摘要
2003年,在山东尹庄、江苏扬州、安徽宿松、湖北荆州、湖南长沙、湖南南县、湖南澧县等7个地点,对包括对照中29在内8个组合的F1、F2代共计16个材料进行纤维品质的比较研究,结果表明:抗虫杂交棉F1和F2代间除纤维长度达到显著差异外,其他7项指标差异均无显著,但F2代纤维品质变异范围增大,劣质纤维比例增加,优良纤维比例减少,从而出现纤维品质的衰退。
A comparative study was Province, Yangzhou of Jiangsu Province, carried out respectively in 7 Susong of Anhui Province, trial spots in Yinzhuang of Changsha, Nanxian Lixian Province in 2003, using F1 and F2 generations of 8 bollworm - resistance hybrid crosses including C Shandong of Hunan K as studying materials. The results were as follows： Although there was not prominent difference among the other 7 fiber indexes of F1 and F2 generations except for the fiber length, the fiber quality of F2 generation declined because of the increase of poor fiber and the decrease of fine fiber.
