Breeding method for different types of cucumis metuliferus varieties

Abstract

The invention discloses a breeding method for different types of cucumis metuliferus varieties, and relates to the technical field of variety breeding. The method specifically comprises the steps that germplasm to be screened is sown, fruit characters are investigated in the fruit development period, plants with smooth and thorn-free female flower ovaries are thorn-free germplasm, and the germplasm is marked as A germplasm; plants with more juice after fruits are ripe are juicy germplasm and marked as germplasm B; plants with yellow fruit surfaces in the expansion period are yellow fruit germplasm and marked as C germplasm; the germplasm A, the germplasm B and the germplasm C are used as cross parents for variety breeding, and four different types of varieties including combinations of any two of thorn-free fruit characters, juicy fruit characters and yellow fruit characters and aggregation of the three characters are bred. Compared with existing varieties, the thorn-free juicy variety FAB, the thorn-free yellow fruit variety FAC, the yellow fruit juicy variety FBC and the thorn-free yellow fruit juicy variety FABC bred through the method have remarkably different fruit characters, and the blank in the field is filled in the aspect of cucumis metuliferus varieties.

Description

technical field [0001] The invention relates to the technical field of variety selection and breeding, in particular to a method for breeding different types of fire ginseng fruit varieties. Background technique [0002] Fire ginseng fruit (Cucumis metuliferus), also known in China as horned melon, thorn horned melon, African horned cucumber, fire peach, African honeydew melon, Martian fruit, etc., is native to the tropical and subtropical regions of sub-Sahara Africa. It is an annual vine, Monoecious plants, mostly oval fruits, fruit ripening and development period is about 40 days, immature fruit is dark green, and gradually turns to eye-catching yellow or orange red after maturity, there are short and thick thorns on the surface of the fruit, similar to the sea cucumber Therefore, it is named fire ginseng fruit in China. Its pulp is jelly-like, light green, green or emerald green. It is composed of jelly-like seed capsules and contains many seeds. The pulp tastes sour, an...

Problems solved by technology

[0004] At present, the fire ginseng fruits grown in China are all varieties with thorns, dark green skin, and little juice. It takes a long time (more than one month) for the fruit to turn yellow after being picked before being placed on the counter for sale. Dark green or incompletely turned color It is easy to give consumers a feeling of "raw melon", which is not conducive to sales. In addition, when the thorny varieties are picked and packaged, the fruit is easy to stab the fruit surface due to bumps, which reduces the storage and transportation time of the fruit. Therefore, it is necessary to carefully separate the fruit when picking the fruit. Sub-packaging requires a lot of labor; in terms of juice content, the fruit juice content of existing cultivars is relatively low, mainly carp-eating, lacking in juicy varieties, and no reports on the selection and breeding of new varieties of fire cucumbers have been retrieved yet. or patent

To sum up, due to the lag in the breeding of fire cucumber varieties, the variety types are relatively single, which is not conducive to its further development.
