| 1 | Inheritance of resistance to Helicoverpa armigera of 3 kinds of transgenic Bt strains available in upland cotton in China显示文摘There are 3 kinds of transgenic Bt strains, Shanxi 94-24, Zhongxin 94, and R19, in upland cotton in China. Their transgenic Bt insect-resistance cultivars or hybrids have been developed and grown by farmers. Genetic studies indicate that the resistance of the 3 transgenic Bt cotton strains to Helicoverpa armigera is controlled by one pair of non-allelic dominant genes. Linkage relationship between the resistant genes of R19 and Shanxi 94-24 transgenic Bt strains shows that they may be inserted in the same chromosome. FT hybrids crossed among the 3 strains show that high levels of protection from feeding damage are the same as that of their parents. Therefore, there is no co-suppression phenomenon in many transgenic plants. The results presented here afford a fundamental reliance in developing transgenic Bt insect-resistant cultivars and exploiting the heterosis of hybrids in upland cotton. | TANG Canming SUN Jing ZHU Xiefei GUO Wangzhen ZHANG Tianzhen SHEN Jinliang GAO Congfen ZHOU Weijun CHEN Zhixian GUO Sandui | 2000 | Chinese Science Bulletin2000，45，4： | 3 |
