Vigna umbellata (Thunb.) or Rice bean is a tropical to temperate grain legume which is a hotspot for biological diversity and an economically important crop in Asia. Rice bean is a multipurpose legume and underutilised (Joshi et al., 2008). Its distribution pattern indicates great adaptive polymorphism for diverse environments, with its distribution ranging from humid tropical to sub-tropical, to sub-temperate climate. Rice bean is a locally important contributor to human nutrition in parts of India and South-East Asia. Like many grain legumes, rice bean seeds contain antinutritional factors. Antitrypsin activity is notable though comparable to that of cowpea (Vigna unguiculata) and black gram (Vigna mungo). For the improvisation of nutritional factors to consume, exploring genome content is essential. As rice bean can translate to a model legume plant along with its other associated species, genetic research using whole genome sequencing will boost and accelerate its breeding by impacting allied and applied approaches towards extensive consumption of this variety. to improvise nutritional factors, exploring genome content is essential.

饭豆（Vigna umbellata (Thunb.)，英文名Rice bean）是一类分布于热带至温带的粮用豆科作物（grain legume），兼具生物多样性热点物种与亚洲重要经济栽培作物的双重属性。饭豆属于多用途豆科作物，但尚未被充分开发利用（Joshi et al., 2008）。其分布格局显示出对多样生境的极强适应性多态性，分布范围涵盖湿润热带、亚热带至亚温带气候区。在印度部分地区与东南亚区域，饭豆是当地人类膳食营养的重要供给来源之一。与多数粮用豆科作物类似，饭豆种子含有抗营养因子，其中抗胰蛋白酶活性较为显著，但与豇豆（Vigna unguiculata）和黑绿豆（Vigna mungo）的抗胰蛋白酶活性水平相当。为改善其食用营养品质，对其基因组信息进行探索至关重要。鉴于饭豆及其近缘类群可作为豆科模式植物，采用全基因组测序开展遗传学研究，将通过推动相关应用研究方法的发展，促进并加速该作物的育种进程，从而助力其大规模推广食用。若要进一步优化其食用营养品质，基因组内容的探索仍是必要前提。
