Breeding method for inducing breeding objective plant variation through plant

Abstract

The invention discloses a breeding method for inducing breeding objective plant variation through a plant. The breeding method includes the following steps that (1) an inducing plant seedling is cultivated, and a bud point or a joint point of the inducing plant seedling is taken as an implantation incision point; (2) a breeding objective plant seedling is selected for standby application; (3) an incision is made at the implantation incision point; (4) the breeding objective plant seedling is implanted in the incision; (5) a breeding objective plant and an inducing plant are fixed, and wet soil covers the breeding objective plant and the inducing plant and is compacted; (6) the plants are maintained in an overshadowed mode and watered every day; (7) after 45 days-60 days, the portions, 5 cm-10 cm away from the incision, on the two sides of the inducing plant are shorn off, and the shorn section of the stem of the inducing plant together with the breeding objective plant and soil around the incision are transplanted to obtain the variant breeding objective plant. The breeding method can achieve mutation breeding between same affinity plants, close affinity plants and far affinity plates, is suitable for most plants, and has the advantages of being high in breeding success rate and induced mutation probability, good in induced mutation combination property, diversified in mutation property, stable, rapid and the like.

Description

technical field [0001] The invention relates to a plant breeding method for inducing and breeding target plant variation, and belongs to the field of plant breeding. Background technique [0002] As the world population continues to grow, so does the demand for food. Therefore, it is urgent to cultivate new varieties of crops to improve the quality and yield of traditional crops. At the same time, with the improvement of living standards, people have higher and higher requirements for quality of life, and they are no longer satisfied with the existing plant varieties. Therefore, plant breeding has become a hot topic for international scholars. [0003] The current common breeding methods include selective breeding, hybrid breeding, mutation breeding (mutation breeding is divided into physical mutation breeding and chemical mutation breeding), biotechnology breeding, etc., but these breeding methods have the following defects to varying degrees: 1.

Problems solved by technology

[0003] The current common breeding methods include selective breeding, hybrid breeding, mutation breeding (mutation breeding is divided into physical mutation breeding and chemical mutation breeding), biotechnology breeding, etc., but these breeding methods have the following defects to varying degrees: 1. The breeding cycle is long, and it usually takes several years or even decades to breed hybrid rice varieties. For example, Xu Zhaoxi spent nearly 20 years cultivating the new Biantiao ginseng variety "Biantiao No. 1" from selection, purification, elimination and strain comparison. Time; 2. The success rate of breeding is low; 3. The predictability of breeding is low. Breeders often breed dozens or even hundreds of hybrid combinations, but the comprehensive performance of new hybrid strains is not good
