Abstract

Forty finger millet genotypes were examined for eleven quantitative traits viz., days to 50% flowering, plant height, fodder yield plot-1, days to maturity, main ear length, productive tillers/plant, dry fodder yield per plot, number of fingers per ear, thousand grain weight, harvest index and grain yield per plot to estimate variability parameters. Analysis of variance revealed that significant differences for all studied characters. Grain yield plot-1, fodder yield plot-1, dry fodder plot-1 and thousand grain weight recorded high GCV, PCV, genetic advance as per cent of mean (GAM) and heritability implying that more variation and prevalence of additive gene action for these characters.

Keywords

GCV, PCV, Genetic advance, Heritability, GAM

Conclusion

Grain yield plot-1 recorded high PCV and GCV implying that greater variation present in the population for this character, providing huge scope for further improvement of this trait among the studied genotypes. High heritability merged with genetic advance as per cent of mean recorded for grain yield plot-1 indicating selection would be effective based on this character. Other characters viz., fodder yield plot-1, dry fodder plot-1 and thousand grain weight also recorded high GCV, PCV, heritability and genetic advance as per cent of mean implying that more variation and prevalence of additive gene action for these characters. Thus, selection of genotypes based on these traits will be rewarding in future breeding programmes.
