An attempt has been made to assess the combining ability of castor inbred lines involving two pollen parents and a set of twelve exotic and Indian varieties as female parents, adopting line x tester analysis technique. The study revealed that the genetic variability is not predominantly additive for yield, number of branches, number of racemes. length of main raceme, length of pistillate region of raceme and total number of capsules. A large part of total genetic variation for seed yield and its components was associated with a significant general combining ability effect while specific combining ability had small effects on yield.
