Abstract

The selective test of transgenic boll worm resistant cotton variety and demonstration experiments of cotton production were conducted in east and middle of Guanzhong cotton region of Shaanxi province from 2002 to 2003. The results showed that CCRI-41(double gene cotton Bt+CpTI) presented a good plant type structure, higher fruit branch, longer 1st and 2nd fruiting positions, rational spatial distribution of height, productive branches fruiting positions and leaves so that it may be strengthen ventilate and bright in the center space near stem. CCRI-41 was with more concentrative bolling, bigger boll and higher lint percent, better early-maturity, good adaptability to the local environment. In comparison with 33B,CCRI-41 lint yield,which raised more in normal year and reduced less in disaster one, was increased by 7.9%~39.8%. Meanwhile, it provided the combined technique for early-sample culture of CCRI-41.
