Abstract:
Genotype × environment interaction in pearl millet was studied for grain yield per plant and other quantitative characters by growing 51 genotypes consisting of 36 hybrids, 13 parents along with two standard checks viz., HHB-299 and HHB-67 Improved in RBD with three replications during Kharif, 2018 at two different locations creating three environments i.e., Bajra Section, Dept. of Genetics and Plant Breeding, CCSHAU, Hisar (E₁), Dryland Agriculture, CCSHAU, Hisar (E₂) and Regional Research Station, CCSHAU, Bawal (E₃). The nature and extent of genotype × environment interactions were studied. The joint regression analysis indicated the importance of unpredictable components along with predictable components of G × E interaction. Among the crosses ICMA 04888 × A₅R-08-108, 81A₁ × H 1305, 81A₅× A₄RL/13-119, 81A₅ × H 1305, 81A₄ × A₅RL-10-203 and 81A₅ × AC 04/13 were identified as widely stable and best performing hybrids for grain yield and other quantitative characters.
