Abstract

The invention discloses a breeding method of a high-quality high-output pumpkin new variety, comprising the following steps: selecting a parent source, a sowing time, a pollination and fruit setting time, and a seed collecting and seed taking time, wherein American pumpkin material is used as a female parent, Indian pumpkin material is used as a male parent, the American pumpkin material and the Indian pumpkin material are hybridized, selfing separation and screening are performed on the filial generation, the filial generation with different plant types, stem and vine colors, fruit colors andfruit types are selected as the F1 generation, selfing breeding is performed until reaching F5 generation, so as to obtain a strain with steady and consistent phenotype and excellent comprehensive characters, and then variety identification is performed, so as to obtain the pumpkin new variety. According to the breeding method provided by the invention, the bred pumpkin new variety not only has the characteristics of being straight in short vines, easy in maturing and moderate in pumpkin type of American pumpkin material, but also has the characteristics of powdery, glutinous and sweet flavorquality of the Indian pumpkin material, and can resist weak light and has the characteristics of parthenocarpy, high fruit setting rate, good fruit quality, strong growth vigor, high output, and excellent appearance quality and eating quality in comparison with general American pumpkin varies.
