陆地棉光籽品种资源分析和评价

Analyses and Evaluation of Naked Seed Variety Resources in Upland Cotton

从２０００多份陆地棉中筛选出１００份的光籽材料。进行农艺、经济性状分析的结果说明，光籽棉大多表现较为退化的性状，铃较小，衣分低，纤维细度差，种仁蛋白质含量低，含油量高；但纤维强度较好，这可作为提高纤维强度的资源；光籽性状受地理、气候等环境影响，变异较大，据此，有可能从中（尤其是稀毛、稀端毛光籽类）选育出综合性状较好的光籽品种。

Analyses ofagronomlc and economic characters ofover 100different naked seed varieties andstralnd sifted from more than 2000Upland cotton(G.hlrsutum) were carrledout.The resultslndicated that most naked seed cotton showed degenerated characters with a low ball weight and lint percentage, Low protein and high fat content of the kernel, poor fibre fineness,but a high fibre strengt.Naked seed cotton can be considered as one of the reslurces for Increaing fibre strength.Characters of naked seed,especially with sparse fuzz and fuzz only on seed ends,had a strong variation caused by varying environment such as geography and climate.It Is possible toget nakedseed varieties wlthadvancedcomprehenslve.haracters selected from these variated naked seed cotton.
