Reviewer 1 Report
Overall, this paper is well written and well presented. However, I have some concerns:
- Line 219-220. ggplot is not a package to perform PCA analysis. Rewrite this sentence for clarity.
- Given the total number of accessions (174) used in this study, I was wondering why did you the simple lattice design? How many plants did you used in total? How many times the same accession occurs together in the same block?
- Lines 128-129, You should share the script used to generate field layout with Agricolae” package in R software.
What was the efficient factor?
Line 394-396 You mentioned that your results corroborate findings of other authors but you didn’t in which yam species.
I am surprised that you didn’t mention a pioneer paper on yam assessing Broad sense of heritability, genetic advance, GCV of yam traits including Harvest index DOI: 10.5897/AJB2014.14067

Reviewer 2 Report
I would recommend to include a reference (introduction, p3, line 82 and the following paragraph) to the recent study (PNAS (2020) 117:31987-31992) which investigates the relationships between D.rotundata and wild relatives D. praehensilis and D. abyssinica by genome re-sequencing. This may have been published after the authors finished working on the present manuscript.
