ABSTRACT

100 groundnut germplasm accessions were evaluated for plant height, pod yield, SCMR, late leaf spot, rust, jassids and thrips incidence. GCV and PCV values were high for pod yield per plant, late leaf spot, rust, jassids and thrips damage. High heritability estimates were recorded for all the characters ranging from 66.89% (SCMR) to 96.11% (plant height). High heritability along with high GAM for almost all the characters studied indicated the importance of additive gene action in the inheritance of these characters, hence phenotypic selection would be effective for improvement of these characters.
