| 摘 要： | 从采集的21个地点的48份土壤碎物和37株苜蓿病株上,收集到101株立枯丝核菌(Rhizoctonia solani Kühn)菌株.对101个立枯丝核菌菌株进行的菌丝融合群(AG群)判定表明,新疆部分地区苜蓿上的立枯丝核菌菌丝融合群有AG1、AG2、AG4和AG5,其出现频率分别为9.9;、46.5;、5.9;和35.6;.其中AG2和AG5分离频率较高,为优势融合群.

| Abstract: | In this study,101 Rhizoctonia solani Kühn strains were collected from 21 locations of 48 sites in the fragment and 37 plants in alfalfa diseased seedlings.According to the test of anastomosis groups(AGs),101 isolations of Rhizoctonia solani were categorized as follows: AG1、AG2、AG4、AG5.The occurrence frequency was 9.9%,46.5%,5.9% and 35.6% separately,among which AG2 and AG5 have higher frequency of separation rate and belong to the anastomosis groups. |
