The present investigation was undertaken with the objective to study correlation and path analysis among the population consisting of eight parents and twelve F2’s of pigeon pea genotypes. Positive and significant associations were recorded between yield and yield contributing characters viz., days to maturity, 100 seed weight and pods per plant. The study indicated that the days to maturity, 100 seed weight and numbers of pods per plant should be given maximum weightage while making selections to improve the yield. Path analysis at phenotpic levels revealed that number of pods per plant and plant height had greater direct effects on seed yield, while the number of primary branches and days to maturity had direct effects on seed yield at genotypic level.

Abstract


The present investigation was undertaken with the objective to study correlation and path analysis among the population consisting of eight parents and twelve F2’s of pigeon pea genotypes. Positive and significant associations were recorded between yield and yield contributing characters viz., days to maturity, 100 seed weight and pods per plant. The study indicated that the days to maturity, 100 seed weight and numbers of pods per plant should be given maximum weightage while making selections to improve the yield. Path analysis at phenotpic levels revealed that number of pods per plant and plant height had greater direct effects on seed yield, while the number of primary branches and days to maturity had direct effects on seed yield at genotypic level.
