Abstract:
An experiment was conducted with forty one genotypes in rabi season of 2019-20 at research and education farm, Department of Agriculture Botany, College of Agriculture, Dapoli. Observations were recorded on fourteen characters viz., days to initiation of flowering, day to 50 per cent flowering, days to maturity, plant height at maturity (cm ), number of primary branches per plant, number of pods per plant, number of seeds per pod, pod length 100 seed weight, dry matter yield per plant, seed yield per plant, harvest index (%), protein content (%) and iron content (ppm). A wide range of variation exhibited for yield and yield attributing traits among the progenies under study. In general PCV was higher in magnitude than GCV. The analysis of variance revealed significant variation among the genotypes for all the characters studied. The estimates of mean sum of squares showed comparatively wide range of variation for the characters Iron content, dry matter yield per plant and plant height at maturity while the lowest variation was recorded for number of primary branches per plant. Appreciable heritability values were observed for the characters under study. Highest heritability estimates were recorded for the character, iron content, dry matter yield per plant, plant height at maturity, days to initiation of flowering and days to 50% flowering. The lowest heritability estimate recorded in number of seeds per pod, pod length, hundred seed weight and number of primary branches per plant.
