Abstract


The present study aims to reveal the presence of genetic variability for yield and yield contributing traits in sixtyfinger millet genotypes. The phenotypic coefficient of variation was higher than the genotypic coefficient of variation forall the characters studied which shows the influence of the environmental effect on the characters.High phenotypiccoefficient of variation (PCV) and genotypic coefficient of variation (GCV) recorded for characters like, finger length,earhead length, seed yield per plant and straw yield per plant indicating the presence of high degree of variability and betterscope for further crop improvement. High heritability coupled with high genetic advance as per cent of mean was recordedfor plant height, number of tillers per plant, number of productive tillers per plant, finger length, number of fingers per ear,earhead length, earhead weight per plant, seed yield per plant and harvest index indicating less influence of environment onthe expression of these characters and they may be governed by additive gene action so simple selection can be practiced forimprovement of these traits
