Character association and path analysis for yield attributes in full sib progenies in pigeonpea (Cajanus cajan (L.) Mill sp.).

The estimates of nature and magnitude of association of seed yield with other components and their direct effects on seed yield were studied in Pigeonpea. Character association studies indicated that branches per plant, clusters per plant, pods per plant, pod length, seeds per pod and 100 seed weight were strongly associated with seed yield. Path coefficient analysis revealed that 100 seed weight, days to maturity, days to 50 per cent flowering, pod length and seeds per pod had high positive direct effect on seed yield. It is inferred that for improving seed yield in pigeonpea, due emphasis should be given on characters viz., branches per plant, clusters per plant, pods per plant, seeds per plant and 100 seed weight.
