| 摘 要： | 采用加性-显性及其与环境互作的遗传模型,对10个海岛棉亲本的F1的24个组合的株型性状及产量进行了遗传方差分量的分解和成对性状间遗传效应的相关分析.结果表明:株高、茎粗、果枝数、节数显性相关为0,主要受加性相关的影响.生育期性状主要存在显性相关,产量性状的加性相关和显性相关均较小,其余相关都达到极显著水平.大部分性状的广义遗传率和狭义遗传率达到极显著水平.

| Abstract: | Using 10 different cultivars of sea-island cotton to form 24 combinations to analyze the co-relationship of different characteristics.The results showed that plant height,stem width and number of fruit branches were additively related.Growth mainly is dominantly related.Yield characteristics mainly additive and dominant co-related.The results were useful for sea-island cotton breeding. |
