Method for obtaining tartary buckwheat seeds easy to shell

Abstract

The invention relates to a method for obtaining tartary buckwheat seeds easy to shell and belongs to the technical field of genetic seed breeding of crops. According to the provided method, a chemicalmutagenesis method is adopted to obtain the high-quality tartary buckwheat seeds. The adopted technical scheme includes the steps that a, ethylmethane sulfonate is utilized to process 5,000 ethylmethane sulfonate (Heifeng No.1) seeds, and the seeds are soaked in an EMS solution for 8-10 hours and stirred several times during soaking; then, the solution is poured out carefully, sodium thiosulfateis adopted for neutralizing the EMS solution, distilled water is adopted for flushing several times, and the seeds are placed in a fuming cupboard for airing for preparation of sowing; b, the processed seeds are sown in land which is ploughed previously, wherein if the statistic fatality rate of the sown seeds reaches 30-50%, mutagenesis is effective; c, M1-generation mutants are obtained from each single plant in order to harvest potential available mutants; d, after screening and seed baking, it is found out that shells of seeds of three single plants are broken, after continuous planting ofM2-M5 generations, three plant systems with stable gene expression are obtained, and more than 100 single plants are obtained. The method has significant meaning on diversification of tartary buckwheat seed resources, shortening of a traditional seed breeding process and boosting of tartary buckwheat seed breeding work.

Description

Technical field [0001] The invention relates to a method for obtaining germplasm of easy-husking tartary buckwheat, belonging to the technical field of crop genetic breeding. Background technique [0002] Tartary buckwheat is a kind of medicine and food. Its grains are rich in a variety of amino acids, vitamins and minerals that are beneficial to the human body. It is an auxiliary treatment food for diabetes. It contains rich flavonoids, especially rutin, which protects the cardiovascular and cerebrovascular, scavenging free radicals, and antioxidants. , Anti-aging has excellent effects. With the introduction of the concept of healthy China, more and more people are paying attention to healthy diet, and the rich nutritional value of tartary buckwheat and its rare health care functions are increasingly being valued. [0003] The most important of tartary buckwheat products are tartary buckwheat tea and tartary buckwheat flour. All these products need to dehull the tartary buckwhe...

Problems solved by technology

The hulling process should go through low-temperature soaking, drying, steaming, and frying. After frying, spray cold water quickly, use the difference in expansion coefficient between buckwheat hulls and kernels to promote the separation of buckwheat hulls and kernels, and then use a centrifugal device to remove the shells. This process is very cumbersome and time-consuming
