Hybridization method for cherry

Abstract

The invention provides a hybridization method for a cherry. The hybridization method comprises the following steps: collection of pollen; culture of the pollen; storage of the pollen: subpackaging therolled pollen with a plurality of first small bottles, sealing the plurality of first small bottles, forming air vents in the bottlenecks of the plurality of first small bottles, refrigerating the plurality of first small bottles in a refrigerator and adjusting the temperature of the temperature of the refrigerator to a second preset temperature; castration: carrying out castration on bell-like flowers when the flowers of female parents are the bell-like flowers ready to burst; and pollination: based on the desired amount of the pollen, packaging the pollen in the plurality of first small bottles into a plurality of second small bottles, wrapping the bodies of the plurality of second small bottles with paper, then placing the plurality of second small bottles into a foam box filled with ice cubes, dipping the pollen in the plurality of second small bottles with a cotton swab, repeatedly coating the styles of the castrated female parents with the pollen, and carrying out bagging with semi-transparent bags after completion of coating. The method provided by the invention improves the vitality of pollen and enhances artificial hybridization efficiency of the cherry.

Description

technical field [0001] The invention relates to the technical field of cherry cultivation, in particular to a cherry hybridization method. Background technique [0002] There are many types of Chinese cherries, early maturity, self-fertilizing, high fruit setting rate, strong yield, and strong flavor. Cherries are known as "the first of all fruits" among deciduous fruit trees. [0003] Because artificial hybrid breeding can combine the excellent characteristics and characteristics of different cherry species and varieties, break the boundaries between species and species, expand genetic variation, and create new variant types or new species, so in the creation of new cherry germplasm When cultivating varieties and varieties, cross breeding is the most basic means. However, the growth cycle of fruit trees is long, the fruit setting rate of artificial hybrid pollination is low, and the workload is heavy. It is difficult to complete a large amount of artificial hybrid pollinat...

AI Technical Summary

Problems solved by technology

However, the growth cycle of fruit trees is long, the fruit setting rate of artificial hybrid pollination is low, and the workload is heavy. It is difficult to complete a large amount of artificial hybrid pollination during the short flowering period of Chinese cherry, and it is even more difficult to receive mature hybrid seeds.
