A Preliminary Study Of Environmental Effect Of Transgenic Cotton To The Rhizosphere Microorganisms And Cotton Field Pests In The Plant Breeding Base Of Hainan

Hainan is a natural greenhouse of our country, it has unique light and temperature climate conditions and resources, it is fit for a variety of different crops especially in winter. With the research and development of GM crops, GM crops has rapid development in recent years, GM material prosperity has been correspond increase in the Plant Breeding Base of HaiNan, it urgent need to study a scientific basis for GM crops for environmental safety, it is eager to solve this safety problem of transgenie cotton crops in the Plant Breeding Base of HaiNan.The safety assessment of transgenie crops is an important issue for public concern. This study was taken at the Plant Breeding Base of Hainan. The influence of transgenie pest-resistant cotton SGK321 (BT/CPTI) of rhizosphere microorganisms and the field environmental safety was studied. By petri dish cultivation, counting and molecular identification, in nearly two-year's practice and experiment, primary results were obtained. No significant difference in the community diversity of rhizosphere microorganisms (bacteria, fungi, actinomyces) between SGK321 and Shiyuan321 were observed. The dynamics of the rhizosphere microbial community diversity were approximately the same. Moreover, except for the apparent difference in the abundance of Heliothis armigera, no distinct differences were observed in the other studied field pests.This study can carry out the relevant for GMO safety researching ultimately in the Plant Breeding Base of HaiNan, and it also can analysis contributed for its potential risks, and give initial measures for GM cotton standardization growing in the Plant Breeding Base of HaiNan, it also can give a good suggestion for GM cotton standardization growing and the construction of Hainan ecological province.
