“…They take advantage of their strategic positioning in the agriculture sector to source seed of grain legumes and supply them to research institutions or farmers. Farmers have also been reported to purchase hybrid seed, which is the product (first-generation progeny) of a cross between two unrelated (genetic dissimilar) parents [78], and then recycle it similarly to how they recycle landraces [73,75]. However, unlike for landraces and other open-pollinated varieties, recycling hybrid seeds has negative implications on subsequent seed quality.…”

Expounding the Value of Grain Legumes in the Semi- and Arid Tropics

Approximately 70% of the population in the semi-and arid tropics reside in rural areas and depend on agriculture for their livelihood. Crop production is primarily focused on a few starchy staple crops. While this can ensure adequate calories, it inadvertently neglects the need for dietary diversity. Consequently, food and nutritional insecurity remains prevalent in the semi-and arid tropics. We reviewed the legume value chain with the aim to identify opportunities and challenges to unlocking their value and promoting them in the tropics. Several grain legumes are rich in proteins and micronutrients. They also possess adaptability to marginal environmental conditions such as drought and low input systems which typify rural landscapes. Adaptability to abiotic stresses such as drought makes them key to agriculture in areas that will receive less rainfall in the future. However, this potential was currently not being realized due to a range of challenges. Aspects related to their seed systems, production, post-harvest handling and marketing remain relatively under-researched. This was especially true for minor legumes. There is a need for transdisciplinary research which will address the entire value chain, as has been done for major starchy crops. This could also unlock significant economic opportunities for marginalized groups such as women. This will unlock their value and allow them to contribute meaningfully to food and nutrition security as well as sustainable and resilient cropping systems.

“…Concerted breeding efforts for this purpose have resulted in a number of promising advances, particularly the creation of early maturing varieties, and developments toward diverse high yielding hybrids (Saxena, 2005;Saxena et al, 2013;Saxena and Sawargaonkar, 2014). However, crop yield in most production regions is well below its potential and has been stagnant for a number of decades, with increased production during this time largely due to an expansion of harvested area (Saxena, 2005;Odeny, 2007;Jones et al, 2002).…”

a b s t r a c tPigeonpea [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.

“…sources only two, C. scarabaeoides (A 2 ) (Tikka et al, 1997) and C. Cajanifoliuos (A 4 ) (Saxena et al, 2005) were successfully used to develop stable CGMS systems in pigeonpea. Through the CGMS system, three hybrids [GTH-1 (Acharya et al, 2008), ICPH 2671 (Saxena et al, 2013b) and ICPH 2740 (Saxena et al, 2013c)] were released in India. Even though, very less improvement was occurred in the productivity of pigeonpea.…”
