Breeding method of parent and variety of strong-female honey pumpkin

Abstract

The invention relates to a breeding method of a parent and a variety of a strong-female honey pumpkin. The method comprises the following steps of: introducing and collecting pumpkin variety resources with strong-female genes; planting the variety resources, accelerating the purification process, then hybridizing and identifying, screening out a strong-female variety resource to carry out satellite carrying treatment and induce variation so as to obtain a strong-female pumpkin mutant; accelerating the purification process of the mutant, carrying out hybridization and backcross transformation on an obtained strong-female pumpkin material and a high-quality pumpkin material to breed out a strong-female pumpkin patient; and hybridizing the patient with a honey pumpkin patient to breed into a strong-female honey pumpkin variety having the advantages of multiple female flowers, short node distance, easy fruit setting, no sensitivity to sunlight and strong eurytopicity. In the invention, the method for inducing the variation by utilizing the strong-female variety resource to carry out satellite carrying treatment is used for obtaining the strong-female pumpkin mutant, and the strong-female honey pumpkin patient and the variety having the advantages of early maturation, short female flower node distance, easy fruit setting, no sensitivity to sunlight and strong eurytopicity are obtained through hybridization and transformation, thereby the commercial property of the strong-female honey pumpkin is greatly improved, and the economic benefit and the social benefit are increased.

Description

technical field [0001] The invention relates to a breeding method for parents and varieties of pumpkins with strong female honeybodies.

But honey pumpkin also has obvious disadvantages, that is, late maturity, far fruit setting, and sensitivity to sunlight. It is only suitable for cultivation in the south of the Yangtze River in my country, and it is difficult to cultivate successfully in the north of the Yangtze River due to the long sunshine, and its yield is extremely high. Unstable, seriously affecting the benefits of the majority of growers and the enthusiasm for planting
