Embodiment 1

[0025] A method for improving the quantity and quality of muskmelon hybrid seeds, comprising the following steps:

[0026] (1) Cultivation mode: The full-coverage cultivation mode is adopted in the facility greenhouse, that is, the surface of the ridges and the inter-ridges are covered with plastic film and sterilized dry straw, respectively, and the seedlings are raised in late February, transplanted in early April, and hybridized in early May;

[0027] (2) Selection of hybrid melons: When the seedlings grow to 5 true leaves, pick the heart, leave 2 side vines, and use 4-6 female flowers on the side vines for cross-pollination;

[0028] (3) Pollination: emasculate the female flowers that open the next day, bag the male flowers that open the next day, collect fresh pollen at 8-10 am the next day for pollination, and repeat the pollination once the next day. Spray a small amount of 0.1% boric acid solution on the stigma after the second pollination, and then bag it;

[0029] (...

Abstract

The invention discloses a method for increasing the quantities of hybrid seeds of thick-rind muskmelons and improving the quality of the hybrid seeds. The method includes adopting whole-cover cultivation modes in facility greenhouses, pinching each seedling when five true leaves grow on the seedling, reserving two lateral vines in each seedling and carrying out hybrid pollination on 4-6 female flowers of each lateral vine twice; spraying a small quantity of 0.1% boric acid solution on stigmas every time after the female flowers are pollinated, reserving 3-4 leaves for topping at the rear of each female flower and only reserving a growth point on each whole plant; spraying 200 mg / L gibberellin on hybrid young muskmelons in 24 h after secondary pollination is carried out. The method has the advantages that the key technical problem that seeds of thick-rind muskmelons cannot be obtained by means of hybridization or selfing or the seeds are unfilled can be solved by the aid of the method, the quantities of the hybrid seeds of the thick-rind muskmelons can be increased, the quality of the hybrid seeds can be improved, the thick-rind muskmelon breeding efficiency can be improved, and technical support can be provided for selectively breeding novel varieties of high-quality muskmelons.

Description

technical field [0001] The invention relates to a technical method of hybrid breeding, in particular to a method for improving the quantity and quality of hybrid muskmelon seeds, and belongs to the technical field of plant breeding. Background technique [0002] melon( Cucumis melo L.), also known as muskmelon, fruit melon, sweet melon, etc., is an annual vine herb of Cucurbitaceae Melon. my country has rich resources of melon varieties and various cultivation methods. In cultivated melons, due to different origins and ecological characteristics, China usually divides melons into two types: thick-skinned melons and thin-skinned melons. With the development of protected horticulture, since the 1970s, the research on the eastward and southward migration of thick-skinned muskmelon has been successively launched in China, and great progress has been made in protected cultivation technology and research on new variety selection. During the breeding process of new muskmelon vari...
