Dry pod yield per plant showed significant correlations with kernel yield and number of branches.
High heritability was noted for traits like 100-seed weight and oil content, crucial for selective breeding.
Path analysis identified shelling as having the highest direct effect on dry pod yield in groundnut.
The study utilized a randomized block design to analyze 25 groundnut genotypes and evaluate their yield traits.
