Genetic variability of grain iron, zinc, yield and its contributing traits in pearl millet were studied in 30 genotypes (R-line). An experiment was carried out during Kharif-2018 at the Research Farm of ICAR-AICRP on Pearl Millet, Project Coordinating Unit, Mandor, Jodhpur. Analysis of variance showed high significant variance among the genotypes for all the characters, under study, indicated availability of wide spectrum of variability among the genotypes. Highest magnitudes of PCV and GCV were observed for zinc content whereas, the lowest for days to maturity. High estimate of heritability along with high genetic advance as percentage of mean were observed for days to 50% flowering, plant height, number of productive tiller per plant, panicle length, panicle diameter, stover yield per plant, grain yield per plant, 1000 grain weight, harvest index, iron content and zinc content suggested additive gene action for expression of these characters. Hence, these characters may be proved as effective criteria for selection to improve seed yield in pearl millet whereas high heritability values with moderate genetic advance as percentage of mean were observed for days to maturity and protein content.
