| 摘 要： | 为查明青海地区晚疫病菌单倍型分布情况，本研究对青海不同地区采自2006～2007年的70个晚疫病菌材料的线粒体单倍型进行了分析，结果表明：94.3%的菌株为Ⅱa型，5.7%的菌株为Ⅱb型，其中Ⅱb型均分离自番茄。这说明青海地区马铃薯晚疫病菌群体类型比较单一，主要为Ⅱa型，线粒体单倍型不存在多态性。

| Abstract: | To detect the distribution of mitochondrial haplotypes of Phytophthora infestans in Qinghai Pro-vince,70 isolates of Phytophthora infestans collected from different areas in 2006-2007 were identified and analyzed.The results showed that the typeⅡ a was the most important,accounting for 94.3%,and the rest 5.7% belong to the typeⅡb.The typeⅡb strains were all isolated from tomato plants.The results showed that the typeⅡa was the major potato Phytophthora infestans strain in Qinghai,and its mitochondrial haplotype was simplistic. |
