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 xJ 1248,5054A XJ1623,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.
Keywords: Pennisetum typhoides, heterosis stability, grain yield.
