Genotype and Environment Interaction for yield performance of 12 Advanced Tongil rice genotypes with Doubled Haploid Background under Salts tress conditions in Tanzania

Rice (Oryza sativa L.) is an important global food commodity crop. Its yield was affected by genotype, environment, and the interaction between genotype environment that demands development of diverse tolerant rice to increase yields adaptation. Genotype Environment for Tongil types with doubled haploid (DH) were evaluated in three locations. A randomized complete block design replicated times used. The additive main effects multiplicative (AMMI) analysis on grain revealed genotypes Tong rt5 rt 10 stable compared check SATO 1. rt7 performed poorly. Magozi had highest mean while Chanzuru lowest yield. Genotypes Saline-Sodic resulted different performances. Significant differences observed Differences contributed difference sum squares Scatter plot indicated positive correlation Magozi. shorter lines genotypes. experiment two Mega-Environment, share a single mega-environment. Small circle greater stability performance genotype. Performance allowed selection superior recommendation. Key words: AMMI analysis, interaction, tongil rice,
