摘要
以9个陆地棉亲本配置20个杂交组合,对同一亲本的杂交组合平均优势、超亲优势、超标优势进行了分析。结果表明:不同亲本有好的产量性状利用价值,品质性状优势不明显。C2对有效铃、子棉产量有正向作用,C4是一个高产亲本,S2可提高子棉产量、纤维强度和上半部平均长度的表现型值;筛选出了3个综合性状表现优良的组合,提供给生产上应用。
20 hybridized combinations were made by nine upland cotton parents. Average heterosis, over-parent hetero-sis and over-standard heterosis of the combinations which derived from the same one parent were analyzed in this paper. The results indicated that different parents had good yield value, but the quality character advantage was not obvious. C2 had posi-tive effect on effective boll and unginned cotton yield. CA was a high yield parent. S2could improve phenotype value of cotton yield, fiber strength and the first half of the average length. At the same time, the authors have selected three good compre-hensive character combinations.
