Cultivation method of stress-resistant broccoli new variety

Abstract

The invention discloses a cultivation method of a stress-resistant broccoli new variety. The method includes: building callus regeneration systems of different sources; building a broccoli loose embryonic callus induction system; screening an appropriate mutagenesis method; building an efficient regeneration system, and acquiring a regeneration culture medium; acquiring a callus growth culture medium with screening pressure; screening resistant calluses; inducing regenerated buds to obtain regenerated seedlings; further breeding individual plants survived under the screening pressure, and transplanting to a natural environment to perform further selective culture to obtain ideal stress-resistant mutants so as to obtain the stress-resistant broccoli new variety. The method has the advantages a foundation is laid for the cultivation of high-quality vegetable varieties with disease resistance, drought resistance, cold resistance and the like during production, chemical fertilizer use reduction and ecological system restoration are promoted, a new approach is provided for vegetable stress-resistant breeding, vegetable seed resources are enriched, and a foundation is laid for safety vegetable production.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for cultivating new stress-resistant cauliflower varieties. Background technique [0002] Cauliflower, also known as cauliflower, is a widely grown vegetable variety that is universally popular for its nutrient-rich properties. With the development of society, the problem of food safety is becoming more and more serious. Therefore, there is an urgent need for new stress-resistant cauliflower varieties that can greatly reduce the use of pesticides and fertilizers. [0003] Vegetable breeding generally adopts cross-breeding. Due to the limitation of the genetic resources of the species, some new excellent traits cannot be produced. However, the efficiency of general mutation breeding is extremely low, and it is difficult to induce new good traits. Although the gene transformation technology can introduce the target gene into the vegetable genome, but because th...

AI Technical Summary

Problems solved by technology

Disadvantages are: (1) Low efficiency, reason: there are not many individuals with mutations, and a large amount of materials need to be processed

(2) The frequency of beneficial mutations is low, the direction and nature of mutations are difficult to control, and mutation screening is cumbersome

The disadvantages are: (1) No new gene will be produced; (2) The offspring of the hybrid will have trait separation and instability; (3) The breeding process is slow, and the process of obtaining new varieties is long and complicated
