Abstract

Direct selection for yield is misleading because of complex nature of trait and due to varied influence of environment. Indirect selection through yield contributing traits can greatly enhance efficiency of plant breeding. During post rainy (2019-20), thirty-six elite groundnut genotypes were evaluated in alfa lattice design for different genetic parameters. The observations were recorded on days to 50 % flowering, days to maturity, fresh pod yield per plant, dry pod yield per plant, hundred seed weight and shelling percentage. The analysis of variance revealed significant differences among the selected genotypes for all the traits under study at 0.01 probability levels indicate significant variability among the genotypes evaluated. Dry pod yield per plant and fresh pod yield per plant reported higher GCV and PCV estimates. High heritability coupled with high genetic advance were reported for fresh pod yield per pant, dry pod yield per plant and hundred seed weight. Dry pod yield per plant showed significant and positive connection with fresh pod yield per plant and hundred seed weight and significant negative association with shelling percentage. Path coefficient analysis revealed that traits such as fresh pod yield per plant, shelling percentage and hundred seed weight exhibited high direct effect on dry pod yield per plant indicating true and perfect relationship between them.

Conclusion

Direct selection for yield is not possible because yield is complex trait and which were affected by environmental effect in great extent. Yield can be enhanced by indirect selection of traits which are linked to traits. Dry pod yield per plant showed significant and positive association with fresh pod yield per plant and hundred seed weight and significant negative association with shelling percentage. Path coefficient analysis reveal that traits such as fresh pod yield per plant, shelling percentage and hundred seed weight exhibited high direct effect on dry pod yield per plant indicating true and perfect relationship between them.
