| 摘 要： | 广西是大豆花叶病发生较为严重的地区,大豆花叶病毒株系SC15及SC18株系是广西区内主要流行株系。为了调查广西本地大豆种质对这两个流行株系的抗性,采用人工接种的方法对160份广西本地春大豆种质进行抗性鉴定。结果显示:桂下湾灰地豆、小青豆(桂平)、小青豆-1(上思)、横县黑豆-1、横县黑豆-2、横县黑豆-3、那坡黑眼豆、隆林蛇场本地豆8份种质对SC15株系高抗,占所鉴定材料总数的5%;石塘五月黄、灌阳黄豆、凤山早黄豆、三石六月黄、两造黄豆、横县黑豆-1、田黑豆7份春大豆种质对SC18株系表现抗浸染,占所鉴定材料总数的4.37%。所鉴定的广西春大豆种质中,抗SC15株系的抗病种质抗性级别低,没有对SC15株系完全免疫的大豆种质;而抗SC18株系的大豆种质抗性级别比SC15株系高,其中有7份春大豆种质对SC18株系免疫。从抗性鉴定结果看,SC18株系对广西春大豆的致病力比SC15株系弱。因此SC15株系对大豆生产的危害更为严重,是更为值得重视的一个强毒株系。本研究筛选出的抗SMV春大豆种质可作为抗源材料用于大豆抗病育种及抗性相关的研究。

| Abstract: | Soybean mosaic virus(SMV) is a very serious disease of soybean in its cultivation in Guangxi,where the strain SC15 and SC18 are the most prevalence strains. In order to screen for resistant materials to these two popular SMV strains,160 Guangxi spring-sowing soybean germplasms were inoculated with those two strains in two independent experiment. The results showed that 8 soybeans germplasms(Guixiawanhuididou, Guipingxiaoqingdou, Shangsixiaoqingdou-1, Hengxianheidou-1, Hengxianheidou-2, Hengxianheidou-3, Napoheiyandou, and Longlinshechangbendidou) were highly resistant to strain SC15, accounting for 5% of the tested soybean germplasms. Shitangwuyuehuang, Guanyanghuangdou, Fengshanzaohuangdou, Sanshiliuyuehuang, Liangzaohuangdou, Hengxianheidou-1, Tianheidou were resistance in infection to strain SC18, accounting for 4.37% of the tested soybean germplasms. In all those tested spring-sowing soybean germplasms, no immune germplasm was found to SC15 and the resistant rand was lower than SC18 for the resistant germplasms. There were 7 soybean germplasms immune to strain SC18. It showed that strain SC15 is virulent strain, and strain SC18 is less virulent strain, we should pay more attention to strain SC15 prevalence in soybean planting regions. Furthermore, the resistant germplasms could be used in soybean breeding, production and SMV related researches. |
