Embodiment

[0040] In a certain year, 1 seed of melon resources was collected abroad. In Jilin Province, the present invention was applied to multiply, and the rooting and transplanting of vines were repeated twice, and 124 fruit bodies were obtained. The average single melon harvested seeds was about 320, and the seeds were harvested in total. About 118,000 grains, one generation meets the quantity requirement, and the multiplication of this resource is completed.

[0041] The specific implementation process is as follows:

[0042] 1. Cultivation of the original muskmelon resource plant mother body

[0043] (1) Female seedlings: After the seeds are sterilized, they are sown in a nutrient bowl with a diameter of 7.2 cm and a height of 7.2 cm. The ratio of substrate garden soil:compost:river sand:plant ash is 4:4:2:1.

[0044] (2) Maternal transplanting: When the seedlings are 30 days old, grow to 4 leaves and 1 heart, transplant to the greenhouse, 5 leaves and 1 heart, topping, leave 4 b...

Abstract

The invention discloses a method for rapid expanding propagation of melon germplasm resources. According to the method, a plurality of sections of original daughters are obtained as propagules by cutting out the branches on the maternal body of a melon plant, and on the basis of rapidly culturing as many original daughters as possible, the rapid breeding of the melon germplasm resources is completed simply through a process of once reproductive growth and one generation of breeding. Compared with the prior art of multiple generation expanding propagation, the risk of biological mixing and mechanical mixing is significantly reduced, the breeding cost is greatly reduced, and the breeding time is shortened.

Description

technical field [0001] The invention relates to the technical field of crop breeding, and in particular to a method for rapidly multiplying melon germplasm resources. Background technique [0002] Melon (Cucumis melo L.) is also known as muskmelon, Hami melon, etc. It is an annual vine herb of Cucurbitaceae. Stems and branches are ribbed. Tendrils slender, simple, puberulent. Petiole long with grooves and short bristles; leaf blade thick papery, rough above, covered with white scabrous bristles. Unisexual or perfect flowers. Female flowers (or complete flowers), andromonoecious. Male flowers: several in clusters in leaf axils; pedicel slender; corolla yellow; female flower (or full flower): solitary, pedicel rough, pilose; ovary oblong. The shape and color of the fruit vary from variety to variety, usually spherical or oblong, with smooth skin, longitudinal grooves, or stripes, white, yellow or green flesh, with a sweet taste; dirty white or yellowish-white seeds, oval...
