High-efficiency polymerization method for apple cross breeding

Abstract

The invention discloses a high-efficiency polymerization method for apple cross breeding. The cross breeding is the most important and most effective way of the breeding of the apples, but the evaluation and the screening of crossbreed seedlings and cross breeding fruits take a lot of work and labors, steps of the cross breeding method are complicated, and the improper technology of each step can cause the failure of the breeding. The breeding period of the apples is long and needs at least 20 years from the cross breeding to the new species selecting and breeding. The method optimizes the key steps of the cross breeding of the apples and overcomes the defects of the conventional breeding method. The method adopts the technical schemes of anther collection; artificial cross breeding; cross breeding management; cross breeding seed collection and pregermination; cross breeding young seedling management; early selection of cross breeding seedlings; primary selection and reselection; and excellent series area demonstration. Compared with the conventional method, the high-efficiency polymerization method specifically and effectively selects indexes, can shorten the breeding period of the apples by 3-4 years and save the breeding cost of the apples by 15-20 percent, and the method system achieves the international advanced level.

Description

technical field [0001] The invention relates to a high-efficiency polymerization method for apple cross-breeding, which optimizes the key steps of apple cross-breeding, obtains an optimized technical method system, improves the efficiency of apple cross-breeding, and belongs to the field of agricultural biotechnology. Background technique [0002] Apple is an important fruit worldwide, one of the four major fruits in the world, and also the fruit tree species with the largest cultivated area and output in northern my country. The breeding of new apple varieties is the basis of apple industrialization. With the continuous development of the apple industry, the breeding of apple varieties with independent intellectual property rights has attracted more and more attention from major apple cultivation countries. Although the cultivation of new apple varieties can adopt multiple approaches and methods such as hybrid breeding, seed selection, bud mutation selection, radiation muta...

Problems solved by technology

Over the years, in order to shorten the breeding cycle of fruit trees and improve the breeding efficiency, domestic and foreign apple breeding units have done a lot of active exploration and practice, but this problem has not been really solved in the practical application of breeding. Breeding objectives have not yet established a set of easy-to-operate and effective selection methods and selection indicators
