Abstract

The invention provides a rapid seed selection kit for high-oleic acid peanuts. The research results show that fatty acid dehydrogenase gene (FAD2) is the key gene for controlling the oleic acid traitof peanuts, wherein FAD2 is co-encoded by two non-alleles FAD2A and FAD2B located on different genomes. According to the present invention, based on the genetic gene, multiplex amplification primers respectively for wild and mutant FAD2A gene and FAD2B gene markers are designed by using a colloidal gold test paper strip as a carrier according to the gene sequence conserved region in a peanut high-oleic-acid mutant gene so as to optimize the primer combinations and the reaction system; by using the principle of nucleic acid hybridization, the labeled amplification products are bound with the specific antibody on the colloidal gold test paper strip so as to establish the PCR amplification and colloidal gold lateral flow immunoassay hybridization kit for detecting FAD2A gene and FAD2B gene; and the kit has characteristics of simple operation, strong specificity and high detection sensitivity.

Description

technical field [0001] The invention relates to the field of peanut seed breeding screening, in particular to a high-oleic acid peanut rapid seed selection kit. Background technique [0002] my country is the world's largest peanut producer, consumer and exporter. Peanuts play an important role in my country's national economy. Oleic acid is the main fatty acid in peanut oil, accounting for 39% to 49% of the total peanut fatty acid. It can reduce harmful cholesterol in human body lipid metabolism, but maintain the level of beneficial cholesterol, thereby slowing down atherosclerosis, effectively Prevent the occurrence of cardiovascular and cerebrovascular diseases such as coronary heart disease. In addition, the content of oleic acid is high, the anti-oxidation ability is strong, the product is not easy to oxidative rancidity, the shelf life is long, and the storage resistance is also strong. Therefore, the breeders of the world's main oil crops (soybean, rapeseed, peanut...
