Abstract:

In total of 113 genotypes including three check varieties, a wide range of variability for different characters had been observed and comparison of means of genotypes using least significant differences, indicated existence of very high degree of variability for all the characters in the germplasm collection. The following five genotypes exhibited high mean performance for seed yield/plant were IP-2K-84, EC-356166, HUDP-27, DMR-15, IPFD-2-6. Seed yield per plant exhibited highly significant and positive correlation with 100 seed weight (0.3775), number of pods/plant (0.3524), harvest index (0.3270), number of seeds/pod (0.3262) and biological yield (g) (0.2828). The occurrence of negative as well as positive indirect effects on yield by one or another character presents a complex situation where a compromise balance is required to attain proper balance of different yield components, for determining the ideotype of seed yield in field pea. The highest positive direct effect on seed yield per plant was exerted by harvest index (0.7902) followed by biological yield (g) (0.7820), 100 seed weight (0.3406), number of seeds per pod (0.2788) and number of pods per plant (0.2622).
