Abstract: The present investigation consists of 40 genotypes of Foxtail Millet, which were grown in the Field Experimentation Centre of the Department of Genetics and Plant breeding, SHUATS, Prayagraj during Kharif 2019 following RBD with three with three replications. The data were recorded on 13 characters to study the analysis of variance, heritability, genetic advance, coefficient of variation, correlation coefficient and path analysis. Based on the mean performance genotype ISE1419, were identified as best genotypes for grain yield per plant. Highly significant variation was obtained for all characters studies. The values of PCV were higher than that of GCV for all the characters. High heritability estimates coupled with high genetic advance as percent mean were observed for Harvest index(%) followed by test weight, Grain yield, No. of basal tillers, Inflorescence width. Thus these traits are predominantly under the control of additive gene action and these Charecters can be improved by selection. Moderately high genetic advance observed for Days to 50% flowering, leaf width, flag leaf length Biological yield and No. of days to maturity. These traits appear to be under the control of both additive and non additive gene actions. The present study revealed that grain yield per plant was positively and significantly correlated with Days to 50% flowering, No. of Days to maturity, Plant height, Panicle length, Inflorescence width, Biological yield, Harvest index, Test weight. Path analysis studies revealed that Days to 50% flowering, Panicle length, Peduncle length, Biological yield, Harvest index and Test weight had true relationship with grain yield per plant by establishing significant positive association and positive direct effect at phenotypic level. Considering the nature and magnitude of character associations and direct and indirect effects, it can be inferred that days to 50% flowering, Panicle length, Peduncle length Biological yield, Harvest index and test weight could serve as important traits in any selection programme for developing high yielding foxtail millet genotypes.
