Genotype × Environment Interactions in Sorghum Variety Tests in the Sudan Central Rainlands
Published online by Cambridge University Press: 03 October 2008
Summary
Estimates of variety × environment interactions for grain yield were obtained from a study involving 16 sorghum varieties grown at the same three locations over a 3-year period. Whereas the variety × year interaction was small and not significant, the variety × location and the variety × location × year interactions were highly significant. Evidence was presented suggesting that the years of testing could be reduced by increasing the number of test locations. T.F.M.7 and Karkatib 4/1/1 were identified as desirable varieties, combining high yield and stability of performance, thereby deserving a place both in commercial production and future breeding programmes.
