Investigation,Collection,and Bruchid Resistance Identification of Wild Adzuki Bean and Its Wild Relatives in Liaoning Province
摘要
Abstract
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.关键词
