PATH ANALYSIS IN BLACK GRAM
Abstract
A study was undertaken with 183 germplasm collections. Quantitative characters such as days to 50 per cent flowering, days from flowering to maturity, days to maturity, plant height, number of pods per plant, pod length, number of seeds per pod, 100 seeds weight, harvest index, biological yield per plant and seed yield per plant were taken to understand the relationship between them. All the characters showed positive correlation with seed yield per plant. The number of seeds per pod showed the highest correlation followed by pod length and number of pods per plant with the seed yield per plant. In path analysis, biological yield per plant, harvest index and pod length showed high positive direct effect on yield and thus could be inferred as the important yield components. The residual effect was in low magnitude.
