Abstract: The present study was carried out to assess the nature and magnitude of genetic variability for yield and quality related traits in 76 genotypes of foxtail millet, carried at Agricultural college farm, Bapatla during kharif, 2019-2020. The analysis of variance revealed presence of significant differences for all the triats under study, indicating that the genotypes under study were genetically diverse for most of the traits. Coefficient of variation studies indicated that the estimates of GCV were lesser than the corresponding PCV values for all the traits indicating the influence of environment on expression of the characters under study. Most of the traits viz., SCMR at grain filling stage, plant height, panicle length, number of productive tillers/plant, 1000 grain weight, protein, calcium, iron, zinc, copper, manganese, antioxidant activity and grain yield per plant recorded moderate PCV and GCV. High variability and high heritability coupled with high genetic advance as per cent of mean was observed for characters viz., plant height, panicle length, number of productive tillers per plant, SCMR at grain filling stage, zinc content, copper content, iron content, manganese content, protein content, calcium content, antioxidant activity and grain yield per plant indicating the predominance of additive gene action. Hence, direct phenotypic selection may be useful with respect to these traits for further improvement in foxtail millet breeding programmes.
