Micronutrient malnutrition or hidden hunger is a serious challenge toward societal well-being. (Lam.) Kuntz (known locally as ), is an underutilized legume that has the potential to be a global food legume due to its rich nutrient profile. In the present study, 99 accessions of were tested for iron (Fe), zinc (Zn), calcium (Ca), protein, and phytate concentrations over two locations for appraisal of stable nutrient-rich sources. Analysis of variance revealed significant effects of genotype for all the traits over both locations. Fe concentration ranged from 29.35-130.96 mg kg whereas Zn concentration ranged from 19.44 to 74.20 mg kg across both locations. The highest grain Ca concentration was 251.50 mg kg whereas the highest grain protein concentration was recorded as 25.73%. In the case of grain phytate concentration, a genotype with the lowest value is desirable. IC622867 (G-99) was the lowest phytate containing accession at both locations. All the studied traits revealed highly significant genotypic variances and highly significant genotype × location interaction though less in magnitude than the genotypic variance. GGE Biplot analysis detected that, for grain Fe, Zn, and Ca concentration the 'ideal' genotypes were IC331457 (G-75), IC331610 (G-76), and IC553564 (G-60), respectively, whereas for grain protein concentration IC553521 (G-27) was the most "ideal type." For phytate concentration, IC351407 (G-95) and IC550523 (G-99) were considered as 'ideal' and 'desirable,' respectively. Based on the desirability index, Location 1 (Kanpur) was identified as ideal for Fe, Zn, Ca, and phytate, and for grain protein concentration, Location 2 (New Delhi) was the ideal type. A significant positive correlation was detected between grain Fe as well as grain Zn and protein concentration considering the pooled analysis over both the locations where as a significant negative association was observed between phytate and protein concentration over the locations. This study has identified useful donors and enhanced our knowledge toward the development of biofortified cultivars. Promoting domestication of this nutrient-rich semi-domesticated, underutilized species will boost sustainable agriculture and will contribute toward alleviating hidden hunger.
微量营养素营养不良或隐性饥饿是对社会福祉的一项严峻挑战。（Lam.）Kuntz（当地称为 ）是一种未得到充分利用的豆科植物，因其丰富的营养成分，有潜力成为全球食用豆类。在本研究中，对99份该植物种质在两个地点进行了铁（Fe）、锌（Zn）、钙（Ca）、蛋白质和植酸盐浓度的测试，以评估稳定的富营养源。方差分析表明，在两个地点，所有性状的基因型效应均显著。两个地点的铁浓度范围为29.35 - 130.96毫克/千克，锌浓度范围为19.44至74.20毫克/千克。最高籽粒钙浓度为251.50毫克/千克，最高籽粒蛋白质浓度记录为25.73%。就籽粒植酸盐浓度而言，希望有一个值最低的基因型。IC622867（G - 99）在两个地点都是植酸盐含量最低的种质。所有研究性状均显示出高度显著的基因型变异以及高度显著的基因型×地点互作，尽管其幅度小于基因型变异。GGE双标图分析检测到，对于籽粒铁、锌和钙浓度，“理想”基因型分别为IC331457（G - 75）、IC331610（G - 76）和IC553564（G - 60），而对于籽粒蛋白质浓度，IC553521（G - 27）是最“理想类型”。对于植酸盐浓度，IC351407（G - 95）和IC550523（G - 99）分别被视为“理想”和“期望”类型。基于期望指数，地点1（坎普尔）被确定为铁、锌、钙和植酸盐以及籽粒蛋白质浓度方面的理想地点，而对于籽粒蛋白质浓度，地点2（新德里）是理想类型。在对两个地点的汇总分析中，籽粒铁以及籽粒锌与蛋白质浓度之间检测到显著正相关，而在各地点植酸盐与蛋白质浓度之间观察到显著负相关。本研究确定了有用的供体，并增进了我们对培育生物强化该植物品种的认识。推广这种营养丰富的半驯化、未充分利用物种的驯化将促进可持续农业发展，并有助于缓解隐性饥饿。
