The experiment comprised of six F1’s, which were selected based on the combinations of low yield × high yield and low ASI × high ASI. The selected six F1’s were crossed in full diallel mating design to synthesis 18 three way crosses was estimated and validated on the basis of performance of their constituent single crosses. Out of 18 hybrids, TWC 3 recorded lower days to tasseling and silking and hence it can be used further in breeding programme. While, TWC 4 (0.32), TWC 11 (0.5), TWC 9 (0.76), TWC 10 (0.79), TWC 14 (0.81) and TWC 5 (0.89) recorded least ASI. Hence, it is suggested to be used in deriving superior inbreds of narrow ASI or hybrids suitable for water deficit conditions. The expected yield performance of TWC 1 (128.13) and TWC 2 (126.24) out yielded best check, Nithyashree (126.00) while, TWC 15 (125.49), TWC 17 (123.19), TWC 16 (121.92), TWC 4 (119.51) out yielded best check, Hema (119.00). All 18 three way crosses manifested significant differences between realised and predicted performance suggesting involvement of epistasis in genetic control of grain yield plant-1. By and large, there was a good agreement between realized and predicted performance of three way cross hybrids for all characters except for grain yield plant-1 and shelling percentage.
