Abstract

A two-phase culture medium for improving anucleate antiviral glucose embryo crash breeding efficiency and its production are disclosed. The procedure is carried out by preparing liquid-phase culture medium and solid-phase culture medium proportionally, using liquid to kill bacterium at high-pressure, pouring it into solid-phase culturing medium supernatant and preparing solid-phase culture medium. It has better anucleate antiviral glucose embryo development rate and breeding rate.

Description

technical field [0001] The invention relates to grape breeding technology, in particular to a dual-phase culture medium and a preparation method for improving the efficiency of disease-resistant seedless grape embryo rescue breeding, and belongs to the field of biotechnology. Background technique [0002] Grapes have become one of the main fruits that people love because of their rich nutrients and unique health functions. More than 80% of the table grapes in the United States are seedless varieties. At the same time, in the world, the widespread occurrence and prevalence of grape fungal diseases have also been concerned by breeding scientists. Therefore, cultivating high-quality, disease-resistant seedless grape varieties has become one of the common goals of grape breeding in various countries in the world. The breeding method of disease-resistant seedless grapes is an important link to provide high-quality varieties for production. Since the A...
