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 rhododendrons with early flowering period and beautiful double petals. The breeding of such varieties began in 2005. The parent material of the hybrid is taken from four-year-old rhododendron 'Hanyin 2' (♀) and rhododendron 'Golden Butterfly' ( ♂). These two kinds of rhododendrons were selected as hybrid parents for the following purposes: 1. 'Golden Butterfly' had an early flowering period; 2. 'Han Yin 2' had beautiful double petals.

[0012] Before hybridization, select the flowers that are about to open and peel off the petals before 10 o'clock in the morning, then completely remove the petals with tweezers, leav...

Abstract

The invention relates to a method for cultivating an early blossoming and multiplicate rhododendron. The method comprises the following steps of: selecting rhododendron plants which do not have plant diseases and insect pests, are robust in growth vigor and are in the early flowering period, and are used as a cross breeding parent, namely Hanyin No.2 (female)* holacanthus septentrionalis (male); selecting flowers which are about to bloom in the first 20 days of April, removing petals at about 10 in the morning, leaving pistil only, pollinating and bagging; removing bags after 7 to 10 days, harvesting fruits when the fruits are yellowed in the middle ten-days of November, and sowing by taking pure peat soil as a sowing matrix in a greenhouse in the middle ten-days of December, watering fully before sowing, and covering a film and keeping moisture until seedlings emerge; after the seedlings grow to form 5 to 6 leaves, transplanting to a 72-mesh tray, recovering the seedlings, pinching once, applying 0.2 percent of Huaduoduo balance fertilizer once every 10 to 15 days; and planting in a nutritional bag after 3 to 4 months, and managing conventionally.

Description

1. Technical field [0001] The invention belongs to the cultivation and selection method of plant hybrids in the field of biotechnology, and in particular relates to a method for cultivating hybrids using Rhododendron plants as parents (Han Yin No. 2 (♀) × Golden Butterfly (♂)). 2. Technical background [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 protection of ...
