    水稻品种‘桂育11号’对褐飞虱的抗性评价

    Resistance evaluation of rice variety ‘Guiyu 11’ to Nilaparvata lugens

      摘要
    • 摘要:
      目的  明确水稻品种‘桂育11号’对褐飞虱Nilaparvata lugens的抗性，为该虫的绿色防控提供技术支撑。
      方法  采用苗期鉴定、蜜露分泌量测定、成株期室内评价以及田间数量调查方法对‘桂育11号’进行褐飞虱抗性系统评价。
      结果  ‘桂育11号’苗期与抗虫对照品种‘Rathu Heenati’均表现为中抗；分蘖期和孕穗期，褐飞虱在‘桂育11号’上取食24 h后的平均蜜露分泌量均与在‘Rathu Heenati’上的差异不显著；在室内成株期接虫15 d后‘桂育11号’和‘Rathu Heenati’植株生长正常，感虫品种‘TN 1’植株全部枯死；褐飞虱田间虫口密度动态调查发现，以水稻百丛植株的平均虫量计，2019年6月19日和6月24日‘桂育11号’上褐飞虱分别为218.33和436.67头，均显著低于感虫品种‘柳沙油占202’上的。
      结论  ‘桂育11号’对褐飞虱表现为中抗，田间种植对褐飞虱种群增长具有显著的抑制作用，可应用于褐飞虱绿色防控。

       

      Abstract:
      Objective  To determine the resistance of rice variety ‘Guiyu 11’ to brown planthopper, Nilaparvata lugens, and provide technical supports for green control of N. lugens.
      Method  The resistance of ‘Guiyu 11’ to N. lugens was systematically evaluated using seedling screening test, honeydew excretion measurement, laboratory evaluation of adult-plant and field investigation of N. lugens populations.
      Result  ‘Guiyu 11’ and the resistant variety ‘Rathu Heenati’ (as the control) showed moderate resistance to N. lugens at seedling stage. The average quantity of honeydew secreted by N. lugens after feeding on ‘Guiyu 11’ for 24 hours was not significantly different from that of ‘Rathu Heenati’ at tillering and booting stages. At adult-plant stage, ‘Guiyu 11’ and ‘Rathu Heenati’ plants grew normally after infected by N. lugens for 15 days, while all plants of the sensitive variety ‘TN1’ withered and died. The field investigation of dynamic insect density showed that the average numbers of N. lugens on ‘Guiyu 11’ on June 19 and June 24 in 2019 were 218.33 and 436.67 per hundred clump, respectively, and were significantly lower than that on the sensitive variety ‘Liushayouzhan 202’.
      Conclusion  ‘Guiyu 11’ is moderately resistant to N. lugens and shows significant inhibiting effect on the growth of N. lugens population in paddy field. ‘Guiyu 11’ can be applied to the ecological control of N. lugens.
