Yield performance, cultivation characteristics of Sumian 29, and its selection and breeding process were introduced in the paper. Regional tests from 2010 to 2011 in Jiangsu Province showed that seed cotton yield and lint yield averaged 4 185 and 1 737 kg/hm2, and increased by 10.6% and 8.5% respectively, when compared with control (Siza 3). In production test, seed cotton yield and lint yield of Sumian 29 averaged 4 176 and 1 744.5 kg/hm2, respectively. Sumian 29 had high resistance to cotton bollworm, and also resistance to Fusarium wilt and Verticillium wilt of cotton. All of its fiber qualities achieved National Standard III and above. Sumian 29 has good application prospects.展开更多
