Embodiment Construction

[0034] The method of the present invention will be further described below through specific examples.

[0035] A method for artificial pollination of Chinese rose kushui, comprising the steps of:

[0036] (1) Flower bud collection: According to the breeding goal, select the plants of rose varieties with excellent traits as the male parent, choose Kushui rose as the female parent, and pick the whole flower bud when the male parent's buds are fully expanded;

[0037] (2) Dry storage of anthers: Open the flower buds of the male parent, take out the fresh anthers and put them on flat and clean sulfuric acid paper, and place them at room temperature for 12-24 hours;

[0038] (3) Pollen collection: After the pollen on the sulfuric acid paper is naturally scattered, put it into a centrifuge tube and seal it;

[0039] (4) Pollination: When the female flower buds are about to bloom, gently open the petals, dip a small amount of male parent pollen with a cotton swab and apply it on the...

Abstract

The invention provides a method for artificial pollination of Chinese Rose Kushui, which mainly includes the following steps: (1) Bud collection: select plants of rose varieties with excellent traits as male parents, select plants of Roses Kushui as female parents, and pick whole flowers Male parent flower buds; (2) Anther drying and preservation: open the harvested male parent flower buds and remove fresh anthers; (3) Pollen collection: collect pollen after the pollen on the anthers are naturally scattered; (4) Pollination : When the female parent flower buds are about to bloom, dip a small amount of male parent pollen and apply it on the female parent flower bud stigma; (5) Bagging: Put the pollination bag on the pollinated female parent flower and seal it; (6) Remove the bag : After waiting for a period of time, take off the pollination bag. Aiming at the research and discovery of the self-incompatibility of Rosa kushui, the present invention proposes a male-free artificial cross-pollination method in which Rosa kushui is used as the female parent. The method is simple to operate, saves time and effort, and has a high breeding success rate.

Description

technical field [0001] The invention belongs to the technical field of plant hybridization and breeding, and relates to a method for artificial pollination of Chinese rose kushui. Background technique [0002] Rose is a deciduous shrub of Rosaceae (Rosa rugosa). It is cultivated in large areas in Kushui, Gansu, Pingyin, Liaoning, Yunnan and Xinjiang in my country.
