| 摘 要： | 为探索甘蔗主要数量性状对产量的影响程度,应用灰色关联度分析方法,对参加2005—2006年区域试验的11个甘蔗新品系的主要数量性状与产量的关联度进行了分析。结果表明:甘蔗主要数量性状与产量之间的关联度由高到低依次为公顷含糖量、茎长、茎径、萌芽率、单茎重、有效茎、分蘖率,说明甘蔗公顷含糖量和茎长是影响甘蔗产量的主要因素,为甘蔗育种提供了重要的理论依据。

| Abstract: | The object was to assess the effect of main quantitative characters of sugarcane on yield. By the method of grey correlative degree analysis, the paper analyzed the correlative degree between main quantitative characters and yield of eleven new sugarcane varieties in 2005--2006. The results showed that the order of the correlative degree of main characters to yield was sugar content per hectare, stalk length, stalk diameter, sprout rate, stalk weight, millable cane, tiller rate. It indicated that sugar content per hectare and stalk length are the main factors which effect the yield of sugarcane. This provided an important theoretic basis for sugarcane breeding. |
