Results of the study indicated that in gene pool days to flowering, maturity and pod length were negatively correlated with seed yield/plant and pods/plant showed positive association with seed yield/plant. In erect plant type group seed yield/plant was found to have negative association with days to maturity and pod length. Pods/plant showed positive association with seed yield/plant and negative with ODAP [b-N-oxalyl L-a,b diaminopropionic acid] content (Neurotoxin). In spreading plant type days to flowering, maturity and pod length showed negative correlation with seed yield/plant. In green plant type group days to flowering and maturity showed negative association with seed yield/plant and ODAP content. In pigmented plant colour days to flowering and maturity showed negative association with seed yield/plant. Pods/plant showed positive association with seed yield/plant in the same group. In narrow leaf type group, seed yield/plant was positively correlated with branches/plant, pods/plant and seed/pod whereas, it has negative correlation with days to flowering and maturity. Hence, selection of narrow leaf plants for early maturity, more branching, more number of seeds/pod and more number of pods/plant would lead to the development of plant possessing higher seed yield/plant. Similarly, direct selection for high-seed yield/plant would lead to the development of low toxic plant in grass pea
