“…SNPs are markers of choice owing to their ubiquitous nature and abundance in the genome. SNPs have been identified in pigeon pea [ 63 ], cluster bean [ 64 ], winged bean [ 65 ], dolichos bean [ 66 ], and cowpea [ 67 ] for potent use in genomics assisted breeding. Once the choice of marker system is established, it draws a path for mapping traits of interest leading towards fine mapping and cloning.…”

Vegetable legumes are an essential source of carbohydrates, vitamins, and minerals, along with health-promoting bioactive chemicals. The demand for the use of either fresh or processed vegetable legumes is continually expanding on account of the growing consumer awareness about their well-balanced diet. Therefore, sustaining optimum yields of vegetable legumes is extremely important. Here we seek to present d etails of prospects of underexploited vegetable legumes for food availability, accessibility, and improved livelihood utilization. So far research attention was mainly focused on pulse legumes’ performance as compared to vegetable legumes. Wild and cultivated vegetable legumes vary morphologically across diverse habitats. This could make them less known, underutilized, and underexploited, and make them a promising potential nutritional source in developing nations where malnutrition still exists. Research efforts are required to promote underexploited vegetable legumes, for improving their use to feed the ever-increasing population in the future. In view of all the above points, here we have discussed underexploited vegetable legumes with tremendous potential; namely, vegetable pigeon pea (Cajanus cajan), cluster bean (Cyamopsis tetragonoloba), winged bean (Psophocarpus tetragonolobus), dolichos bean (Lablab purpureus), and cowpea (Vigna unguiculata), thereby covering the progress related to various aspects such as pre-breeding, molecular markers, quantitative trait locus (QTLs), genomics, and genetic engineering. Overall, this review has summarized the information related to advancements in the breeding of vegetable legumes which will ultimately help in ensuring food and nutritional security in developing nations.

“…In the dolichos bean, as in other grain legumes, fixed growth habit and photoperiod insensitivity are considered domestication syndrome features ( Huyghe, 1998 ). Lablab, like other domesticated crops, exhibits a “founder effect” characterized by high phenotypic variability and low genetic variability, particularly in South Asian germplasm, whereas genetic diversity is higher in Africa ( Maass et al, 2005 ; Maass et al, 2010 ; Venkatesha et al, 2013 ).…”

Domestication is a dynamic and ongoing process of transforming wild species into cultivated species by selecting desirable agricultural plant features to meet human needs such as taste, yield, storage, and cultivation practices. Human plant domestication began in the Fertile Crescent around 12,000 years ago and spread throughout the world, including China, Mesoamerica, the Andes and Near Oceania, Sub-Saharan Africa, and eastern North America. Indus valley civilizations have played a great role in the domestication of grain legumes. Crops, such as pigeon pea, black gram, green gram, lablab bean, moth bean, and horse gram, originated in the Indian subcontinent, and Neolithic archaeological records indicate that these crops were first domesticated by early civilizations in the region. The domestication and evolution of wild ancestors into today’s elite cultivars are important contributors to global food supply and agricultural crop improvement. In addition, food legumes contribute to food security by protecting human health and minimize climate change impacts. During the domestication process, legume crop species have undergone a severe genetic diversity loss, and only a very narrow range of variability is retained in the cultivars. Further reduction in genetic diversity occurred during seed dispersal and movement across the continents. In general, only a few traits, such as shattering resistance, seed dormancy loss, stem growth behavior, flowering–maturity period, and yield traits, have prominence in the domestication process across the species. Thus, identification and knowledge of domestication responsive loci were often useful in accelerating new species’ domestication. The genes and metabolic pathways responsible for the significant alterations that occurred as an outcome of domestication might aid in the quick domestication of novel crops. Further, recent advances in “omics” sciences, gene-editing technologies, and functional analysis will accelerate the domestication and crop improvement of new crop species without losing much genetic diversity. In this review, we have discussed about the origin, center of diversity, and seed movement of major food legumes, which will be useful in the exploration and utilization of genetic diversity in crop improvement. Further, we have discussed about the major genes/QTLs associated with the domestication syndrome in pulse crops and the future strategies to improve the food legume crops.

“…In the dry and semi-dry land ecosystems, smallholder farmers nd this crop as a stable source of income [9]. The wider genetic diversity of lablab enables this crop to sustain a variety of climatic and environmental stresses [10][11][12]. Nonetheless, lablab promises to combat the "hidden hunger" -a most common problem in developing nations due to their high micronutrient content and climatic adaptation, thus helping to meet a few of the UN Sustainable Development Goals, like no poverty, zero hunger, and improved health and wellbeing [13][14] more speci cally in the countries like Africa [15], Asia, and Latin America even these nations neglect research and investment priorities of lablab [16].…”

Lablab purpureus, one of the most significant yet neglected and underutilized legume vegetable crops, has tremendous genetic variability in its traits, including growth habit, stem pigmentation, and pod color. Retrospectively, L. purpureus's systematic crop improvement efforts received less attention from researchers. In the current study, 11 local accessions of L. purpureus that were collected from various locations in Arunachal Pradesh-a global biodiversity hotspot, and their morphological and biochemical characteristics were examined. The conventional procedure for analyzing nutritional and anti-nutritional components found considerable variations for each of the characters under the study. The length, width, and pod color differed significantly across the eleven genotypes examined in the study. All accessions had good nutritional content and very low anti-nutritional elements, particularly the phytic acid was extremely low (1.77–2.43 mg/100gm) in the tender pod when compared to the lablab accessions of south Indian states as well as of common leguminous vegetables. The low phytate content assumes significance for enhanced mineral bioavailability, making its immature pods the potential functional food, thus, carving the pathways for mitigating the nutritional vulnerability in developing countries. These local accessions of lablab also represent an agronomically and nutritionally important pool for L. purpureus improvement/breeding.
