ICPH 2671 – the world's first commercial food legume hybrid uri icon

abstract

  • ICRISAT scientists, working with Indian programme counterparts, developedthe world?s first cytoplasmic-nuclear male sterility (CMS)-basedcommercial hybrid in a food legume, the pigeonpea (Cajanus cajan (L.)Millsp.). The CMS, in combination with natural outcrossing of the crop,was used to develop viable hybrid breeding technology. Hybrid ICPH2671 recorded 47% superiority for grain yield over the control variety?Maruti? in multilocation on-station testing for 4 years. In the on-farm trialsconducted in five Indian states, mean yield of this hybrid (1396 kg/ha) was 46.5% greater than that of the popular cv. ?Maruti? (953 kg/ha).Hybrid ICPH 2671 also exhibited high levels of resistance to Fusariumwilt and sterility mosaic diseases. The outstanding performance of thishybrid has led to its release for cultivation in India by both a privateseed company (as ?Pushkal?) and a public sector university (as ?RVICPH 2671?). Recent developments in hybrid breeding technology andhigh yield advantages realized in farmers? fields have given hope for abreakthrough in pigeonpea productivity
