豌豆属（豆科）由 5 个亚属组成，包括 100 多种野生物种。在 Vigna，已经驯化了来自 Vigna、Plectrotropis 和 Ceratotropis 三个亚属的 10 种作物。野生绿豆物种的栖息地如此多样化，以至于它们的基因组可能含有负责适应环境压力的各种基因，这可能会带来农业创新。由于维尼亚基因库中的一些种质尚未鉴定，而且它们似乎是新的遗传资源，因此根据形态特征对这些种质进行了鉴定。根据核 rDNA-ITS 和叶绿体 atpB-rbcL 间隔区的 DNA 序列估计系统发育位置。根据这些结果，最近描述的物种 V. indica 和 V. sahyadriana 以及一些野生绿豆物种，即 V. aconitifolia、V. dalzelliana、V. khandalensis、V. marina var. 的潜在用途。讨论了 oblonga 和 V. vexillata。
The genus Vigna (Fabaceae) consists of five subgenera, and includes more than 100 wild species. In Vigna, 10 crops have been domesticated from three subgenera, Vigna, Plectrotropis, and Ceratotropis. The habitats of wild Vigna species are so diverse that their genomes could harbor various genes responsible for environmental stress adaptation, which could lead to innovations in agriculture. Since some of the gene bank Vigna accessions were unidentified and they seemed to be novel genetic resources, these accessions were identified based on morphological traits. The phylogenetic positions were estimated based on the DNA sequences of nuclear rDNA-ITS and chloroplast atpB-rbcL spacer regions. Based on the results, the potential usefulness of the recently described species V. indica and V. sahyadriana, and some wild Vigna species, i.e., V. aconitifolia, V. dalzelliana, V. khandalensis, V. marina var. oblonga, and V. vexillata, was discussed.
