| dc.description.abstract | Forty greengram genotypes were grown in a randomized block design with three replications during wet season of 1998. The data recorded on ten quantitative characters viz., days to 50 per cent flowering, days to maturity, plant height (cm), number of primary branches per plant, number of secondary branches per plant, pods per plant, pod length (am), number of seeds per pod, 100-seed weight (g) and yield per plant (g) were analysed to find out the estimates of variability, heritability (broad sense), genetic advance, correlations and path coefficients. The analysis of variance revealed highly significant differences among the genotypes for all the ten characters under study. Days to 50 per cent flowering, days to maturity, plant height and number of pods per plant showed a wide range in their gross variability. The characters, number of primary branches per plant, number of pods per plant, grain yield per plant and number of secondary branches per plant recorded high phenotypic coefficient of variation, Plant height, 100-seed weight and number of seeds per pod showed moderately high coefficient of variation. Number of secondary branches per plant, number of primary branches per plant, 100-seed weight and yield per plant recorded high genotypic coefficient of variation while plant height, number of pods per plant and days to 50 per cent flowering showed moderate coefficient of variation. Heritability (in broad sense) for the characters days to 50 per cent flowering, 100-seed weight and days to maturity were high. Number of secondary branches per plant, 100-seed weight and number of primary branches per plant showed high genetic advance as per cent of mean. Grain yield per plant was strongly correlated with number of pods per plant and number of primary branches per plant. Correlation between days to 50 per cent flowering and days to maturity was highly significant . Path coefficient analysis revealed that the character number of pods per plant had the maximum direct effect on grain yield per plant. Pod length and number of secondary branches perta plant also showed appreciable magnitude of direct effect on grain yield per plant. High correlation between grain yield per plant and pod length was also through number of pods per plant. It appears that phenotypic selection for number of pods per plant, number of secondary branches per plant and pod length would be useful for all practical purposes in greengram. | |
