摘要
2002-2003年采集了黄淮中北部地区为主的32个县市的大豆SMV病样981份,经初步繁殖鉴定、生物纯化及DAS-ELISA血清学检测,得到95个SMV分离物,根据95个分离物在27个鉴别寄主上的症状反应,最终确定南农1138-2、诱变30、8101、铁丰25、Davis、Bullfalo、早熟18、Kwanggyo、齐黄1号和科丰1号10个品种作为该地区SMV株系的鉴别寄主.利用它们可将95个SMV分离物划分成10个株系群,其中5个与以往鉴定株系群相同,另5个为新发现的株系群,分别将5个新株系群定名为SC-11～SC-15.研究还发现,SC-11株系群所占比例最大,是本地区优势株系;其次为SC-8株系群;SC-11和SC-13株系群分布最广,在黄淮北部各省均有分布.
Nine hundred and eighty-one diseased specimens of soybean leaves were collected from Middle and Northern Huang Huai Region in 2002 and 2003, and 95 SMV isolates were obtained using biological purification and serology （DAS-ELISA）. Based on symptomatic response of 27 differential hosts to these strains, Nannong 1138-2, Youbian 30, 8101 ,Tiefeng 25, Davis, Bullfalo, Zaoshou 18, Kwanggyo, Qihuang 1 and Kefeng 1 were chosen as the differential hosts for the identification of the SMV strain groups in Northern Huang Huai Region of China. The 95 SMV isolates were classified into 10 strain groups. Five new strain groups were discovered and named SC-11-SC-15. In Northern Huang Huai Region, SC-11 was preponderant, accounting for 21.1%. The second main strain group was the SC-8, accounting for 17.9%. The strain groups with the widest distribution were SC-11 and SC-13, which can be detected in all provinces of the region.
