V. Muell var. grandifolius, a wild relative of pigeonpea (Cajanus cajan (L.) Millsp.). The plants of this male-sterility system do not produce pollen grains and the androecium is underdeveloped. The paper also reports identification of six diverse male-sterility maintainers. %T A novel source of CMS in pigeonpea derived from Cajanus reticulatus
