Abstract

Genetics of oil content was studied in a set of 12×12 half diallel crosses of sesame which indicated importance of both dominant and additive gene action. TMV 5, Pratap and Phule Til-1 emerged as a good general combiner for high oil content. Among the crosses, B67×E8, B67×RT103, RT103×T13 exhibited positive and significant SCA effect indicating non-additive gene action for high oil content. Study of various genetic parameters revealed that just one group of genes or loci with ‘dominant’ and ‘increasing’ alleles might be involved in the synthesis of oil in seeds and involvement of modifiers in the background genotype could not be ruled out.
