The yield characters recorded a very low heritability. However, the selection of seednuts increased the heritability from .05 to 0.25 in the case of number of nuts and 0.08 to 0.29 in the case of weight of nuts. The other morphological characters exception height and Bomber of leaves showed increased heritability due to seednut selection. The impact of seed nut selection on yield was further established by the high genotypic and phenotypic correlations for the yield characters with seed weight, seedling girth and age at 1st flowering thereby highlighting the importance of seednut selection.enarecanutbreedingArticle
