A kind of breeding method of new variety of golden melon with seven treasures and ten tendons

Abstract

The invention provides a breeding method of a seven-treasure and ten-rib golden melon new variety. The method is characterized by comprising the following steps: selecting female flowers above the fifth section site of a fruiting cane of one type of seven-treasure and ten-rib golden melon plant system as a female parent, and selecting male flowers of another type of seven-treasure and ten-rib golden melon plant system as a male parent; carrying out hybridization, and harvesting fruits after successfully hybridized fruits are ripe; cutting the harvested fruits for taking out seeds, washing clean and then drying in the sun; separately sowing the seeds obtained by hybridization for planting in the second year; after entering the blooming and fruit-bearing stage, carrying out back-crossing; after the fruits are ripe, determining the characters, eliminating the low-quality fruits, and preserving the high-quality fruits; separately sowing the seeds, obtained in the previous year, of the plant system, and selecting excellent plant systems, which grow strongly, are high in disease resistance and fruit setting percentage, have cylindrical to elliptical shapes, are golden in skin color and have ten white cluster ribs, in a field as a new variety line. The breeding method improves the purity of the seven-treasure and ten-rib golden melons by applying the technologies such as hybridization, back-crossing, heterozygosity prevention and homozygote preservation, thus improving the yield and quality condition of the variety.

Description

technical field [0001] The invention relates to a technique for selecting and breeding new varieties of golden melon with seven treasures and ten tendons, which belongs to the technique for selecting and breeding crops. Background technique [0002] Qibao "Ten Tiao Jin" golden melon is a local variety in Minhang District, Shanghai, and one of the four famous and high-quality melon varieties in Shanghai. Sweet, famous in Shanghai for more than a hundred years, deeply loved by the public. However, due to long-term neglect of the preservation and innovation of germplasm resources, the Qibao Shitiaojin Golden Melon is almost on the verge of extinction. And because of the long-term planting, it causes natural mixing, reduces the purity, and seriously degrades the species, which reduces the yield and quality of the species. In order to effectively protect and rescue the local characteristic variety resources in Minhang District, and revive the Qibao Golden Melon, which has been ...
