Abstract

The experimental material consists of seventy genotypes with four checks of proso millet germplasms which were collected from NBPGR New Delhi and IIMR, Hyderabad. The experiment was laid out in Randomized Block Design with two replications during late rabi 2022. Observations were recorded on nine yield and yield contributing characters i.e. days to 50 per cent flowering, days to maturity, productive tillers per plant, plant height (cm), ear head length (cm), grain yield per plant (g), 1000 grain weight (g), fodder yield per plant (g) and protein content (%). The analysis of variance showed highly significant differences among the genotypes for all characters under study. The estimates of genotypic coefficient of variation (GCV) were lower than phenotypic coefficient of variation (PCV) for all the characters under study. The GCV and PCV both were observed to be high for productive tillers per plant, fodder yield per plant, grain yield per plant and 1000 grain weight. The character 1000 grain weight showed highest heritability followed by days to 50 per cent flowering, protein content, productive tillers per plant, days to maturity, grain yield per plant and fodder yield per plant respectively. The character fodder yield per plant showed highest genetic advance followed by plant height and days to 50 per cent flowering.

Conclusion

Wide range of variation was observed for all the nine characters under study. The analysis of variance exhibited significant difference among the genotypes for all the characters. Estimates for the genotypic coefficients of variation (GCV) were lower than the phenotypic coefficient of variation (PCV) for all the characters. High heritability estimates along with high genetic advance were obtained for several characters. The character 1000 grain weight showed highest heritability followed by days to 50 per cent flowering, protein content, productive tillers per plant, days to maturity, grain yield per plant and fodder yield per plant. The character fodder yield per plant showed highest genetic advance followed by plant height and days to 50 per cent flowering.
