Breeding method for one-generation hybrid thick peel mushmelon

Abstract

A method for culturing the first-generation hybridized seed of thick-pulp muskmelon features that the raw materials taken from remote regions in different ecotopes are chosen for continuous selfing at same time in different regions by different cultivating methods (great plastic hotshed or covering ground by plastic film), and two complementary parent self-lines with high resistance, adaptabilityand economy benefit are chosen to hybridize, obtaining the first-generation hybridized varieties "Ganmibao" and "Xingmibao". Their advantages include high anticontravariant nature, bigger melon body,beautiful appearance, and high yield and sweetness.

Description

technical field [0001] The invention relates to the field of utilization of heterosis of muskmelon, in particular to a breeding method of the first-generation hybrid of muskmelon. Background technique [0002] Thick-skinned muskmelon has strict requirements on the cultivation environment, and likes the ecological conditions of high temperature, dryness, strong light, and large temperature difference between day and night. It is most suitable for cultivation in some areas of Xinjiang, Gansu and Inner Mongolia in Northwest my country. Due to the strong regional characteristics of muskmelon cultivars, the commercial properties of fruits grown in different places are obviously worse. Cantaloupe varieties can only be fully expressed in Xinjiang if they are planted. The main commercial properties are large melons and beautiful appearance. Good storage and transportation, single melon weighs about 4 kg, long oval shape, full reticulated fruit surface, thick flesh, crisp texture, g...

Problems solved by technology

In Gansu and Inner Mongolia, Bailan melon and Huanghe honey are the main varieties. Their commercial properties are mainly spherical or nearly round, with light skin or a small amount of netting. The weight of a single melon is about 2 kg, and the soluble solid content is 12%. Left and right, soft flesh, medium storage and transportation, better planting adaptability in "moving east", but the commodity traits have declined. Therefore, it is difficult for Xinjiang Hami melon varieties and Gansu varieties to be directly used in different places

At present, the thick-skinned melons successfully planted in Northeast China, North China and some southern regions are all small-fruited cantaloupe varieties. The fruits are mostly spherical, with a single melon weighing about 0.8 kg, soft flesh, and a refractive sugar content of 13-15%, which is poor in storage and transportation

In the method of cultivating new varieties, it is still carried out according to the general hybrid breeding method at present. The original materials are arranged to be planted and observed in the same cultivation mode in the same place, and the line selection is carried out. It is difficult to fully express its excellent seed properties, so that the selection of parental materials is limited, and the adaptive selection of parental materials is virtually ignored, resulting in poor adaptability of the bred new varieties and narrow areas suitable for cultivation
