姑娘薯是广西防城港东兴市的一个古老地方甘薯品种,已有200多年的种植历史,一直以来作为当地主栽的甘薯品种来种植,虽然有一定的种植面积,但处于散户种植状态,没有形成规模,影响力不大,为自产自销状态,未能远距离往外销售.2005年后得到当地村委、乡镇(市)农业部门及政府的关注和重视,下拨科技经费支持科技人员开展姑娘薯的栽培技术研究工作,并将姑娘薯命名为红姑娘红薯进行对外宣传,这些工作措施提高了姑娘薯的知名度,促进了姑娘薯产业的发展,姑娘薯也因此获得了国家农产品地理标志证书和广西名牌产品等一系列荣誉称号,产品曾一度远销省外,甚至国外.姑娘薯产业逐步发展成为东兴市乃至防城港市一大特色农业产业,成为种植户主要的收入来源之一,对当地的产业扶贫及乡村振兴作出了积极的贡献,但是随着市场环境的变化,也遇到了诸如种性退化及销售渠道不顺畅等诸多问题.为此,对姑娘薯的研究现状及开发利用进展进行总结,分析姑娘薯产业存在的问题,提出相关的工作建议,为提高姑娘薯的品种保护和多元化开发利用力度,加快推进姑娘薯良种化进程及产业发展提供参考,同时为该种质的改良创新和品种选育提供一定的理论依据.

[Objective]The present study was aimed to screen molecular marker primers showing high polymorphism in order to study genetic diversity amongst Guangxi wild soybean(Glycine soja) germplasm.[Method]The genetic diversity amongst 22 Guangxi wild soybean germplasm materials,collected at different periods,was analyzed by using 60 pairs of SSR primers.[Result]The results indicated that the allelic variation of 60 SSR primers ranged from 1.0 to 8.0 with an average of 3.5/primer.Twenty-three SSR primers showed better polymorphism with allelic variation above 4.A distinct allelic variation of SSR primers in different linkage groups was observed which ranged from 1.67 to 5.00.Amongst all the linkage groups,group J showed the least allelic variation(1.67),while it was the highest(5.00) in B2 and H groups.[Conclusion]The screened polymorphic SSR primers were suitable for studying genetic diversity of Guangxi wild soybean.
