Compared to the cereals and vegetable crops, cytoplasmic male sterility is comparatively a new system available topigeonpea breeders to exploit heterosis/hybrid vigor. It has been possible to develop a CMS system for pigeonpea as crosspollination is possible in this crop. Various CMS systems have been developed for pigeonpea utilizing different wildrelatives from different gene pools. CMS based hybrids developed from A4 system have recorded superiority in yieldscompared to the checks on farmer’s fields. This has opened up a new window for yield improvement in pigeonpea. Thepaper discusses different CMS systems available for pigeonpea in general and the A7 system which was developed utilizingCajanus platycarpus, in particular.
