Title : GxE interaction and stability performance of basmati and non-basmati rice genotypes under transplanted rice production system

Abstract :

Thirty basmati and non basmati rice genotypes were evaluated for GxE interaction and stability performance under transplanted rice production systems at RRS, Kaul, CCS HAU, Hisar, (Haryana) during Kharif season. The experiment carried out 30 genotype using Randomized Complete Block Design with three replications. Micro-environments were created by using different dates of sowing. GxE interaction and stability of genotypes for days to 50% flowering, days to maturity, plant height, panicle length, number of tillers per plant, harvest index, number of grains per panicle, biological yield per plant and grain yield per plant were analyzed by Eberhart and Russell’s method. The genotypes, environments and genotype × environment interaction components showed significant differences for most of the traits when tested against pooled deviation revealed that the selected genotypes are rich in variation and environments were different from each other and wide differential response of genotypes in changing environments. The genotype main effects, environment (linear) and the E+GxE (linear) interaction were all highly significant. Pusa basmati 1 obtained as a stable genotype for number of grains per panicle and genotypes such as HKR 12-2, HKR 11-87, HKR 07-147, HKR 11-79, IR 91648-B-59-B-1-1, IR 91648-B-2-38-B-1-2, HKR 47and HKR 48, were found suitable for grain yield for favourable environments.
