采用556份大豆种质资源为供试材料,在2006和2007年连续两年分别接种SMV1号和3号株系,对其成株抗性和种粒斑驳抗性均进行了鉴定。结果表明,接种1号株系的成株抗病资源446份,占80.2%;抗种粒斑驳资源107份,占19.2%;对成株和种粒斑驳均表现抗性的资源103份,占18.5%。接种3号株系的成株抗病资源151份,占27.2%;抗种粒斑驳资源87份,占15.7%;对成株和种粒斑驳均表现为抗性的资源76份,占13.7%。对1号和3号株系,在成株和种粒抗性上均表现抗病的资源69份,占12.4%。以上资源特别是兼抗资源在大豆生产和抗病育种中应予以重视。研究还显示,来自辽宁和吉林的供试资源对1号和3号株系的成株和种粒抗性均较好;来自中国农科院作物所和黑龙江的供试资源对1号株系的成株抗性较好,但对1号和3号株系的种粒抗性相对较差。
Using 556 soybean germplasm resources as test materials, SMV1 and No.3 lines were inoculated respectively for two years in 2006 and 2007, and their adult plant resistance and mottle of grain mottle were identified. The results showed that there were 446 resistant adult plants in inoculation line 1, accounting for 80.2% of the total, and 107 resistant to germplasm mottle, accounting for 19.2% of the total; 103 were resistant to both adult and seed mottle, accounting for 18.5%. Among them, 151 were resistant to adult plant disease, accounting for 27.2%; 87 were resistant to germplasm mottle, accounting for 15.7%; 76 were resistant to both adult and mottled seeds, accounting for 13.7% . For lines 1 and 3, 69 were resistant to both adult and seed resistance, accounting for 12.4%. The above resources, especially the anti-resources, should be valued in soybean production and disease-resistant breeding. The study also showed that the tested plants from Liaoning and Jilin had better resistance to both the adult and the seed of the No.1 and No.3 lines. The test resources from Crop Research Institute of Chinese Academy of Agricultural Sciences and Heilongjiang The resistance of the plants to No. 1 and No. 3 was relatively poor.
