Breeding method of late-ripeness red-leaf winter peaches

Abstract

The invention discloses a breeding method of late-ripeness red-leaf winter peaches of new varieties of late-ripeness peaches bred out by natural sexual hybridization. The breeding method of late-ripeness red-leaf winter peaches adopts the new variety of bred red-leaf late-ripeness peaches to be naturally hybridized with winter peaches, red snow peaches and original-seed red-leaf peaches to select high-grade seeds, the seeds are sowed in the first third of March, and fruits can be obtained in three years. High-grade single plants of red-leaf late-ripeness winter peaches ripened after the first third and the middle third of November between the Lidong solar term to the Xiaoxue solar term are selected and bred, and after top-grafting tests and blossoming and fruiting observation, and the flower color, the flower diameter and the fruiting rate keep the high-grade characters of the mother plants, the late-ripeness red-leaf winter peaches are obtained. Because the peaches of the invention are bred by natural sexual hybridization according to the late-ripeness heritable principle of red-leaf peaches, winter peaches and red snow peaches, the peaches are big, and have red color, regular shape, thin peel, thick, white and fine pulp, high juice content, fragile and sweet mouth feeling, strong storage durability, high crack resistance and late ripeness. The invention is ripe late, thereby filling the blank of no fresh peach supplied in the period and enriching the fruit market in winter.

Description

Technical field: [0001] The invention relates to a breeding method of a late-maturing red-leaf winter peach which is a new late-maturing peach variety bred through natural sexual crossbreeding. Background technique: [0002] Peach trees are widely planted in North China and the south of my country, and are important tree species for high-quality fruit production. Late peach has also developed rapidly in recent years, but it usually matures in September-October, with an unattractive appearance and a mediocre taste. Generally, there will be no fresh peaches on the market after October. Invention content: [0003] The invention provides a breeding method of a late-maturing red-leaf winter peach which is a new variety of late-maturing peach with a crisp and sweet taste, high sugar content, thin peel and thick pulp bred by natural sexual crossbreeding. It selects and breeds a new variety of Hongye late peach, selects high-quality seeds by natural hybridization with Dongtao, H...
