Description Pigeonpea [Cajanus cajan (L.) Millsp.] is an important rainfed pulse crop of tropics and sub-tropics, and
during its long growth cycle of 6–9 months it encounters a number of biotic and abiotic stresses. The recently
developed CMS-based pigeonpea hybrids have demonstrated large gains in yield and stability over the traditional
inbred cultivars. In this review, the authors argue that the heterosis expressed in traits like seed germination,
radicle growth, root biomass production and moisture retention during water stress confers advantages
to hybrid plants in negotiating a few abiotic and biotic stresses in much better way than pure line cultivars.
