Ten maize hybrids along with two checks were evaluated across three locations spread over different agro-climatic zones of Jammu and Kashmir that differ in soil type, altitude and mean annual rainfall during Kharif 2020. The experiment was laid out in a randomized complete block design with three replications. Stability parameters such as mean (X), regression coefficient (bi) and deviation from regression (S2di), as suggested by Eberhart and Russell (1966) were evaluated in order to assess the stability of these hybrids for various characters under consideration. Analysis of variance revealed that the hybrids possessed highly significant variability for all the traits under study. The mean squares due to G×E (linear) were significant for all the morphological traits viz., days to 50% tasselling, days to 50% silking, plant height, ear height, cob length, cob diameter and test weight. The mean square due to pooled deviation (non-linear) was significant for some traits like days to 50% silking, days to 50% silking, ear height, cob length and cob diameter. The mean square due to environment (E -linear) were significant for all the traits viz., days to 50% tasselling , days to 50% silking, days to maturity, plant height (cm), ear height (cm), cob length (cm), cob diameter (cm) and test weight . Based on the mean performance H05, H32 and H23 were high yielding hybrids across the locations and were average in stability while based on stability parameters the hybrids H11, PMH-10, DHM-117 were poorly adapted. The genotypes having significant and more than unit bi values were suited for better environment only for this trait.
