Peanut breeding method by cold plasma treatment

Abstract

The invention discloses a peanut breeding method by cold plasma treatment. The method comprises the following steps: (1) carrying out cold plasma treatment on a to-be-treated peanut raw material to obtain a material after cold plasma treatment; and (2) breeding peanuts with target characters from the material after cold plasma treatment. The method disclosed by the invention carries out the cold plasma treatment on peanut seeds, so that the ability of the peanut seeds is remarkably improved with the following characteristics: the germinating ability of the seeds is improved; the plant height is decreased; the main root length is increased; fibrous root length is increased; the fresh weight of hundreds of seedlings is increased; the first lateral branch is prolonged; the total branching number is increased; the full fruit quantity of a single plant is increased; the flat fruit quantity of a single plant is reduced; the weight of hundreds of peanuts with shells is increased; the 100-kernel weight is increased; the kernel yield is increased; and the output is increased. The peanut breeding method disclosed by the invention breaks through the defect of low-level redundancy and severe homogenization in conventional breeding, potential dangers in transgenic breeding and huge economic input of space breeding, can shorten the breeding period and has advancement in breeding method and means.

Description

technical field [0001] The invention relates to a peanut seeding method, in particular to a peanut seeding method using cold plasma treatment technology, and belongs to the field of agricultural technology. Background technique [0002] Peanut, formerly known as groundnut (scientific name: Arachis hypogaea Linn.), belongs to Rosaceae, leguminous annual herb, stem erect or prostrate, 30-80 cm long, wing petals and keel petals are separated, pods are 2-5 cm long and 1.5 cm wide. ~1.3 cm, swelling, thick pods, flowering and fruiting period from June to August. Peanut is an important crop in our country, and the breeding of peanut has always been one of the research hotspots. [0003] Traditional peanut breeding has made great achievements in the past few decades, but due to the limitations of long breeding time and low efficiency, it is relatively blind based on experience, resulting in low-level repetition and serious homogeneity. Breeding encountered a great bottleneck, or ...

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. , difficult to popularize
