Abstract

Seventy genotypes which includes fifty hybrids and fifteen parents along with five checks of pearl millet were studied for fifteen economically important characters to estimate variability, heritability (broad sense) and genetic advance. This study was aimed to realize the magnitude of variability among hybrids developed through crossing between inbreed lines and along with highly adaptable checks diverse origin and also to forecast the pearl millet biofortification prospects for essential micronutrients. Higher Phenotypic coefficient of variation (PCV) was observed than genotypic coefficient of variation (GCV) for all the characters under study suggesting the role of environment in the expression of these characters. High amount of genotypic coefficient of variation (GCV) for Grain yield, green fodder yield, dry fodder yield and harvest index also moderate estimates of GCV were observed for number of productive tillers per plant, plant height, panicle length, 1000 grain weight, relati
