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