Abstract

An experiment consisting 43 diverse genotypes of table pea derived from 10 lines and 3 testers (13 parents + 30 F1s) were evaluated in a randomized block design replicated thrice at Vegetable Research Farm of C. S. Azad University of Ag. & Tech., Kanpur, (U.P.) during Rabi of 2020-21. The data were collected on days to 50% per cent flowering, node number of first flower, inter-nodal length, number of primary branches, days to first picking of pods, average pod length, number of pods per plant, average pod weight, number of seeds per pod, average plant height, seed shell per cent, green pod yield per plant. The result showed high level of genetic variability both for genotypic and phenotypic coefficients. Highest PCV and GCV was noted for plant height followed by number of primary branches, number of pods per plant and average pod weight and green pod yield per plant based on F1 while it was lowest for seed shell per cent, days to first picking of pods, average pod length and days to 50% flowering. High heritability in broad sense was noted for all the characters. The genetic advance was high for plant height, days to 50% flowering, number of pods per plant and days to first picking of pods, the highest genetic gain in the tune of 73.10% for plant height followed by number of primary branches (48.89%) and average pod weight (48.45%) and number of pods per plant (48.11%) at 5% selection intensity over mean. Simple selection procedure followed by pedigree method will be more appropriate for improving the green pod yield while making selection.

Conclusion

From this study it can be generally indicated that there was plenty of genetic variability among the genotypes. Thus, there is vast opportunity in the improvement these table pea genotypes. Therefore, the results and information generated from current study need to be used by interested plant breeders. Studies revealed that the green pod yield per plant, Average pod weight and number of pods per plant with high heritability and high genetic advance were the major yield attributing characters so emphasis should be given for these characters at the time of simple selection.
