Data collation and analyses were undertaken as part of the initiative “Adapting Agriculture to Climate Change: Collecting, Protecting and Preparing Crop Wild Relatives” which is supported by the Government of Norway. The project is managed by the Global Crop Diversity Trust with the Millennium Seed Bank of the Royal Botanic Gardens, Kew, UK, and implemented in partnership with national and international genebanks and plant breeding institutes around the world.","Pigeonpea [Cajanus cajan (L.) Millsp.] is a versatile, stress-tolerant, and nutritious grain legume, possessing
traits of value for enhancing the sustainability of dry sub-tropical and tropical agricultural systems.
The use of crop wild relatives (CWR) in pigeonpea breeding has been successful in providing important
resistance, quality, and breeding efficiency traits to the crop. Current breeding objectives for pigeonpea
include increasing its tolerance to abiotic stresses, including heat, cold, drought, and waterlogging. Here
we assess the potential for pigeonpea CWR to be further employed in crop improvement by compiling
wild species occurrence and ex situ conservation information, producing geographic distribution models
for the species, identifying gaps in the comprehensiveness of current germplasm collections, and using
ecogeographic information to identify CWR populations with the potential to contribute agronomic traits
of priority to breeders. The fifteen prioritized relatives of pigeonpea generally occur in South and Southeast
Asia to Australia, with the highest concentrations of species in southern India and northern Australia.
These taxa differ considerably among themselves and in comparison to the crop in their adaptations to
temperature, precipitation and edaphic conditions. We find that these wild genetic resources are broadly
under-represented in ex situ conservation systems, with 80% of species assessed as high priority for further
collecting, thus their availability to plant breeders is insufficient. We identify species and highlight
geographic locations for further collecting in order to improve the completeness of pigeonpea CWR germplasm
collections, with particular emphasis on potential traits for abiotic stress tolerance.","2015","published",,"Biological Conservation","184",,"Elsevier","ICRISAT, Lilongwe, Malawi","259-270","66","(Socioeconomics Discussion Paper Series)","ICRISAT, Lilongwe, Malawi","-","conference","10.1016/j.biocon.2015.01.032",,"International Crops Research Institute for the Semi-Arid Tropics","RP-Market Institutions and Policies",,"TRUE",,"0006-3207",,,,,,"","http://dx.doi.org/10.1016/j.biocon.2015.01.032","http://scholar.google.co.in/scholar?as_q=Crop+wild+relatives+of+pigeonpea+%5BCajanus+cajan+%28L.%29+Millsp.%5D%3A+Distributions%2C+ex+situ+conservation+status%2C+and+potential+genetic+resources+for+abiotic+stress+tolerance&as_epq=&as_oq=&as_eq=&as_occt=ti","pub",,"","",,,,,,"",,,,,,,"",,,,,"",,,,,"","",,,,,"","",,,,,
