摘要: 选用7个转基因抗虫棉品种WH1、WH2 、WH3 、WH4 、WH5、WH6、BG2 和一个常规种泗棉 3号 (CK),在10个生态环境不同的试验点,对它们的抗虫特性和产量性状的适应性进行了研究.结果表明,转基因抗虫棉对棉铃虫 (Helicoverpa armigera)、棉红铃虫 (Pectinophora gossypiella)抗性很强,并且不受生态环境差异的影响,稳定程度较高.但其产量性状受环境影响较大,品种和试验点的互作效应显著.与对照相比,WH6和BG2 的抗虫性和丰产性较好,可以在生产上应用.

Abstract: Seven transgenic strains of insect-resistance cotton,WH1,WH2,WH3,WH4,WH5,WH6 and BG2,and one common strain Simian-3 (CK) were selected to investigate their adaptation to insect-resistance and yield trait at 10 different sites.The results show that all transgenic strains had a strong resistance to bollworm(Helicoverpa armigera) and pink bollworm (Pectinophora gossypiella),with a high stability and no difference in 10 sites,but the yield trait was significantly influenced by environmental factors.The interaction between strains and sites was significant. In comparison with CK,WH6 and BG2 had a good insect resistance and high fiber yield,and could be applied in practice.
