Abstract: Plasmid p G4AB containingBtgene was transferred into cotton Zhong 23 via pollon tube pathway.The Kanamycin detection and the expression ofBtICP,PCR were used to analyze the self-pollination generations from transgenic cotton Zhong 23.The results were as follows.ExogenousBtgene was amplified and expressed in the Kanamycin-resistance transgenic cotton.TheBtgene andnpt IIgene were inserted into the transgenic cotton genome,they were linked and inherited stably in different generations.npt IIgene can be used in inheritance analysis ofBtgene.

Key words: Btgene, npt IIgene, Inheritance, Expression
