Abstract:
The present investigation was carried out at Agricultural Research Station, Perumallapalle, Tirupati, A.P. with 10 maintainer (B) and 27 restorer (R) lines of pearl millet during summer, 2020 in randomized block design with three replications to estimate genetic parameters viz., genetic variance, heritability (broad sense) and genetic advance as per cent of mean for 15 quantitative traits. The analysis of variance revealed highly significant differences among the genotypes for all the characters studied. The phenotypic coefficient of variation (PCV) was higher than genotypic coefficient of variation (GCV) and the difference between PCV and GCV was narrow for most of the characters, implying little influence of environment on expression of the traits. High values of PCV, GCV and heritability estimates coupled with maximum genetic advance over mean were obtained for panicle length, green fodder yield per plant, dry fodder yield per plant, panicle weight, 1000 grain weight, harvest index and grain yield per plant indicating the preponderance of additive gene action and selection based on these characters could be effective.
