Yield Stability and Adaptability of Elite Doubled Haploid (DH) Rice Genotypes in Different Locations in Central Clay Plains of the Sudan

Stability analysis of grain yield is an efficient tool for the selection varieties adapted to fairly wide cultivation zone. A study aims determine adaptability and stability agronomic performance 10 elite Doubled Haploid (DH) rice genotypes generated through another culture technique, along with local cultivar Umgar as a check under irrigated lowland conditions in three different environments central clay plains Sudan; during two cropping seasons 2019 2020. The trials were conducted randomized complete block design replications. Grain was studied, using Additive Main effect Multiplicative Interaction (AMMI) model. Bi-plots developed following GGE bi-plot methodology over six environments. combined variance revealed significant highly (P MI indicated genotypes, environments, GE interaction total variation 43.16%, 44.26% 12.58% respectively. biplot-AMMI index incorporating AMMI value single non-parametric used identify highest stable yield. overall mean 5.69 t/ha, range 5.77 4.12 t/ha. k150147, k150870, k150032, k150912, k150307 out yielded by 40%, 38%, 34%, 34% 33% most mid-early maturities which harvested at 107, 113, 108, 109 112 days after sowing, These five also showed their high according widely adaptable tested locations. Therefore, yielding will be considered system condition Sudan.
