对51种南瓜杂交组合(F1)的叶长、叶宽、叶柄长、蔓粗、节间长、第1雌花节位、第1雄花节位、生长势、叶片颜色、叶片形状和嫩果颜色等11个主要农艺性状进行测定,并进行相关分析和聚类分析,以期为南瓜新品种选育提供理论依据。结果表明:南瓜杂交组合(F1)7个主要数量性状都具有较丰富的变异潜力,其中变异潜力最大的是第1雌花节位和第1雄花节位,变异系数分别为20.1%和22.5%;农艺性状相关性分析表明,其农艺性状大都存在极显著或显著差异;利用类平均法在欧氏距离3.72处,供试材料分为4个不同的类型,综合性状最好的是第2类型。
Leaf length, leaf width, petiole length, vine length, internode length, the first female flower node, the first male flower node, growth potential, leaf color, leaf shape and tender fruit color of 51 pumpkin combinations (F1) And other 11 major agronomic traits were determined, and related analysis and cluster analysis, with a view to provide a theoretical basis for the breeding of new pumpkin varieties. The results showed that all the seven major quantitative traits of pumpkin F1 hybrids had rich variation potential. The highest variation potential was the first female flower node and the first male flower node with the variation coefficients of 20.1% and 22.5%, respectively. Agronomic traits correlation analysis showed that most of their agronomic traits exist significant or significant differences; the use of the class average method Euclidean distance 3.72, the test material is divided into four different types, the best comprehensive trait is the second type.
