Problems solved by technology

[0003] The breeding cycle of perennial fruit tree crops is long, takes up a lot of land, and requires a lot of investment, while the process of breeding functional components of apples is a process of comprehensive evaluation and selection of multiple indicators, involving various traits such as appearance, fresh food quality, and content of functional components. The traditional selection method of several single indicators is difficult to effectively select functional apples

Abstract

The invention discloses an apple breeding method. The method comprises the following steps: respectively conveying pollen of red-flesh and crisp-flesh strains to a castrated apple variety having excellent comprehensive characters to obtain backcross seeds; taking helium gas as a working medium, and performing non-ionizing radiation treatment on the seeds in a vacuum closed environment; sequentially performing seed soaking and seed priming treatment; building a seedling raising bed composed of a plurality of 8*10cm seedling raising troughs in a greenhouse, and filling self-made planting soil in each seedling raising trough; after the filling operation is completed, gently pressing the primed seeds into the planting soil according to a standard that the seeds are just covered by mud, wherein two seeds are sown in each seedling raising trough; and the seed sowing operation is completed, covering a semitransparent film on the seedling raising bed, and perforating the covered semitransparent film corresponding to the places where the seeds are sown and around the places where the seeds are sown. According to the invention, the breeding period is shortened, and the germination rate and transplanting survival rate are greatly improved, thereby enabling the population yield to reach the maximum and increasing the fine fruit rate.

Description

technical field [0001] The invention relates to the field of apple breeding, in particular to an apple breeding method. Background technique [0002] Xinjiang wild apple (or Malus sieversii (Lebed.) Roem.) is the ancestor species of cultivated apple in the world. The contents of functional components such as chlorogenic acid, catechin and Ca are more than three times that of the 'Red Star' apple variety. Among the 177 detected aroma components, 90 components such as acetals and lactones are Xinjiang wild apples. Proprietary ingredients. However, due to farmland reclamation and other reasons, wild apple resources in Xinjiang are being severely damaged and are on the verge of extinction. Therefore, the effective use of wild apples in Xinjiang to carry out apple hybrid breeding can not only expand the genetic diversity of cultivated apple varieties, cultivate new functional apple varieties, but also contribute to the scientific protection and sustainable utilization of wild a...
