[Adaptation of transgenic strains of insect-resistance cotton to different ecological environments].
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.
