Pronounced grain yield heterosis with varying degree and magnitude was expressed in various individual crosses under different environments. Environment-specific as well as widely adaptable hybrids and parents were identified. The top ranking hybrids were 126D2A x J 1248, 5054A X J 1623,and 5141A X A487. The male sterile line 5054A and pollinator J 1248 were versatile for providing highly heterotic hybrids in individual as well as across the environments. Differential behaviour of heterosis under varying environments and various breeding approaches are discussed.
