Abstract: Stability for grain yield performance and genotype x environment (G x E) interaction was studied in 45 genotypes (Nine restorer inbred and their 36 hybrids made by using half diallel mating design) of pearl millet by evaluating them in different environments [Early (3th July), timely (18th July) and late sowing (3 th August)] following randomized block design with three replications during kharif 2017 at Sagadividi Farm, Department of Seed Science and Technology, College of Agriculture, Junagadh Agricultural University, Junagadh. One parents J-2482 and Nine Crosses (J-2433 × J-2482, J-2433 × J-2496, J-2433 × J-2508, J-2479 × J-2496, J-2482 × J-2496, J-2482 × J-2507, J-2496 × J-2507, J-2496 × J-2508 and J-2507 × J-2508) expressed their stability across the environments due to their high grain yield per plant, non-significant regression coefficient (bi) and deviation from linear regression (S2di). The crosses, J-2433 × J-2503, J-2433 × J-2507, J-2479 × J-2482, J-2482 × J-2503, J-2496 × J-2503 and J-2500 × J-2507 were having more grain yield per plant and had the least deviation from linear regression, but had significant regression coefficient (bi >1) and thus, found to be highly responsive to better 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.
