Genetic variability studies for pod yield and component traits in groundnut
Genetic variability studies for pod yield and component traits in groundnut were carried out for 40 accessions for 13 characters. The analysis of variance revealed the existence of significant differences among the genotypes for all the traits studied. The genotypes viz.,K-6, K-1696, TCGS-1157 and Dharani showed high mean performance for pod yield and its component traits viz., number of primary branches per plant, hundred seed weight (g) and kernel yield per plant (g).High heritability coupled with high genetic advance as per cent of mean was recorded by kernel yield per plant, hundred seed weight, pod yield per plant, number of primary branches per plant, number of pods per plant, shelling percent, harvest index, plant height and number of seeds per pod indicating that these characters are under additive genetic control and selection of these traits for improvement will be worthwhile and may rapidly contribute to increased pod yield in groundnut cultivars.
