Abstract:
An experiment entitled “Genetic variability studies for yield and yield contributing characters in pearl millet [Pennisetum glaucum (L.) R. Br.] germplasm.” was carried out during Kharif 2022-23 at the research farm of National Agricultural Research Project, Chhatrapati Sambhajinagar, Vasantrao Naik Marathwada Krishi Vidyapeeth Parbhani (M.S). The experiment was laid out in Randomized Block Design (RBD) with 32 genotypes and two replications to estimate the extent of genetic variability, heritability, genetic advance among all the genotypes. Analysis of variance showed highly significant differences among the genotypes for all the characters under study, indicated availability of wide spectrum of variability among the genotypes. The phenotypic coefficient of variation (PCV) was slightly higher than the respective genotypic coefficient of variation (GCV) for all the characters under study which indicated less influence of environment on the genotypes in expression of traits. Moderate GCV and PCV were observed for Fe content, no. of productive tillers per plant, 1000 grain weight, whereas, the lowest GCV and PCV were observed for days to maturity. High estimate of heritability along with high genetic advance as percentage of means were observed for Fe content, no. of productive tillers, 1000 grain weight indicated the role of additive gene action for expression of these characters and are prove their importance for improving seed yield. High heritability values with moderate genetic advance as percentage of means were observed for Zn content, grain yield per plot, grain yield per plant, plant height, panicle girth, green fodder yield per plot.
