| 摘 要： | 用田间种群密度、叶片为害指数和种群增长倍数 (实验室 ) 3个抗性指标作为评定标准 ,对 2 7个茄子品种抗侧多食跗线螨 Polyphagotarsonemus L atus( Banks)进行了系统聚类分析。结果表明 ,不同茄子品种对侧多食跗线螨抗性存在明显差异。相比较之下 ,丰研一号、种都万吨早茄、种都特别培育、成都墨茄、渝早茄 2号、湘研 2号和油罐茄7个品种为较强抗性品种 ;西安绿茄、种都皇太子、8819和湘研早茄 4个品种均为较易感品种 ;其余品种介于二者之间。同时表明 ,3个抗性指标之间相关性达极显著水平 ,因而 ,调查茄子品种抗该螨时选择 3个指标中的一个指标 ,既简便 ,又合理

| Abstract: | Using three resistant indexes,namely,field population density,index of leaf injury and population growth multiple (lab.) as resistant appraisal standards we studied the resistance of 27 eggplant varieties to Polyphagotarsonemus latus (Banks) with the cluster analysis.The results showed that the resistance of 27 eggplant varieties were significantly different.Comparatively,eggplant varieties,Fengyan 1, Zhongduwandunzao,Zhongdu special culture,Chengdumo,Yuzhao 2,Xiangyan 2 and Yonguan,had the strong resistantance;the varieties,8819,Xi'an green,Zhongduhuangtaizi and Xiangyanzao, were the most susceptible, and the others were middle between the above two. In addition, the results indicated that there were most significant correlations among 3 resistant indexes,and therefore,it is not only simple and convenient but accurate to take one resistant index instead of three resistant indexes in investigating eggplant varieties resistant to P.Latus. |
