Embodiment Construction

[0008] a. Use Chinese wild grapes, strains or hybrids with strong disease resistance as male parents, and collect their pollen 1 to 2 days before flowering.

[0009] b. Dry and grind the collected pollen into a glass bottle, put the bottle in a desiccator and put it in a refrigerator at -20°C for later use.

[0010] c. Use high-quality European seedless grape varieties as the female parent, emasculate the flowers 2 to 3 days before flowering, and then bag the flowers after spraying water.

[0011] d. Pollinate the emasculated flowers with spare pollen from the next day for three consecutive days, and bag them immediately after pollination to form berries.

[0012] e. 40 to 53 days after pollination, first rinse the berries with clean water repeatedly, then rinse with 70% alcohol on an ultra-clean workbench for 20 to 30 seconds, and then soak them in a 0.1% mercury disinfectant solution for 6 to 8 minutes , And then repeatedly rinse with sterile water.

[0013] f. Peel off the ovul...

Abstract

An efficient aggregate method for breeding seedless grap is disclosed, which features that the conventional hybridizing technique, the embryo retriever technique and molecular marker breeding technique are integrated. Its advantages are short breeding period shortened from 7-9 years to 3-4 months, high resistance to disease, high seedless percentage, and high quality of grape.

Description

Technical field [0001] The invention relates to plant breeding technology, in particular to a high-efficiency polymerization breeding method for disease-resistant seedless grapes. Background technique [0002] As a worldwide fruit, grapes rank second in the world in terms of planting area and output. The seedless trait is a special trait symbol in the commercial production of grapes. In developed countries and regions, the output of seedless grapes has accounted for more than 60% of the total grape production. In my country, with the increase in market demand, the cultivation area of ​​seedless grapes is also on the rise. However, the lag in seedless grape breeding technology and the lack of new varieties have seriously hindered the improvement of seedless grape yield and quality. At present, the breeding of seedless grapes in the world generally adopts traditional conventional cross breeding technology, that is, the seedless varieties are used as the fem...
