摘　　要：采用田间调查方法,对27个棉花育种材料的产量与纤维品质指标进行比较分析.结果表明,材料间籽棉、皮棉产量差异很大,籽棉产量最高的为3509.7kg/hm2,最低的为1153.0kg/hm2,皮棉产量最高的为1410.8kg/hm2,最低的为475.3kg/hm2,材料间纤维品质存在明显差异.综合产量与品质指标,27个育种材料中6-3、6-20的纤维品质好,产量性状表现良好,可直接利用.The yield and fiber quality indicators of 27 cotton varieties have been observed through field experiment. The results showed that the yield of seed cotton and that of lint cotton among species produced significant differences. The maximum yield of seed cotton reached 3 509.7 kg/hm^2 and the minimum value was 1 153.0 kg/hm^2, indicating a difference, 2 356.7 kg/hm^2 , and for lint production the maximum yield reached 1 410.8 kg/hm^2 and the minimum yield was 475.3 kg/hm^2, indicating a difference of 935.5 kg/hm^2. The fiber quality among varieties presented also significant differences. Comprehensive analysis of production and quality targets indicated, varieties 6-3,6-20 of 27 species carry good quality of fiber and have good yield characters available for the cotton product.
