Genetic Variability and Character Association in Advance Inbred Lines of Pearl Millet Under Optimal and Drought Condition
Year: 2018
Type: article
Abstract: This study was conducted to investigate genetic variability among 50 advance inbred lines of pearl millet. The genotypeswere evaluated for 15 growth traits, yield components, and grain yield. All the quantitative traits varied significantlyamong the tested genotypes. A wide range was observed for all parameters of genetic variability for all the traits. A higherPCV for various characters than its corresponding GCV suggested the role of considerable component of environment inthe expression of all these characters. High to moderate heritability and genetic advance as per cent of mean for dry fodderyield per plant, grain yield per plant indicated that selection will be effective for further improvements. Comparativemean performance for various traits of Bawal location (drought) and Hisar location (normal) revealed that the charactersexpression at Bawal was much reduced causing significant reduction in grain yield. The correlation coefficients revealedthat estimated genotypic correlations for most of the characters were greater than their corresponding phenotypic ones.Results revealed that number of tillers per plant at Hisar location and dry fodder yield at Bawal location can be used asindirect selection criteria to increase the seed yield.
