Abstract

Thirty six castor genotypes were evaluated for gentic parameters. Moderate to high heritability coupled with high genetic advance was noticed for single plant yield. plant height, 100 seed weight, length of primary raceme and racemes per plant attributed due to additive genes. The correlation Co-efficient and path analysis revealed that length of primary raceme, capsules in primary receme, racemes per plant and 100 seed weight were the major yield contributing characters.

Keywords: Castor, Variability, Correlation, Path co-efficients
