Poster: Validating Heterosis in Sweetpotato Breeding

Why developing hybrid breeding populations?Sweetpotato is a highly heterozygous clone hybrid crop and with hybrid breeding populations we achieve (i) yield increase, (ii) ease to stack simple inherited traits such as quality and disease resistance, and (iii) elevated yield stability. Achieving these goals is much more effective by offspring-parent analysis …
