摘要
为了筛选出对红叶螨Tetranychus pueraricola抗性强的红小豆Vigna angularis品种,本研究采用叶片被害指数、盆栽虫口密度、螨量比值、叶绿素含量和田间自然种群密度5种抗性鉴定方法对13个红小豆品种的抗螨性进行评价。5种抗性鉴定方法在评价红小豆品种抗螨性上具有较高的一致性,彼此间的相关性均达到极显著水平(P<0.01)。田间自然种群密度法与螨量比值法,相关系数的绝对值最大达0.971,田间自然种群密度法可作为红小豆对红叶螨抗性的最佳评价方法。利用5种抗螨性鉴定方法的抗性指标进行系统聚类,将13个红小豆品种分为5大类,综合判断农垦红和珍珠红为高抗品种,天津红和中红7号为高感品种。红小豆不同品种对红叶螨抗感性的评价结果可作为黑龙江省红小豆田间品种布局的参考,对黑龙江半干旱地区杂粮作物害虫治理具有重要指导意义。
In order to screen out adzuki bean varieties with strong resistance,finding the best evaluation method of adzuki bean resistance to Tetranychus pueraricola,this study evaluated the mite resistance of 13 adzuki bean varieties by five identification methods,including harm index of leaves,insect density in pot plants,mite quantity ratio method,chlorophyll content and natural population density in the field.The results of correlation analysis showed that the five resistance identification methods had a high consistency,and the correlation among them reached a highly significant level(P<0.01).These methods can be used to evaluate the resistance of Vigna angularis varieties to T.pueraricola.The significant level of the correlation coefficient was the largest(0.971)between the field natural population density method and the mite ratio method,which could be used as the best evaluation method for the resistance evaluation.Based on the cluster analysis about resistance indexes of five mite resistance identification methods,13 red bean varieties were divided into five categories,and Nongken Red and Pearl Red were identified as high resistance level(HR)cultivars,and Tianjin Hong and Zhonghong No.7 were identified as high susceptibility level(HS)cultivars.The results of resistance identification can be used as the basis for cultivation layout of adzuki bean in Heilongjiang Province to continuously and effectively control the damage of tetranychus mite.In addition,the results of this study also provide the basis for selecting the identification methods of resistance plant to mite.
