江西蔬菜种质资源调查收集与优异资源发掘

Investigation,Collection of Vegetable Germplasm Resources and Excellent Resources Discovery in Jiangxi

以"第三次全国农作物种质资源普查与收集行动"为契机,对江西省27个县(市、区)的402个村开展地方蔬菜种质资源的系统调查与收集,共收集到1817份蔬菜资源。通过对收集到的蔬菜地方品种资源的分布特点及其特异性分析,从抗病、抗逆、商品性、加工功能等不同方面筛选出10份优异地方蔬菜种质资源。通过接种鉴定评价,从本次收集的5份江西地方古老品种中筛选出高抗枯萎病的苦瓜种质资源3份。为蔬菜新品种选育和基础研究提供了丰富的物质基础及其信息。

As a sub-action of the Third National Survey and Collection of Crop Germplasm Resources,we have carried out the survey and collection of vegetable germplasm in 402 villages of 27 selected counties(cities or districts)in Jiangxi province.A total of 1817 vegetable accessions have been collected.The analysis of the geographic distribution and specificity of the collected local vegetable accessions suggested 10 elite accessions with elite traits on the disease resistance,stress resistance,commercial properties,and/or processing flexibility.Moreover,by testing for the disease resistance against Fusarium oxysporum using artificial root-soaking inoculation approach,three bitter gourd accessions with high wilt-resistance have been identified.Collectively,gained from the collection and evaluation of vegetable accessions,this work will provide the vegetable germplasm resource valuable in breeding for new varieties and in theoretical studies.
