Embodiment Construction

[0009] The following examples of the present invention are used to further illustrate the substantive content of the present invention, but the content of the present invention is not limited thereto.

[0010] Variety breeding method (breeding procedure and instructions on using parental breeding materials):

[0011] The goal of cultivating varieties is to select alpine rhododendrons with aroma, and the breeding of such varieties began in 2007. The parent material of the hybrid is taken from the 'Amethyst' which is widely used in production, has good adaptability everywhere, grows vigorously, and is free from diseases and insect pests. and 'big white flower' These two kinds of rhododendrons were selected as hybrid parents based on the following purposes: 1. 'Amethyst' has a beautiful flower shape and plant type; 2. 'Big White Flower' rhododendron has an aromatic smell.

[0012] Before hybridization, select the flowers that are about to open and peel off the petals before 1...

Abstract

The invention discloses a method for cultivating aromatic alpine rhododendron. The method comprises the following steps: selecting a rhododendron plant amethyst (female) which is not suffering from pest and disease damage, is strong in growth vigor and is in an early flowering period and rhododendron decorum (male) as cross parents, selecting just colored flowers of the rhododendron decorum in the early of middle of April, removing petals and stamens at about 10a.m, only remaining pistils, pollinating the pistils with pollen of the amethyst and bagging, removing the capped bags within 7-10 days, picking fruits when the fruits turn yellow in the middle of November, and sowing the fruit in a greenhouse in the middle of December; by taking pure peat soil as a sowing medium, thoroughly watering the soil before seeding, cover the soil with a film and moisturizing until seedlings come out; transplanting the seedlings to a 50-mesh tray when 5-6 leaves of the seedlings grow, recovering the seedlings, pinching, and fertilizing the seedlings with a 0.2 percent Huaduoduo balance fertilizer once every 10-15 days; and planting the seedlings in nutrition bags after 3-4 months, and performing regular management.

Description

technical field [0001] The invention belongs to the cultivation and selection method of plant hybrids in the field of biotechnology, and specifically relates to a plant of the genus Rhododendron as a parent ('Amethyst' × Rhododendron 'Big White Flower' ) methods of breeding hybrids. Background technique [0002] Rhododendron (Rhododendron), as a famous ornamental plant, is widely planted all over the world. my country's Yunnan, Tibet, and Sichuan areas are the birthplace and modern distribution center of Rhododendron in the world, but most of the Rhododendron species cultivated in a large area in my country rely on imports, which is extremely inconsistent with my country's rich resources of Rhododendron. [0003] Hybrid breeding is the main technical method for the selection and breeding of new Rhododendron species. In recent years, many botanists have carried out the introduction and hybrid breeding of Rhododendron extensively around the world to facilitate the protecti...
