Studies on Growth and Economic Characters of Bt Transgenic Cotton Varieties

doi:10.3321/j.issn:1000-7091.2000.01.014

Abstract

Abstract: Growth and economic characters and other morphological traits were studied with 5 Bt transgenic cotton varieties.The results showed that the growing processes of varieties R93-4,R93-6,RH-4 advanced and they ripped earlier compared with the control.Their fruit habit was much closer,owing to their insect resistance,and the bolls per plant were more than that of the control.But for their boll weight and lint percent both were lower,so in the practices of production corresponding measures should be adopted to raise the seed cotton yield of the transgenic cotton varieties.

Key words: Growth character, Economic character, Bt transgenic cotton
