【摘要】 采用灰色系统理论和方法对129份中国南瓜F₁代品系的11个主要农艺性状进行了关联分析。结果表明,与单瓜重关联度最大的为第一雌花节位和蔓粗;与可溶性固形物含量关联度较大的是节间长度、瓜横径、蔓粗;而与第一雌花节位关联度最大的是蔓粗;与瓜形指数关联度最大的是瓜纵径。蔓粗可作为南瓜早熟丰产优质育种的相关性选择性状。更多还原

【Abstract】 The association degree between 11 main agronomic characters of 129 hybrid lines were analysed with gray system.The results showed that bigger association degrees were flower and stem diameter to fruit weight.To soluble solid content,the bigger association degrees were length of internodes,fruit diameter and stem diameter.To node of first female flower,the biggest association degree was stem diameter.To fruit shape,the biggest association degree was length of fruit.Therefore,stem diameter can be as an important selective trait to early maturity,high yield and quality in pumpkin breeding.更多还原
