- The morphological marker like auricle and ligule colour is important traits useful for varietal profiling and other genetic studies. This research was aimed at analysis of genetic of the auricle and ligule colour in the F1 and segregating generations (F2 and F3) of 06 crosses,IC-548384 × Chandrahasini, IC-390376 × Chandrahasini, IC-390376 × Samleshwari, IC-134022 × Durgeshwari, IC-388728 × Chandrahasini, IC-389860 × Samleshwari.Results revealed that the inheritance of auricle colour shown duplicate epistasis 15(Green): 1Purple ratio), controlled by two major genes. Whereas, inheritance of ligule colour was recorded to have digenic complementary interaction (9:7 ratio) across the studied family.
