The present investigation was carried out at Eastern Block of the Central Farm Unit, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India to identify the gene interaction for yield contributing characters to increase the yield. For this purpose twelve biometrical characters of fifteen SDM resistant progenies viz., UMI 79/936-C1-3-2 ,UMI 79/936-C1-3-4,UMI 79/936-C1-7-2, UMI 79/936-C1-7-7, UMI 79/936-C1-29-8, UMI 79/936-C1-29-9, UMI 79/936-C1-29-13, UMI 79/936-C1-29-23, UMI 79/936-C1-29-35, UMI 79/936-C1-29-36, UMI 79/936-C1-67-3, UMI 79/936-C1-67-12, UMI 79/936-C1-67-25, UMI 79/936-C1-101-12 and UMI 79/936-C1-101-14 were used for frequency distribution studies. Analysis of skewness and kurtosis revealed that, the selected progenies for resistant to SDM showed positive skewness and negative kurtosis for most of the traits under study viz., 50% tasseling, days to 50% silking, days to maturity, plant height cob length, cob diameter, 100 grain weight and grain yield per plant. Indicating that, these characters were governed by complementary gene action was and the gain is slower with mild selection but is faster with intensive selection.
