Adaptability and stability of sweetpotato varieties for low-input systems in Uganda

Sixteen of sweet potato varieties were evaluated for fresh storage roots yield in 20 trials during 2000-2001 for three seasons in four locations in Uganda.Of the 16 varieties, 11 were developed by farmers and five by central breeding programme. The behaviour of the varieties was quantified in terms of wide adaptation (genotypic mean across trials), specific adaptation (genotypic prediction for specific location) and stability (Shukla stability variance). The results illustrate the potential that farmer varieties can have in the improvement of sweetpotato in Uganda and other regions where high diversity of sweetpotato landraces exists.
