| dc.description.abstract | An experiment entitled “Variability Analysis for Morphological Traits in Pearl Millet [Pennisetum glaucum (L.) R. Br.] Under Normal and Limited Moisture Conditionsˮ was conducted with 30 genotypes in Kharif, 2020 at Research Farm of ICAR-AICRP on Pearl Millet, Project Coordinating Unit, Mandor-Jodhpur (Rajasthan). The experiment was laid out in Randomized Block Design with 3 replications in two moisture conditions and observations of days to 50% flowering, days to maturity, leaf area, flag leaf area, plant height, panicle length, panicle girth, stem girth, number of productive tillers per plant, number of nodes per plant, 1000- grain weight, dry fodder yield per plant, relative water content, chlorophyll content, grain yield and drought susceptibility index were recorded. Analysis of variance depicted significant difference for all the traits under study, indicated that good amount of inherent variations are present. The phenotypic coefficient of variance was higher than genotypic coefficient of variance for all the traits under study, indicating influence of environment on expression of such traits. The highest value of PCV and GCV were observed for dry fodder yield per plant and the lowest for days to maturity in both moisture conditions. All the traits showed high heritability except days to 50% flowering, days to maturity in limited moisture condition and RWC in both moisture conditions. High heritability coupled with high genetic advance as per cent of mean was observed for grain yield, dry fodder yield, plant height, panicle length, panicle girth, stem girth, leaf area, flag leaf area, number of productive tillers per plant, number or nodes per plant, 1000 grain weight and chlorophyll content in both moisture conditions, indicating these traits were govern by additive gene action. Hence, for the improvement in grain yield, selection on these traits could be practiced. Analysis of correlation coefficient revealed that grain yield per plant had positive and significant correlation with flag leaf area, number of productive tillers per plant, 1000- grain weight, RWC and chlorophyll content in both moisture conditions. Moreover, in normal moisture condition panicle girth and dry fodder yield per plant also showed positive and significant correlation with grain yield per plant. These results illustrating that these traits important in contribution for grain yield. High variations were observed for drought susceptibility index (DSI) in this study. DSI values ranged between 0.350 and 1.376. The genotypes with low DSI value were considered as drought resistant, meanwhile, genotypes with high DSI value were considered as drought susceptible. | |
