different sources. The author does not understand that it should be in the Method Materials (or appendix) but why is the result part?

- Page 6, lines 196-197, "RRI, KSK; RRI, Dokri; PARC, KSK, Guard; Golarchi, Four Brothers Multan, Emaky Sheikhupura, CKD, DG Khan" what are they? The readers can not understand.

- The same for page 7, line 211

 

Almost results show only results (that cannot see in the figure or table), please explain the meaning of the results for clearly understood. Please try to design the results to meet the objective or related to the explanation in the text.

 

When discussed and compared with other research, how can compare directly? Please compare the meaning of the results, do not compare the results.

 

In the discussion part, please truly discuss, do not review or introduce again. (I recommend the author filter the details in the discussion part and then move to the introduction part).

 

06-The conclusions are so strange due to the objective of this study is not clear. The author's conclusion rambled, "It was also observed that under higher temperatures, the performance of Honglian type hybrid rice was stable and considerably better, which suggests that the cultivation of Honglian type hybrid rice varieties in Pakistan is less risky under the scenario of climate change and global warming due to high fertility rate. Such genetic material could be very useful as genetic resources for developing new elite breeding lines in changing ecosystems. The study will be equally beneficial to the farmers and the scientific community to strengthen the country's economy"

 

But none of the results presented in the manuscript support this claim.

 

Last but not least: This article is intended to promote the Honglian hybrid rice line, rather than as a research study that could provide the scientific community with meaningful results.

This manuscript seemed numerous points that need correction and revision for clear understanding.

Response: Thanks for very constructive comment. Firstly, different hybrids were tested under field conditions in various locations of Punjab, Pakistan on the basis of their morphological characters in the year 2019-20. From them three hybrids (HP1, HP2, HP3) were selected for further evaluation in DUS and NUYT trials on the basis of desirable traits in all over Pakistan of the designated locations of  the Government of Pakistan. At some locations the temperature was higher more than 40°C e.g. Golarchi Larkana Sindh at the time of fertility the temperature was around about 45°C. Honglian type of hybrid rice varieties performed very well in such locations due to its excellent characteristics and heat tolerance ability, that could be very useful in climatic changing environment. “Moreover, it was considerably better, suggesting that Honglian-type hybrid rice varieties can be grown in Pakistan because they are less risky under climate changes, especially by the global warming challenges.” Page No2 and Line No45-47.

Reviewer #2

The authors brought changes in their manuscript, but not as much as it required. All of my comments from the previous reviewer process are not considered. The authors should consider my comments or they should respond them.

The manuscript entitled “Adaptation and High yield performance of Honglian type hybrid rice in Pakistan with excellent agricultural traits” submitted to agriculture needs corrections and improvements. Generally, the manuscript has lack of scientific contribution and written complicated. Anyway, below are major and minor comments for the improvement of the manuscript.

 

Response: Thanks for your critical review and good comments.

1. English language revision is needed.

 

Response: Thanks for pointing the mistakes. I have carefully proofread the manuscript and correct the linguistic mistakes and all the corrections have been made in blue color.

 

2. It will be better to select key words that are not mention in the title.

Response: Thanks for the comments. I have mentioned as per instruction Line No48-49.

3. L13-14: remove the repeated work (high).

Response: Thanks for pointing the mistake. I have removed the repeated work and correct as per instruction.

 

4. L27: explain PCA. The first abbreviation should be explained. Line No30 in Abstract

Response:  As per instruction abbreviation has been rewrite in full form.

 

5. The manuscript has lack of a clear objective.

Response: The objective has been incorporated in the manuscript as per suggestion/instruction. Line No16-18 in abstract.

 

6. What is the difference between the traits in L139 and L143 (length, wide, thickness and so on).

Response:  Thanks for pointing the mistakes. Corrected as per instruction Yield is quantitative trait and all other traits are quality traits. Line 163-167.

7. The varieties selection is somehow complicated. The authors selected ten hybrid rice varieties but presented only 4 varieties in Table 1. However, 3 hybrids with 2 check varieties are compared in Table 3.

Response: On the basis of seed morphological parameters performance the three hybrids were selected from ten hybrids. Firstly, the selected hybrids were compared with one check variety in-house trials. Secondly, these hybrids were tested in all over Pakistan in different locations along with check varieties and more than 100 other hybrid rice varieties. Other varieties data has been mentioned in the table 2 line no 255-256.. Regarding table 3 only presented the summarize data of Honglian type of hybrid rice. Please see the detail information in supplementary table1 and table2..

 

8. The authors showed PCA analysis in Table 4. It is unnecessary to present the data in correlation coefficient tables too, as presented in Tables 7-8.

Response: Thanks for the comment. As per instruction the unnecessary tables 7-8 has been removed from the manuscript (Line No371-372).

 

9. The authors presented the results of PCA in Table 4 but repeated in Figures 3, 4 and 5.

Response: Thanks for the comment. The data was presented separately for more clarity of the traits, variable observations and response of each trait with respect to their positive and negative effects.

 

10. What does figure 6 shown?

Response: Thanks for the comment. This is also part of this manuscript just to show the procedure for the development of honglian hybrid rice elite plant population and also with respect to future prospects for the development of mapping populations (RILs, NILs, F2).

 

11. Citation must follow the format of journal.

Response: Thanks, as per suggestion for citation journal instructions, all citations has been uniformed followed the journal formatting requirements.

 

12. The conclusion section should be rewritten following the important points of the manuscript.

Response: Thanks for the comment. The conclusion section has been improved as per instruction (Line No.595-605.

 

13. Check the references thoroughly and unify them based on the guidance of the journal.

Response: Thanks for the comment. All the references were thoroughly checked based on the guidance of the journal.

Reviewer 2 Report (Previous Reviewer 2)

The manuscript entitled “Adaptation and High yield performance of Honglian type hybrid rice in Pakistan with excellent agricultural traits” submitted to agriculture needs corrections and improvements. Generally, the manuscript is improved but still there are several problems with this manuscript. Below are major and minor comments for the improvement of the manuscript.

1.      L39: HP3 yield was higher than over check varieties (D-121, Guard-53). How about HP1 and HP2?

2.      L40: HP1 yield (7863 kg/ha) was higher than the average over-check varieties/hybrids. How about HP2 and HP3?

3.      The text in the introduction is too long with unnecessary sentences. I recommend that the authors should shorten it with the relevant sentences and paragraphs to this work.

4.      The main objective of the study was to screening, genetic diversity, adaptation and high yield performance of honglian type hybrid rice in Pakistan. Please rephrase this sentence.

5.      “A total of 104 hybrids in 2020 and 137 hybrids in 2021 (including Honglian hybrid rice and check varieties) were tested under different ecological zones of Pakistan”. This paragraph is repeated in the L178-179.

6.      L268: Statistical significance is determination of relationships between two or more variables at level of significance of 1% and 5%. Rewrite this sentence.

7.      Where is the data for section 3.2?

8.      What does figure 6 shown?

9.      I recommend that the authors should carefully check the manuscript. Present their work clearly and concisely. Select the tables and figures which are very important and give values to their text.

Dear Reviewer and Editor of Agriculture,

The manuscript entitled “Adaptation and High yield performance of Honglian type hybrid rice in Pakistan with excellent agricultural traits” submitted to agriculture needs corrections and improvements. Generally, the manuscript is improved but still there are several problems with this manuscript. Below are major and minor comments for the improvement of the manuscript.

Response: Thanks for your good comments to help us improving the manuscript. Please see point by point corrections as per comments and instructions. All the corrections have been made in blue color.

 

1. L39: HP3 yield was higher than over check varieties (D-121, Guard-53). How about HP1 and HP2?

Response: The average yield of HP1 (8709 kg/ha) was higher than 58 hybrids and also higher than one check variety (Guard-53, 8395 kg/ha), but less than the other check variety (D-121, 9197 kg/ha). On the other hand, the yield of HP2 (8833 kg/ha) was higher than 66 hybrids and also higher than one check hybrid (Guard-53), but less than other check hybrid (D-121). It was also observed that, over all the average yield of HP1and HP2 was higher in average of 104 hybrids in the four locations (Rice Research Institute Kala Shah Kaku (RRI KSK), Pakistan Agricultural Research Council Kala Shah Kaku (PARC, KSK), Emkay Shiehupura, Chaudhry Khair Din, Dera Ghazi Khan). Among seven locations both HP1 and HP2 performed very well (yield higher than the average grand mean of all locations yield 8608 kg/ha) in NUYT test 2020 (Supplementary table 1).

2. L40: HP1 yield (7863 kg/ha) was higher than the average over-check varieties/hybrids. How about HP2 and HP3?

Response: Similarly in the year 2021 the test locations were increased the average yield of HP2 (7288 kg/ha) was higher than 25 hybrids and HP3 (7387 kg/ha) was higher than 42 hybrids. It was observed that, the yield of HP2 less than both the check hybrids (D-121(7518 kg/ha), Guard-53 (7341 kg/ha) and average yield of HP3 less than (D-121) and higher than (Guard-53). Over all HP2 and HP3 performed very well higher in average yield of 137 hybrids in the two locations (Rice Research Institute Kala Shah Kaku (RRI KSK), Pakistan Agricultural Research Council Kala Shah Kaku (PARC, KSK) IN NUYT test 2021(Supplementary table 2).

3. The text in the introduction is too long with unnecessary sentences. I recommend that the authors should shorten it with the relevant sentences and paragraphs to this work.

Response: As per instructions the unnecessary sentences and paragraphs have been removed from the introduction part (Line 116-120, Line 132-138).

4. The main objective of the study was to screening, genetic diversity, adaptation and high yield performance of honglian type hybrid rice in Pakistan. Please rephrase this sentence.

Response: As per instruction/suggestion the objective of the study has been rephrased as “The main objective of the study was to screening of Honglian type of hybrid rice on the basis of adaptability, genetic diversity and high yield performance in different locations of Pakistan (Line 159-161).

5. “A total of 104 hybrids in 2020 and 137 hybrids in 2021 (including Honglian hybrid rice and check varieties) were tested under different ecological zones of Pakistan”. This paragraph is repeated in the L178-179.

Response: As per instruction the repeated sentence/paragraph has been removed from the main manuscript from the materials and methods part (Line 178-179).

6. L268: Statistical significance is determination of relationships between two or more variables at level of significance of 1% and 5%. Rewrite this sentence.

Response: As per instruction the sentence has been revised as “Statistical significance is determination of relationships between two or more variables for the prevalence of significant variance for all studied traits that implicates the usefulness of the rice hybrids for genetics analysis at level of significance of 1% and 5%” (Line 268-271).

 

7. Where is the data for section 3.2?

Response: Dear reviewer, the detail data of molecular markers (48) has been mentioned in the separate files as a supplementary table 3.

8. What does figure 6 shown?

Response: Thanks for the comment. This figure showed the utilization frame work for increasing the resistance in crop varieties for the development and improvement of new plant populations with desirable traits through hybridization/recombination and back cross breeding method.

9. I recommend that the authors should carefully check the manuscript. Present their work clearly and concisely. Select the tables and figures which are very important and give values to their text.

Response: Dear reviewer thank you very much for your nice comments. As per suggestion/instruction the manuscript has been improved. The table No. 7 and 8 has been removed from the manuscript (Line 356,365, 402-403). In results part line 361-365 has been removed regarding table 7 to 8. In discussion part line 523-532 has been removed regarding table 7 to 8. In discussion part unnecessary lines 580-588 have been removed. Remaining tables and figures values have been mentioned in text file according to instruction/suggestion.

Dear Authors

01- This manuscript is poorly written, not meeting the minimum standards of a scientific paper. There are more personal feelings in presenting and analysing the results. This should be avoided. 

This seems to be a test report of 3 hybrid rice strains HP1, HP2 and HP3 to the "National Uniform Yield Trials" and "Distinctness, Uniformity and Stability"  according to the requirements of Pakistan Government; the author then upgraded and interpreted these three hybrid rice strains as ecologically suitable in Pakistan and even claimed to be "Moreover, it was considerably better, suggesting that Honglian-type  hybrid rice varieties of Pakistan is less risky under climate change and global warming conditions"

This manuscript seemed numerous points that need correction and revision for clear understanding. 

02- The abstract is too long. Please rewrite. Some formats and detail of the manuscript may not be MDPI format. The title is not related to the detail of the results. Please clearly specify the highlight of this study.

03- The introduction. No introduction of hybrid rice varieties in this study, their genetic and agronomic characteristics, or their origin, ... 

What is the objective of this study? The introduction should be included 1) What is known 2) what is unknown / problem / Research GAP and 3) Hypothesis / how to solve this problem or close GAP. 

Please more introduction about the Gap between the previous study and the importance of this study [the content in the discussion should be filtered and moved to the introduction part]. 

Please add more information in the introduction part. And indicate the objective of this study at the end of the introduction part. 

04- The Method and material part: Too bad, too superficial and not enough information to repeat the experiments or verify.

- No one knows the profiles of hybrid rice strains (HP1, HP2, HP3, HP4, HP5, HP6, HLR-006, 105 WR-1906, Guard53, D-121 and KSK-13) used for this study. Please provide their full profiles such as their genetic, agronomic characteristics, and origin?  

- Experimental location? In-house or in-field? Scale (m2 or ha?). Time of study, detailed planting start time and harvest time.

- Lines 137 - 139 page 4 "A total of 104 hybrids in 2020 and 137 hybrids in 2021 (including Honglian hybrid rice and check varieties) were tested under different ecological zones of Pakistan", please detail the 104 and 137 hybrid strains that were used in this study?  Meanwhile, please specify the ecological parameters of these eco-zones; no one knows what are the ecological niches in this study. Otherwise, no one knows why (or how) the difference in ecological zones in Pakistan affected the yield performance of the experimental hybrid rice strains.

05- The Results and Discussion: can't read. The structure, writing style, comparative presentation and argumentation of the author are insufficient.

- Table 1 does not have information on the location, size and duration of the trial

- Table 2 is not the result of this study, these primers are collected from one or more different sources. The author does not understand that it should be in the Method Materials (or appendix) but why is the result part?

- Page 6, lines 196-197, "RRI, KSK; RRI, Dokri; PARC, KSK, Guard; Golarchi, Four Brothers Multan, Emaky Sheikhupura, CKD, DG Khan" what are they? The readers can not understand. 

- The same for page 7, line 211

Almost results show only results (that cannot see in the figure or table), please explain the meaning of the results for clearly understood. Please try to design the results to meet the objective or related to the explanation in the text.

When discussed and compared with other research, how can compare directly? Please compare the meaning of the results, do not compare the results.

When discussed and compared with other research, how can compare directly? Please compare the meaning of the results, do not compare the results.

In the discussion part, please truly discuss, do not review or introduce again. (I recommend the author filter the details in the discussion part and then move to the introduction part).

06-The conclusions are so strange due to the objective of this study is not clear. The author's conclusion rambled, "It was also observed that under higher temperatures, the performance of Honglian type hybrid rice was stable and considerably better, which suggests that the cultivation of Honglian type hybrid rice varieties in Pakistan is less risky under the scenario of climate change and global warming due to high fertility rate. Such genetic material could be very useful as genetic resources for developing new elite breeding lines in changing ecosystems. The study will be equally beneficial to the farmers and the scientific community to strengthen the country's economy" 

But none of the results presented in the manuscript support this claim.

Best wishes.

Reviewer 3 Report

In this study, the authors have made great efforts to evaluate three hybrids (H1, H2 and H3) belonging to Honglian types via the different locations in Pakistan and also use SSR markers to study their genetic diversity. Various data were obtained and presented. However, the current paper was not well documented and organized; some parts were confusing and lack of information. Hence it needs to be critically revised and edited. The authors can find some useful comments and suggestions as below:

1. Reword the whole manuscript following the specific comments directly tracked in the pdf file

2. Must be presented the specific objective of this study at the end of the Introduction part

3. Totally revise the part of Materials and Methods (see comments in the pdf file). How did the author attain the data without the methods and protocols

4. There was no information related to the different locations where the hybrids were tested. 

5. DNA analyses must be reworded and added more information regarding the primers, and should note the polymorphic markers in Fig 2.

6. The data obtained in NUYT and DUS trials must be clarified, which were done by the authors or DUS centers, hence cited references need. 

8. Discussion should be reworded, especially subsection 4.3 must be rewritten (see comments in file). It looks like the project proposal, not a scientific paper.

9. The conclusion must be reworded and should focus on the significant results obtained in this study (see comments in file)
