Abstract

<abstract abstract-type="main" id="pbr12045-abs-0001"> <title>Abstract</title> <p>ICRISAT scientists, working with Indian programme counterparts, developed the world's first cytoplasmic‐nuclear male sterility (CMS)‐based commercial hybrid in a food legume, the pigeonpea [<italic>Cajanus cajan</italic> (L.) Millsp.]. The CMS, in combination with natural outcrossing of the crop, was used to develop viable hybrid breeding technology. Hybrid ICPH 2671 recorded 47% superiority for grain yield over the control variety 'Maruti' in multilocation on‐station testing for 4 years. In the on‐farm trials conducted 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 <italic>Fusarium</italic> wilt and sterility mosaic diseases. The outstanding performance of this hybrid has led to its release for cultivation in India by both a private seed company (as 'Pushkal') and a public sector university (as 'RV ICPH 2671'). Recent developments in hybrid breeding technology and high yield advantages realized in farmers' fields have given hope for a breakthrough in pigeonpea productivity.</p> </abstract>
