Abstract

Genotype x environment interaction in pearl millet [Pennisetum glaucum (L.) R.Br.] was studied for grain yield by growing 57 genotypes consisting of 54 hybrids along with three standard checks in RBD with three replications under three different environments created by different irrigation numbers (E1, E2 and E3) with recommended dose of fertilizers during Kharif, 2015 at Agriculture Research Station farm, ARS Beechhwal, Bikaner. The nature and extent of genotype (g) x environment (e) interactions were studied. The joint regression analysis indicated the importance of unpredictable components along with predictable components of G x E interaction. Among the crosses RMS 6A x BIB-27 and ICMA 04999 x BIB-15 had higher grain yield per plant and showed stability for better management conditions and poor management conditions, respectively.
