Abstract:
Stability for grain yield performance and genotype x environment (G x E) interaction was studied in complete set of 64 genotypes [54 hybrids, six tester, three maintainer lines and one standard check (GHB 1129) were made by using line x tester mating design] of pearl millet evaluated in a randomized block design with three replications and three environments i.e. Kharif-2020 (DOS: 18th July, 2020), Summer-2021 (DOS: 11th February, 2021) and Summer-2021 (DOS: 21st February, 2021) designated as E1, E2 and E3, respectively at the two different locations, i.e. at Instructional Farm, JAU, Junagadh and PMRS, Jamnagar during kharif-2020 and summer-2021, respectively. Among parents, J-2602 (57.16 g) and among crosses, ICMA4 11999 x J-2591, ICMA4 11999 x J-2597, ICMA5 11999 x J-2597, ICMA1 11999 x J-2597, ICMA5 11999 x J-2607 and ICMA5 11999 x J-2591 were having more grain yield per plant and had the least deviation from linear regression, but had significant regression coefficient (bi >1) and found to be highly responsive to better environments. while ICMA1 14666 x J-2565 and ICMA5 14666 x J-2565 had more grain yield per plant with non-significant deviation from regression, but had significant regression coefficient (bi < 1) showed above average response and high stability under unfavourable environments. The stable parents J-2482 were also showed stability for important yield components like ear head girth, total biomass per plant, Fe and Zn content. This indicated that stability of various component traits might be responsible for the observed stability of various hybrids for grain yield per plant. Hence, chances of selection of stable hybrids for yield could be enhanced by selecting for stability for yield components.
