摘　　要：通过多点多品种试验,对常规棉品种与杂交棉品种主要性状之间的差异进行了分析。结果表明常规棉品种比杂交棉品种:在生育性状方面表现为营养生长较旺盛,生育期偏长,株高较高;在产量性状方面,单位面积成铃数多,籽棉产量高,但衣分低1.5个百分点,皮棉产量两者相当;在纤维品质性状方面,总体上常规棉品种要好于杂交棉品种。在棉花生产中可以应用近期选育出的常规棉品种,同时适当加大种植密度;今后常规棉品种的选育目标应注重缩短生育期和提高衣分。This paper study the differences between the main characteristics of conventional cotton and hybrid cotton cultivars through the multi variety test in 2013.The results show that：the conventional cotton varieties than hybrid cotton varieties,growth traits in vegetative growth period,growth period is longer,higher plant height;the yield per unit area,boll number,seed cotton yield high,but it is lower by 1.5% in lint,the yield is equivalent;in the aspect of fiber quality traits,conventional cotton varieties are general better than hybrid cotton variety.conventional cotton varieties Can be used in cotton production,while increasing planting density;breeding goal in conventional cotton varieties should pay attention to shorten the growth period and increase the lint percentage.
