通过对8个试种的转基因抗虫棉品种对棉铃虫抗虫性的对比试验和系统观察,表明中29F1、南抗3号和GK22等品种对棉铃虫的抗性较强,且丰产性能好,可作为治理棉铃虫的一项重要措施进行推广;杂交抗虫棉只有其F1代种有较高的使用价值,F2代性状分离严重,不宜在生产上推广使用。
The comparative experiments and systematic observation on the insect resistance of eight tested transgenic cotton varieties against cotton bollworm showed that the varieties of Zhong 29F1, NanKan3 and GK22 were more resistant to cotton bollworm and the yield was good , Which can be used as an important measure to control the bollworm. Poplar hybrid cotton only has higher value of its F1 hybrids. The F2 generation traits are separated seriously and should not be popularized in production.
