Fertility restoration of CMS-based hybrids is an integral part of breeding hybrids and the development of new hybrid parents with desirable agronomic and market preferred traits on regular intervals is essential for sustainability of such programs. This paper reports identification of 25 male-sterility maintainers and 179 fertility restorers of A4 cytoplasm in pigeonpea (Cajanus cajan (L.) Millsp.). Multi-location evaluation of hybrids exhibited high stability for fertility restoration across diverse environments. The diversity study showed a large variation for important traits both at phenotypic as well as genetic levels. The potential use of this information in hybrid pigeonpea breeding has been discussed.
