针对辽宁省野生小豆及其近缘野生种濒危情况日趋严重的问题,对辽宁省14个市的36个区(县)开展了野生小豆及其近缘野生种的抢救性搜集,并对搜集的资源进行了豆象抗性鉴定。结果表明,野生小豆Vigna angularis var. nipponensis主要分布于辽中和辽东地区,尤其是在辽东沿海区域,而近缘野生种Vigna radiata var. sublobata和Vigna minima则主要分布于辽西地区;共搜集到262份野生小豆及其近缘野生种种质资源;城市化进程的加快以及人类活动的影响是导致辽宁野生小豆及其近缘野生种濒危的主要原因;野生小豆及其近缘野生种在生长习性、茎秆、荚色和粒色等方面与栽培小豆Vigna angularis var. angularis具有明显差异。此外,本研究还对搜集的野生小豆及其近缘野生种进行了豆象抗性鉴定,筛选出2份高抗豆象和1份抗豆象资源,这是国内外首次发现的抗豆象小豆资源。本研究结果为我国野生小豆及其近缘野生种的珍稀濒危资源保护和利用提供了重要依据,同时为小豆抗豆象育种提供了珍贵的种质资源。
In response to the increasing endangerment of wild adzuki bean and its wild relatives in Liaoning province, a rescue-oriented collection effort was conducted across 36 districts (counties) in 14 cities within the province. The collected resources were evaluated for bruchid resistance. The results revealed that Vigna angularis var. nipponensis are primarily distributed in the central and eastern regions of Liaoning, especially along the eastern coastal areas, while Vigna radiata var. sublobata and Vigna minima are mainly found in the western regions. A total of 262 germplasm accessions of wild adzuki bean and its wild relatives were collected. The study highlights the severe endangerment of these species in Liaoning province, with urbanization and human activities identified as the primary drivers of this threat. Significant differences were observed between wild and cultivated adzuki bean in growth habits, stem characteristics, pod color, and seed color. Additionally, the evaluation of bruchid resistance identified two highly resistant and one resistant germplasm accessions. This is the first time that bruchid-resistant adzuki bean resources have been identified both domestically and internationally. These findings provide a critical foundation for the conservation and utilization of rare and endangered wild adzuki bean resources and its wild relatives in China and offer valuable germplasm for breeding bruchid-resistant adzuki bean cultivars.
