Five castor bean varieties have been diallelly crossed including reciprocals. The analysis of components of genetic variability (D, H1, H2, F) for kernel and husk content in seed has been done according to Hayman (1954). Both components of genetic variability, additive (D) and dominant (H1 and H2) have been included in the genetic control of the studied characteristics, in the latter being slighly larger than the former. The value of F has been negative for kernel content and positive for husk content. The obtained value of (H1/D)**1/2 indicated that superdominance has been expressed in the inheritance of both characteristics when all combination are taken into account. High values of broad sense heritability and intermediation values of narrow sense heritability have been calculated for both characteristics.
