Abstract
The experimental material comprised of 16 genotypes of vegetable pea (Pisum sativum L.) including released commercial cultivars and elite lines developed from different Institutes of India. The seed samples of each genotype were subjected to laboratory testing in Complete Randomised Design for 100 seed weight (g), first count (%), standard germination (%), root length (cm), shoot length (cm), seedling length (cm), seedling fresh weight (g), seedling dry weight (g), vigour index-I and vigour index-II. With view to find out relationship of seed viability and seedling vigour parameters with field performance of the genotypes, the crops of all genotypes were raised in Randomized Block Design with three replications. The experimental crops were raised using recommended cultural operations for this region. Observations were recorded for days to 50% flowering (DAS), plant height at 50% flowering (cm), number of pods per plant, pod length (cm), pod diameter (mm), number of seeds per pod, 10 pod weight (g), pod yield per plant (g) and seed yield per plant (g). The data were analysed statically of variation in general performance for seed viability, seedling vigour and field parameters and correlation coefficients in between them. The genotype Pea-1001 registered maximum value for first count (73.66%), standard germination (92.33%), seedling fresh weight (4.07 g), seedling dry weight (0.92 g) and vigour index-II (87.09) whereas, Pea-801 emerged promising for shoot length (7.96 cm), seedling length (22.43 cm) and vigour index-I (2027.08). Maximum value for 100 seed weight was noted in VL-7 (26.03 g) whereas; VRP-7 had highest root length (14.85 cm). On the basis of field performance it was observed that P-89 was promising genotype for number of pods per plant (9.67), pod length (10.89 cm), pod yield per plant (56.58 g) and seed yield per plant (8.58 g) whereas AP-3 had maximum values for plant height at 50% flowering (67.33 cm) and number of seeds per pod (8.33). Minimum days to 50 % flowering was noted in Arkel (35.0 DAS) and CHP-2 had maximum pod diameter (13.26 mm). The genotype PM-2 registered maximum value for 10 pod weight (64.54 g). From correlation coefficients, it was evident that prior estimation of standard germination, seedling dry weight and seedling vigour index-II of the seed lot in any genotype could be used to predict the yield potentiality of that genotype in open field conditions.
