大豆种质资源对大豆胞囊线虫3号生理小种的抗性评价

2006-2014年,应用病土盆栽方法,对来自于12个省(市)的779份大豆种质资源进行了大豆胞囊线虫3号生理小种的抗病性鉴定。鉴定材料来源于吉林省539份、黑龙江省58份、辽宁省51份、山西省16份、内蒙古17份、河北省10份、北京市42份、安徽省5份、广西壮族自治区14份、河南省17份、山东省6份、江苏省4份。从中选出19份抗病种质,占鉴定总数的2.44%,分别是FY001-3、W93155、JH229、HJ01-1900、W94128-8、YX04-6561、W7491、W201102-25、Q30、Q31、HK6、HK7、BN9、CM2008-12、JY407、Q32、Q28、Q33、BN10,按抗病种质在各省份鉴定材料中所占的比例来看,山东省大豆种质抗病比例最高,占83.33%,其次是黑龙江省占15%。这些品种(系)的农艺性状优良,可直接作为抗性亲本应用于育种。

Evaluation of Resistance of Soybean Germplasm to Race 3 of Soybean Cyst Nematode

The resistance of 779 soybean germplasms from 12 provinces (municipalities) to soybean cyst nematode race 3 were evaluated by pot culture with infected soil during 2006-2014.The materials are from 535 in Jilin province,58 in Heilongjiang province,51 in Liaoning province,16 in Shanxi province,17 in Inner Mongolia,10 in Hebei,42 in Beijing,5 in Anhui,14 in Guangxi,17 in Henan,6 in Shandong province,4 in Jiangsu province.19 resistant germplasms were selected,accounting for 2.44％ of the total.They were Fengyuan 001-3,W93155,Jihuang 229,Hejiao 01-1900,W94128-8,YX04-6561,W7491,W201102-25,Qihuang 30,Qihuang 31,Kangxian 6,Kanxian 7,Bainong 9,CM2008-12,Jiyu 407,Qihuang 32,Qihuang 28,Qihuang 33,BN10.According to the proportion of resistant germplasm in the total from each province,the highest is Shandong province,accounting for 83.33％.Followed by Heilongjiang province accounting for 15％.These varieties (lines) could be used as resistance parents in breeding.
