摘要
大豆花叶病毒(SMV)株系SC9是浙江省大豆产区的流行株系。利用对该株系表现抗病的鲜食大豆材料开心绿宝石、辽02-M03、23037-1、闽豆5号与感病材料浙鲜豆4号、南农1138-2、11W68配制抗感和抗抗杂交组合。通过人工摩擦接种法进行鉴定,分析鲜食大豆抗病品种对株系SC9的抗性遗传及等位性。结果表明:开心绿宝石、辽02-M03、23037-1、闽豆5号与感病材料杂交的F1代均表现抗病,F2群体表现3抗∶1感的分离比例,F2∶3家系表现1抗∶2分离∶1感的分离比例,表明4份抗源材料对SC9的抗性由单显性基因控制。抗抗组合开心绿宝石×辽02-M03的F2群体和F2∶3家系全部表现抗病,表明开心绿宝石与辽02-M03对SC9的抗性基因是等位或紧密连锁的。而抗抗组合闽豆5号×辽02-M03的F2群体表现15抗∶1感的分离比例,表明闽豆5号与辽02-M03对SC9的抗性基因是不等位的,而且独立遗传。
Soybean mosaic virus （SMV） strain SC9 was popular in soybean producing areas of Zhejiang province. Soybean re-sistant （R） cultivars Kaixinlvbaoshi, Liao 02-M03, 23037-1, Mindou 5 were crossed respectively with susceptible （S） cuhi-vats Zhexiandou 4, Nannong1138-2, 11 W68 and resistant parents were also crossed with each other. Inheritance and allelism analysis of resistance to strain SC9 in vegetable soybean was carried out by using the artificial friction inoculation. All of the Fz lines derived from the R x S cross combinations were resistant and all of the F2 and F2：3 lines exhibited a segregation pattern of 3 R： 1 S and 1 R： 2Seg： IS ratio, respectively. The results showed that the four soybean cultivars carried single dominant resistant gene for strain SC9, respectively. The F2 populations and F~：3 lines from Kaixinlvbaoshi x Liao 02-M03 were all resistant. Therefore, the resistance genes between Kaixinlvbaoshi and Liao 02-M03 were allelic or closely hnked. The F2 populations from Mindou 5 × Liao 02-M03 exhibited a segregation pattern of 15R： 1S. The results showed that the resistance genes between Mindou 5 × Liao 02-M03 were not at the same locus. These results are important for vegetable soybean resistance breeding pro-grams.
