Method for increasing capsorubin content in capsicums

Abstract

The invention relates to a method used for increasing capsorubin content in capsicums. Breeding methods of plant new varieties are plenty, and mainly comprise natural variation, crossbreeding, space breeding and ion beam implantation mutation breeding, but the frequency of the natural mutation is low. The method of the invention comprises following steps: burying capsicum seeds vertically in the flower mud of a culture dish at equal intervals with germs upwards and exposed; placing the prepared capsicum seed culture dish in an ion beam implantation vacuum system with the culture dish facing an ion source; reducing the pressure of the vacuum system to 10 to 4 Pa; turning on the ion radiation source, adjusting technological parameters of ion radiation; and performing ion radiation, turning off the ion radiation when ion radiation is complete, inflating the vaccum system, and taking the capsicum seeds out of the vaccum system for culturing. Beneficial effects of the ion beam implantation mutation breeding method of the invention are that: the technological parameters, ion energy and implantation dosage are convenient to adjust and control, adaptability is high, variation frequency is high, variation spectrum is wide, and stabilization is high.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a method for increasing the content of capsanthin. Background technique [0002] Pepper is an important vegetable crop. In addition to being used as a condiment, it also has high nutritional value. It is rich in carbohydrates, protein, three vitamins, calcium, phosphorus, and iron minerals needed by the human body, and is needed by the human body. 15 amino acids. With the improvement of people's living standards, people are very concerned about the capsaicin and red pigment of capsicum, that is, the taste and ornamental properties of capsicum. At present, there are a large number of documents mentioning how to improve the capsicum extracted from capsicum by various methods, but little attention is paid to how to increase the capsicum content of capsicum itself, that is, to increase the content of capsicum in capsicum when cultivating new varieties of cap...

Problems solved by technology

However, the frequency of natural variation is low, only one in tens of thousands, or even one in hundreds of thousands; hybrid breeding can bring together two or more excellent traits, but this method will not produce new genes, and the hybrid offspring will Separation of traits occurs, and the breeding process is slow and complicated; space breeding uses the mutagenic effect of the special space environment (high vacuum, cosmic high-energy ion radiation, cosmic magnetic field, and high cleanliness) that cannot be simulated on the ground to mutate the seeds and then reproduce them. Returning to the ground to select new seeds, new materials, and cultivate new varieties of new crop breeding technology has the characteristics of many beneficial variations, large changes, fast stability, high yield, high quality, early maturity, and strong disease resistance, but the cost is high. Inconvenient to operate; while the ion implantation mutagenesis breeding method also has the advantages of space breeding, including vacuum environment, ion interaction, etc. The difference is that there is no weight loss, but this method is low in cost, easy to operate, and easy to industrialize
