Abstract:
Fifty green gram genotypes were evaluated for 10 quantitative characters viz., days to 50% flowering, days to maturity, plant height (cm), number of primary branches per plant, number of clusters per plant, number of pods per plant, pod length (cm), number of seeds per pod, 100 seed weight (g) and seed yield per plant (g). The correlation and path analysis was done to study the character association and to understand the direct and indirect effects of different characters on seed yield per plant. The correlation analysis revealed that seed yield per plant exhibited significant and positive correlation with 100 seed weight, number of clusters per plant, pod length, plant height, number of pods per plant and number of seeds per pod at both genotypic and phenotypic levels. Hence, selection for characters can improve yield in green gram. Path analysis revealed the 100 seed weight and days to maturity recorded positive and high direct effect towards seed yield per plant, moderate direct effect was observed for number of clusters per plant and low direct effect on yield was recorded by number of pods per plant and pant height. The direct effect of the remaining characters on seed yield was negligible. Thus 100 seed weight had a highly significant and positive correlation with seed yield per plant and its direct effect on yield per plant was high, selection for this character should be given emphasis in breeding programmes for yield improvement yield in green gram.
