Pigeonpea [Cajanus cajan (L.) Millsp.] is traditionally cultivated as an annual crop in semi-arid regions of the world. It has a number of characteristics such as diverse maturity time, drought tolerance and natural out-crossing which makes it unique among legumes. These traits not only allow its cultivation in diverse environments and cropping systems, but also permit implementation of different breeding methods. Pigeonpea is a crop of sustainable agriculture and poor crop management, exposure to diseases and pests coupled with unpredictable rains hinder crop improvement activities. However, recently partial out-crossing has been exploited to develop cytoplasmic male-sterility (CMS) based hybrid breeding technology. Thus far, three hybrids have been released for cultivation with yield advantages of 30–50% over standard varieties. Pigeonpea R&D now also enjoys a wealth of genomics resources such as a draft genome sequence, resequencing data, candidate genes and markers associated with key traits. Genomics and breeding efforts are underway to make pigeonpea a more sustainable crop and to unlock the genetic diversity present in germplasm to develop new cultivars rapidly.
