The earliest maturing pigeonpea [Cajanus cajan (L.) Millspaugh] germplasm bred at ICRISAT
- 14 Downloads
Adaptation of pigeonpea [Cajanus cajan (L.) Millspaugh], a short-day species, is restricted due to its sensitivity to photo-period. Earliness in this crop is reported to be linearly associated with photo-insensitivity; and this provides an opportunity to breed widely adapted cultivars through the selection for earliness. This research note reports breeding of the earliest maturing pigeonpea germplasm at ICRISAT. This germplasm, nicknamed as ‘super early’ and bred through the selection of transgressive segregants matured in < 90 days. It can be used as a source material in breeding early maturing cultivars and also can be introduced for cultivation in new production niches.
