5个杂交彩色棉产量及主要农艺性状比较研究

Comparative study on yield and main agri-characters of five hybrid colored cotton varieties

对5个杂交彩色棉新品种（系）的产量及主要农艺性状进行了比较研究,结果表明,在5个供试品种（系）中,淮棕杂1号生育进程快,农艺性状较好,叶面积大,吐絮期叶面积下降缓慢,干物质积累多,成铃结构合理,优质铃比例高,实产籽棉3 298.5 kg·hm^-2,产量与一般白色棉相当,较棕长绒4个品种（系）增产籽棉51.7%～90.1%.

In this paper,yields and main agri-characters of 5 hybrid colored cotton varieties were compared. The results showed that among 5 varieties, Huaizongza 1 was superior in the aspects of growth, agri-characters,leaves areas, dry matter accumulation and boll setting to others. The seed cotton yield of Huaizongza 1 was 3 298.5 kg· hm^- 2（no significant difference with common cotton varieties） , and increased by 51.7% to 90. 1% than that of other 4 varieties.
