To study the nature and magnitude of gene effects for yield and its components in sesame (Sesamum indicum L.) we carried out generation mean analysis using the following five crosses of different sesame cultivars: TKG-503 X GT-10; RT-373 X GT-2; JLS-613-1-1 X GT-10; MT-10 X GT-2 and AT-253 X TKG-22. The P1, P2, F1, F2, and F3 of these generations were studied for twelve quantitative traits. | Generation means analysis for quantitative traits in sesame Sesamum indicum L.
