Abstract

Groundnut lines differed significantly for podding index and nine other traits. Correlation study showed not significant correlation between podding index and yield per plot. However, days to first 10 per cent flowering and days to last 10 per cent flowering, the difference between which measures the podding index were negatively correlated with yield per plot. Correlation of these two traits was positive with number of pods per plant. Between these two traits there was negative correlation. Days to 75 per cent flowering, 100-kernel weight, 100-pod weight, shelling per cent and number of pods per plant showed positive and significant correlation with yield per plant. Path analysis revealed that podding index and the two traits that measure it, along with 100 kernel weight and number of pods per plant had positive direct effect on yield per plot and days to last 10 per cent flowering showed the highest positive direct effect on yield per plot. Days to 75 per cent flowering and shelling per cent which were positively correlated with yield per plot showed negative direct effect or. yield. The overall result suggests that podding index or days to last 10 per flowering can be manipulated by plant breeders using restricted selection index for improving yield in groundnut.
