 ABSTRACT

Twenty genotypes of common bread wheat (Triticum aestivum L.) were evaluated in 4 different environments viz., timely sown irrigated condition (E1), timely sown partially irrigated condition (E2), late sown irrigated condition (E3), and late sown partially irrigated condition (E4) to assess the stability of these genotypes for yield and its contributing traits over four environments in a randomized complete block design with two replications. Analysis of variance of stability with respect to different traits revealed that variance due to environment was highly significant for all characters except flag leaf width, which indicated the differential effect of different seasons. The variance for the genotypic effect was highly significant for all traits indicating thereby differential response of all the genotypes. The variance due to G x E interaction (linear) was highly significant for days to heading, tillers per plant, grain weight per spike, indicating a substantial amount of predictable G×E interaction. Timely sown partially irrigated condition (E2), irrigated late sown condition (E3) was found favorable for yield and its related attributes except for tillers per plant and canopy temperature. Genotypes, RVW-4272, and RVW-4278 were found stable and responsive in favorable conditions only. Based on stability parameters, genotype RVW-4271, RVW-4273, RVW-4274, RVW-4261, and RVW-4280 appeared as promising genotype and stability for grain yield for these genotypes was found associated with most of the yield attributes.
