Abstract:
  • 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.
