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