| Abstract: | The yield,disease-resistance and fiber quality of 39 cotton varieties bred by Hubei province were studied since the Tenth five-year plan. The results showed that the yield components of the varieties increase significantly, In addition, the varieties with resistance against fusarium wilt amounts to 20% merely, and the resistance against vertieillium wih resistant has no manifest progress. According to the analysis, fiber length,fiber strength and Micronaire-value are improved to some extent, the lint percentage before frost, plant height, bolls per plant and single boll weigh increase, and the growth period decrease,and lint percentage is relatively stable. Finally, bolls per plant and single boll weight of hybrid cotton have obvious advantages over the conventional cotton, which lead to its highest yield. |
