COMBINING ABILITY OF SOME INBRED SUNFLOWER (H. ANNUUS L.) LINES

Abstract

The general and specific combining ability of seven inbred sunflower lines, and gene effects for kernel content, oil content in seed,and seed yield per plantwere tested. Additive and nonadditive gene effects had important function in the inheritance of all three traits. However, the genes with additive effect are predominant in the inheritance of kernel contentand oil content in seed, while geneswhich have nonadditive effect are predominant in the inheritance of seed yield per plant. The best general combiners for kernel content, oil content in seed, and seed yield/plant are the inbred lines L-3 and L-4.
