在2008年抗盲蝽棉花材料筛选的基础上,选出4个对盲蝽抗性较好的棉花材料和2个感盲蝽的棉花材料,分析其田间抗盲蝽性,并对其生长势和产量构成因素与目前2个主栽棉花品种做了比较,以评估这些棉花材料的应用价值。试验结果表明,表现出良好抗盲蝽性的品种HH1、BJ2、HH2的田间生长势和产量构成参数与抗虫棉中棉所41相当,优于常规棉中棉所49不喷施化学农药田。
On the basis of the screening of the cotton material of the litchi stink bug in 2008, four cotton materials with better resistance to the stink bug and two cotton stink bug were selected to analyze the anti-louse bugs in the field and their growth potential And yield components with the current two major cotton varieties were compared to evaluate the value of these cotton materials. The results showed that the parameters of field growth potential and yield of HH1, BJ2 and HH2, which showed good resistance to louse bugs, were similar to that of Bt cotton Cn41, which was better than that of Bt cotton C49 without spraying chemical pesticides .
