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 multiplication of melon germplasm resources. The method obtains multi-segment atomic bodies as propagules by cutting the branches and tendrils on the parent body of the melon plant. The method is based on rapidly cultivating as many atomic bodies as possible, and only once Reproductive growth is a breeding process of one generation, that is, to complete the rapid breeding of melon germplasm resources. Compared with the existing technology of adding generation and multiplication, 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...
