Multi-site molecular marker assistant selection method capable of combining with conventional breeding whole process of wheat

Abstract

The invention relates to a multi-site molecular marker assistant selection method capable of combining with a conventional breeding whole process of wheat. The invention discloses a concrete enforcement method for performing the molecular marker assistant selection technology in the conventional breeding whole process for the first time, the method uses the prerequisite that a molecular marker assistant breeding selection colony is created through a molecule breeding element, the whole breeding process selects genotype through molecular marker, and the method overcomes the disadvantage that conventional breeding selects the genotype according to phenotype.

Description

technical field The invention relates to a multi-site molecular marker-assisted selection method combined with the whole process of conventional wheat breeding, and belongs to the technical field of molecular marker applications. Background technique Breeding of new crop varieties is a scientific innovation that has been carried out along with the development of human civilization. From the random collection activities that started about 10,000 years ago to the large-scale production of traditional agriculture, generations of ancestors have left us a rich variety of farm varieties, which are owned by the germplasm banks of various countries A high proportion of breeding materials is also a precious resource for us to create new varieties. The pea hybridization started by Mendel around 1886 is a symbolic event of modern breeding. In the past 130 years since then, breeders have bred a large number of new crop varieties through sexual hybridization between crop germplasm or c...
