Corn breeding method capable of carrying out cold plasma treatment

Abstract

The invention relates to a corn breeding method capable of carrying out cold plasma treatment. The method comprises the following steps: carrying out cold plasma treatment on seeds of a core variety; carrying out generation increment breeding on the seeds subjected to cold plasma treatment, carrying out assistant breeding by molecular marking and isozyme identification, and carrying out single plant selection so as to select a selfing line with target characters and excellent variation; carrying out selfing purification and rejuvenation on the selfing line with excellent variation, and then carrying out hybridized combination to obtain good corn seeds. According to the method, the three technologies including molecular marking, isozyme identification and heterosis utilization are combined after the cold plasma treatment, so that the corn breeding period is further shortened, the breeding speed is accelerated, and a better new corn variety can be obtained by breeding; the corn breeding method and means have advancement.

Description

technical field [0001] The invention relates to a corn breeding method, in particular to a cold plasma treatment corn breeding method, which belongs to the field of agriculture. Background technique [0002] Traditional maize breeding has indeed made great achievements in the past few decades. However, due to the limitations of long breeding time and low efficiency, it is only based on experience and relatively blind, resulting in low-level repetition and serious homogeneity. At present, traditional maize breeding Breeding encountered a great bottleneck, or even stagnation. If you want to have higher achievements in corn breeding, you must rely on modern science and technology. However, the current breakthrough genetically modified breeding method has aroused fierce debates around the world. It is believed that genetically modified crops have great potential dangers and may pose a threat to human health and the human living environment. With the development of space techno...

However, the current breakthrough genetically modified breeding method has aroused fierce debates around the world. It is believed that genetically modified crops have great potential dangers and may pose a threat to human health and the human living environment

With the development of space technology, it has become a new breeding method to use the mutagenesis of plant seeds produced by special environmental conditions in space to carry out breeding methods. However, space breeding is a new method of artificial mutation breeding. The occurrence of mutations is random, and targeted mutagenesis is not possible at present. The success rate of space breeding will vary greatly with different species, and the cost of space breeding is quite high, which cannot be afforded by ordinary units and individuals.
