Embodiment 1

[0013] Introduced and collected 11 Chinese pumpkin variety resources with strong female genes at home and abroad. After 3 years and 5 generations of purification work, we obtained 2 pumpkin varieties with good comprehensive characteristics, long gourd shape, many female flowers, and easy fruit setting in the spring of 2006. Strong female Chinese pumpkins, numbered as Chinese pumpkin No. 1 and No. 2. In August 2006, 50 seeds were taken from each of the seeds for satellite carrying treatment. All the treated seeds were planted in Hainan in 2006. Among them, a growing plant was found in No. 1. The mutant strain with strong and obviously larger fruit type is numbered S096. After 2 years and 4 generations of directional breeding, a stable single-line S096-1-1-1-1 was obtained. Its characteristics are: stable plant growth, medium-sized leaves, waxy leaves, insensitive to sunlight, main vines The first female flower is at 3-4 nodes, and 1-2 more are born at intervals of 1-2 nodes. Th...

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. Background technique [0002] In recent years, with the development of my country's economy, people's living standards have been continuously improved, and people's pursuit of health has become higher and higher. As a "natural green health food", pumpkin has gradually been recognized by people, and the consumption of pumpkin has increased year by year. The honey-ben pumpkin with strong resistance, easy cultivation and high quality is popular in the market, and the cultivation area is expanding year by year, and has now grown to an annual cultivation area of ​​more than 1 million mu. 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 nor...
