Lack of significant growth in the world average yield in upland cotton since 1991 reinforces the impression that the cotton industry has entered into a long梩erm period of slow growth in production. Breeding contribution to the yield growth has sharply decreased, and the result of cotton cultivar performance of regional test displayed that the potentials for the growth of yield in new developed cultivars was delimited, which implies that we must pay more attention to the studies on the diversity of cotton cultivers and genetic mechanism for yield traits.

Different plant expression vectors had been respectively transferred into upland cotton cultivars Jinman12, Jinmian7, Xinluzao1 and Jihe321 via Agrobacterium tumfaciens transformation. These vectors carried cryIAc3 gene, which encodes Bacillus thuringiensis δ-endotoxin, under the control of chimeric OM promoter, CaMV 35S promoter, and cotton leaf curl virus RP promoter respectively; snowdrop lectin gene (Galanthus nivals agglutinin, gna) trans-regulated by rolC promoter controlled TGAla factor; and multivalent expression construct of both cryIAc3-cpti fusion gene and gna gene. A large number of transgenic plants and their progenies had been obtained.
