| 摘 要： | 采用单因素遗传设计，研究了１００份黄麻种质资源１１个产量和纤维品质性状的简单相关、偏相关、复相关、典型相关与双重筛选逐步回归分析．结果表明。在不同层次的产量或品质结构中，单株鲜茎重、单株鲜皮重、分枝高、茎粗等主要性状，在产量与品质改良的相关选择和间接选择中都是至关重要的，其所揭示的潜在关联性对黄麻育种有重要的指导意义．

| Abstract: | According to the data of 11 charaters related to fibre yield and qualitywith a single factor ran dom plet design of 100 germplasms in jute (Corchorus czpsularis L),The single corrdlation, Partial correlation,multiple correlation,canonical correlation and dual selective stepwise regression have been studied.The results dowed that the meajor characters of fresh stem weight per plant,fresh bark weight pre plant,per plant,branching height,stem diameter etc,are cxtremely impoftant to the correlative and indirect selection in the improvment of fibre yield and quality.The inherent relativity revealed in this experiment plays an important and instructive role in jute breeding. |
