Abstract: Grain yield potential in relation to other important agronomic characters of 1 1 vegetable pea (P. sativum L.) germplasm was tested during rabi 1999-2000. Germplasm PS-02 ranked first by producing maximum yield of 3167 kg ha-1, while germplasm PS-10 with 3056 kg ha-1 ranked second. Minimum yield of 91 1 kg ha-1 was obtained by PS-07, followed by PS-11 with 1389 kg ha-1 Average grain yield of group I was 45% higher than the average yield of group II. The average values of grain yield decreased in descending order from 2756 to 1513 kg ha-1 in group I and group II, respectively. Similarly the average values of plant height, branches per plant, dry matter yield and pods per plant decreased in descending order i.e. 1 37 to 89 cm, 2.5 to 2.2, 8490 to 3759 kg ha-1 and 1 1 to 7 in group I and group II, respectively and showed positive relationship with grain yield. The average values of pod length and harvest index increased in descending order i.e. 4.2 to 4.9 cm and 31.7 to 43.9 % in group I and group II, respectively. The relationship of days to maturity, seeds per pod and 100-seed weight with grain yield was not very well established. The association of harvest index with dry matter yield was significantly negative.
