During the laboratory and field investigation the morphological and seed quality parameters assessment for 17 vegetable pea genotypes was evaluated. The experiment was laid out in a randomized complete block design, with 17 treatments and 3 replications. Field parameters were evaluated by plant morphological characteristics viz. days to 50% germination, days to 50% flowering, plant height, pod length, pod diameter, seeds per pod and seed yield per plant. Seeds of all the genotypes were evaluated for different laboratory test, namely 100 seed weight, seed diameter, germination test, viability test, germination capacity, germination energy, germination value, speed of germination, shoot length, root length, seedling length, seedling fresh weight, seedling dry weight, first count percentage, vigour index I and II. Results from the present investigation revealed that all the seed quality parameters were significantly correlated with each other. Wide significant variation was recorded among all the genotypes during field and laboratory experiments. All the laboratory vigour traits measurements were significantly correlated with other vigour, viability components and seed yield per plant. Seed yield per plant was significantly positively correlated with viability test, seedling dry weight, speed of germination and seed vigour index II. It’s become more evident from the multiple regression analysis that vigour index II was significantly affected by vigour and viability components like viability test, germination capacity, germination value, seedling dry weight and vigour index I. On the basis of salient findings of present study, it is concluded that most of the traits like viability vigour and germination for the assessment of seed quality was recorded best for Darl-404, Darl-405, Arkel, VL-7, VP-403, Rajpura No.1. Therefore, these genotypes can be proved as the best superior genotypes or most promising genotypes as serves for the cultivation option in mid hills of Uttarakhand and can be utilized in breeding programmes for further improvement in seed quality parameters.ennullThesis
