Description The present experiment was carried out to assess the extent of genotype ×environment interaction for grain yield, to evaluate rice genotypes for their yield performance and stability of yield and other traits across salt affected soils in a set of 27 rice genotypes using additive main effects and multiplicative interaction (AMMI) model during 2013. The G×E effects were partitioned into four principal components (PC) and (PC 1-PC 3)
were found highly significant for all the traits. Under salt stress environments the PC 1 contributed the highest of 45 % of the total G×E interaction followed by PC2 of 28%. The genotypes Bulk 212 (3568 kg/ha), CSR 2K 232 (3439 kg/ha), Bulk 18 (3404 kg/ha), CSR 11-117 (3359 kg/ha), CSR 10M2-27 (3357 kg/ha), NDRK 11-2 (3318 kg/ha), CSR 11-121 (3255 kg/ha), NDRK 50041 (3193 kg/ha), CSR 11-143 (3174 kg/ha), CSR 27-192 (3111 kg/ha), and NDRK 50042 (2909 kg/ha) had more than the average grain yield and more than CSR 36 (2842 kg/ha) which is national check for salt stress environments. The genotypes CSR 10-M27, Bulk 212, CSR 2K 232, Bulk 18, CSR 11-117, CSR10 M2-27, NDRK 11-2, CSR 11-121, CSR 11-143 and CSR 27 -192 can be considered as the most stable in salt affected soils. The genotype Bulk 212 was found to be the highest yielding variety in most of the environments across the salt stress environments. These rice genotypes could be used for commercial cultivation in salt affected soils and also used in the further breeding programme to transfer the salt
tolerance to high yield varieties.
