Summary:介绍了具有亚红叶标记的优质、高产彩色杂交棉新组合苏彩305的选育经过和农艺及品质性状。结果表明:该组合的籽棉产量264.5 kg/667 m2、皮棉产量94.8 kg/667 m2,分别比苏杂201( CK)增产11.65%、7.56%,具有明显的产量竞争优势;衣分35.82%,低于对照1.35个百分点;棉铃大,单铃重达6.3 g,比对照高0.9 g;纤维长度29.43 mm、整齐度指数84.6%、马克隆值4.45、伸长率5.5%、比强度34.20 cN/tex,综合纤维品质达优质Ⅱ型;具有亚红株标记,在苗床期观察子叶和小真叶即可区别真假杂种;通过在苗床去除绿苗杂株,可有效保证杂交F1群体的彩棉株率达98%以上。苏彩305利用双亲杂交互补优势,充分整合了亚红叶标记、优质、高产、抗虫等多个农艺性状,是一个在生产上具有推广潜力的彩色杂交棉新组合。

This paper introduced the breeding course , agronomic traits and quality traits of Sucai 305, a good-quality, high-yielding, colored and new hybrid cotton combination with insect-resistance and sub-red leaves.This combination had obvious com-petitive advantage in yield , and its seed cotton yield and lint cotton yield were 264.5 kg/667 m2 and 94.8 kg/667 m2 respectively , being 11.65%and 7.56%higher than those of Suza 201 (CK) separately.The lint rate of Sucai 305 was 35.82%, being 1.35 per-cent lower than that of CK .Its boll was large , and single-boll weight reached 6.3 g, being 0.9 g higher than that of CK .Sucai 305 possessed grade-Ⅱgood synthetic fiber quality , such as fiber length 29.43
