    Evaluation of hybrids for stability of grain yield and its attributing traits in pearl millet (Pennisetum glaucum L. R. Br.)
    (CCSHAU, 2006) Abhay Bikash; Yadav, I.S.
    An experiment was conducted to study the stability, correlation and path coefficient for 11 traits in 30 hybrids of pearl millet at four locations. Significant genotypic differences were observed for all the traits in all the four environments. Estimates of environment index revealed that E1 (irrigated condition at Hisar) was the most favourable environment for majority of the characters. The G x E interaction was highly significant for all the characters and its partitioning into linear and non linear component revealed preponderance of linear component for almost all the characters except ear girth and total tillers per plant where non linear component was dominant. The estimates of stability parameters of individual genotype revealed that hybrid 97111A x CSSC46-2 was the most ideal hybrid. Besides high grain yield, it exhibited stable performance across the environments for harvest index, plant height and ear length. Correlation study revealed that grain yield was significantly and positively correlated with harvest index, ear girth, effective tillers, dry fodder yield and biological yield in all the four environments. The path coefficient analysis suggested the importance of biological yield as it has direct positive effect and indirect effect on grain yield in all four environments. Hence, while breeding for increased grain yield main emphasis should be given on biological yield.
