| description | The study was undertaken to determine genetic variability of yield and its components traits in pearl millet germplasm. A set of 376 germplasm was evaluated in Augmented Block Design (ABD) without replications under irrigated conditions during summer 2017 season. Observations were recorded on 10 yield and yield contributing traits. A notable amount of variation was found in material under study. Wide range of variation, were recorded for the traits viz., days to 50 per cent flowering, plant height, number of productive tillers per plant, leaf sheath length, leaf blade length, leaf blade width, spike length, spike girth, 1000 seed weight, single plant yield. The characters viz., single plant yield, number of productive tillers per plant, spike length, leaf blade width and spike girth showed high phenotypic and genotypic coefficients of variance. Higher estimates of heritability along with high genetic advance as per cent of mean were observed for number of productive tillers per plant and leaf blade width. Therefore, selection for these characters in the given set of germplasm will be more effective. |
