摘　　要：采用目测法调查棉田盲蝽混合种群发生数量,并结合盲蝽对棉花植株的危害程度,对162个供试棉花品种(系)进行了抗盲蝽鉴定及评价。共计筛选获得包括亚洲棉、灵-29、07生试6号等16个对盲蝽具有抗性潜力的棉花品种(系),以及辽阳多毛棉、冀丰989、08生试6号、大铃668、石抗338、HB5 6个对盲蝽敏感的棉花品种(系)。初步建立了棉花品种(系)抗盲蝽田间鉴定与评价技术规程,为棉花抗盲蝽育种提供了种质资源及技术参考。A visual survey of insect population density and degree of plant damage was performed to assess the resistance of 162 cotton varieties to mirid bugs in cotton fields. The 16 varieties with the greatest resistance to mirid bugs, including Asian cotton, Ling-29 and 07 Shengshi NO. 6. Six varieties were found to be sensitive to mirid bugs, including Liaoyangduomaomian, Jifeng989, and Jifeng989, 08 Shengshi NO. 6, Daling668, Shikang338 and HB5. Based on these results, a set of primary technical criteria for evaluating the field resistance of cotton varieties to mirid bugs was established that can be used to breed mirid bug- resistant cotton lines.
