A kind of breeding method of radish rich in anthocyanins

Abstract

The invention relates to a crop breeding method, in particular to a radish breeding method, belonging to the technical field of plant breeding and cultivation. The breeding method is characterized in that Kexing red-core and red-skin radishes are taken as female parents, wherein the Kexing red-core and red-skin radishes come from Sichuan province, have a moderate maturity period and upright leaf bunches, contain high-content anthocyanin, are high-yield, disease-resistant, red-skinned and have red flesh and long cylindrical flesh roots; Hengfeng transparent-core red radishes as male parents, wherein the Hengfeng transparent-core red radishes come from Chongqing, have a moderate maturity period and half upright leaf bunches, contain high-content anthocyanin, are heat-resistant and red-skinned and have red flesh, long cylindrical flesh roots and slightly larger lower parts; and the female parents are hybridized with the male parents to obtain intervarietal hybrids F1, and the intervarietal hybrids F1 are continuously self-bred to obtain a new high-quality, high-yield, high-anthocyanin-content and disease-resistant red-skin and red-core radish variety, i.e. Yanzhi No.1. The radish breeding method has the beneficial effects that the breeding efficiency is high, the obtained products are suitable for the extraction processing of anthocyanin and the problem existing in the raw material supply in the anthocyanin extraction processing industry is solved.

Description

technical field [0001] The invention relates to a method for breeding crops, in particular to a method for breeding radish, and belongs to the technical field of plant breeding and cultivation. Background technique [0002] The price of anthocyanin pigments in the international market is relatively high. In its processing industry, anthocyanin pigments using radish as raw material are very stable, and the cost of raw materials is low and the quantity is sufficient. Therefore, radish anthocyanins have a very strong market Competitiveness. There is a long history of planting radishes in rural areas of our country. Taking into account the local land characteristics, landforms and climate, planting high value-added radishes for anthocyanin extraction is one of the important ways to increase the income of local farmers. [0003] According to the applicant's knowledge, since the collection of domestic radish varieties rich in anthocyanins has just begun, the breeding of special r...

Problems solved by technology

[0003] According to the applicant's knowledge, since the collection of domestic radish varieties rich in anthocyanins has just begun, the breeding of special radish varieties suitable for extracting anthocyanins started relatively late, with few varieties, low yield, low anthocyanin content, and mature period Consistent, concentrated in the market, mixed leaf color, leaf shape, root shape, early shoots, bran core and other degradation phenomena in the population, and there are regional differences. Therefore, it is extremely necessary to strengthen research on breeding, especially those suitable for geographical climate in sandy soil areas. High-quality anthocyanin-specific radish varieties need further research and development to solve the problem of raw material supply in the extraction of anthocyanin processing industry
