摘　　要：对18个陆地常规非抗虫棉品种铃壳重与7个产量性状、6个纤维品质性状进行了相关性分析与聚类分析。结果表明,铃壳重与全铃重呈极显著正相关,与单铃子棉重、衣指、整齐度指数呈显著正相关,与伸长率呈显著负相关,与皮棉产量、纤维品质综合分值无显著相关。铃壳重较轻与光合产物较多的提供给棉子和纤维的生长发育、促进子棉产量的提高和纤维品质的改善有关。Correlation between cotton boll shell weight and 7 yield traits and 6 quality traits was analyzed with 18 non - Bt upland cotton varieties as materials, and the cluster analysis was made. The results showed that the extreme significant positive correlation existed between cotton boll shell weight and cotton boll weight, significant positive correlation existed between cotton boll shell weight and seed cotton weight per boll, lint index and uniformity index, and significant negative correlation existed between cotton boll shell weight and elongation percentage. And there was no significant correlation be-tween cotton boll shell weight and lint yield and fiber quality synthesis score. The lighter cotton boll shell weight was ad-vantageous to improvement of lint yield and fiber quality.
