Abstract: Grain yield potential in relation to other important agronomic characters of 13 graypea (Pisum arvense L.) germplasm during rabbi 1999-2000 was investigated in order to identify the high yielding promising germ plasm for further studies. Germplasm GP-01 ranked first by producing maximum yield of 1000 kg/ha, while germplasm GP-12 with 9444 kg/ha ranked second. Minimum yield of 49 kg/ha was obtained by GP-09, followed by GP-02 with 67 kg/ha. The germplasm in group 1 viz. GP-01 and GP-12 gave 63 and 93% higher yield than group II and group III, respectively. The higher yield in the germplasm of group I, was mainly due to more branches and pods per plant, pod length and seeds per pod and maximum dry matter than the germplasm of group II and III. GP-01 and GP-12 are the most promising germplasm recommended for further investigation.
