Character Association and Path Coefficient Analysis for Yield Components in Pigeonpea, Cajanus cajan L.

摘要

The study was undertaken to estimate correlations and to partition these into direct and indirect contributions of different component characters towards seed yield in pigeonpea from the data recorded on 30 diverse genotypes. Observations were recorded on seed yield per plant, plant height, days to flower, primary branches per plant, pods per plant, seeds per pod, 100 seed weight and harvest index. Positive association of seed yield was observed with plant height, branches per plant, pods per plant and harvest index. Path coefficient analysis revealed that branches per plant had maximum positive direct effect followed by pods per plant and seeds per pod upon seed yield per plant. Branches per plant and pods per plant also contributed indirectly viaeach other. It was concluded that seed yield in pigeonpea may be improved by selection of tall plants having more branches and pods per plant in the segregating populations.
