| 摘 要： | 为摸清毕节地区主栽马铃薯品种对晚疫病的抗性情况,2007-2008年,在毕节、威宁、织金、赫章、黔西5县(市)不同生态区域开展了主栽马铃薯品种对晚疫病的田间抗性试验研究,结果表明:16个参试品种抗性存在明显差异,表现较好(中抗以上)的品种有7个(昭绿23号、昭绿4号、BP08、会-2、黔薯1号、威芋4号、鄂薯5号),只占参试品种的43.75%.因此,要不断加强新品种的引进、试验与示范及田间抗病性的监测,以便为品种的合理利用与布局提供科学依据.

| Abstract: | The field resistance of late blight of main cultivation varieties was identified in Bijie, Weining, Zhijin, Hezhang and Qianxi Counties of Bijie prefecture during 2007-2008 to know the late blight resistance of these main cultivation potato varieties. The results show that there is significant difference in resistance to potato late blight among 16 tested potato varieties and seven varieties (Zhaolu 23, Zhaolu 4, BP08, Hui-2, Qianshu 1, Weiyu 4 and Eshu 5) are of above middle resistance to potato late blight. Therefore, the introduction, test, demonstration and field resistance of new potato varieties should be enhanced to provide the scientific basis for rational utilization and distribution of potato varieties in Bijie prefecture. |
