Embodiment 1

[0029] Cultivation and cultivation of 'Guiyun' begonia (B.'Guiyun'):

[0030] 1. Materials and genealogy

[0031] Begonia (Begonia L.), Curly Begonia (B.cirrosa L.B.Smith)×F of Guangxi Begonia (B.guangxiensis C.Y.Wu) 1 generation.

[0032] Among the breeding parents adopted, Curly Begonia (B.cirrosa L.B.Smith) was introduced from Napo County in the west of Guangxi and Funing County in the southeast of Yunnan, and B. guangxiensis C.Y.Wu was introduced from Du’an County in the west of Guangxi. The original materials are flowering plants that have been domesticated for many years in the collection, conservation and cultivation of begonia germplasm resources of the Kunming Institute of Botany, Chinese Academy of Sciences.

[0033] 2. Breeding method of 'Guiyun' begonia (B.'Guiyun')

[0034] Using Curly Begonia (B.cirrosa L.B.Smith) as the female parent and Guangxi Begonia (B.guangxiensis C.Y.Wu) as the male parent, the germplasm resources of the genus Begonia were collected and...

Abstract

Begonia 'Guiyun' is obtained by selecting and cultivating F1-generation population obtained by taking B. cirrosa as a female parent and B. guangxiensis as a male parent for artificial pollination hybridization. The Begonia 'Guiyun' is characterized in that asexual reproduction like leaf cutting is adopted to maintain specificity and excellent properties of Begonia 'Guiyun', dichasium is four rounds, number of blooming flowers is large, peduncle is long, leaves are large, oval shape is wide, and curly long pubescence is sparse; Begonia 'Guiyun' has excellent properties like pink tepals, flower diameter of 4-5cm, flowering from December to March of the next year and high cultivation adaptability like resistance to low temperature like -4 DEG C; a matched nutritional matrix of humus soil: perlite: fiber like sphagna: PK fertilizer according to a ratio of 40:3:3:0.5 is used for cultivation, and Begonia 'Guiyun' grows robustly under cultivation conditions that average room temperature is 20 DEG C, average air relative humidity is 50% and illumination intensity is 15000-20000Lx. Oblique illumination is properly increased in the flowering period, and phosphorus-potassium fertilizer is additionally applied, so that Begonia 'Guiyun' is large in flower number and big in flower size and bright in flower color.

Description

Technical field: [0001] The invention belongs to the field of biotechnology, and in particular relates to a method for cultivating a new variety of Begonia, and a new variety 'Guiyun' begonia (B.'Guiyun') cultivated by the method; Cloud' cultivation method. Background technique: [0002] There are more than 1,600 species of Begonia L. plants in the world, which are widely distributed in tropical and subtropical regions, and are also distributed in temperate regions. China is one of the countries with rich natural distribution of Begonia plant species. There are 224 known and published species, of which 197 species are unique to China, accounting for about 87.9% of the species distributed in China. Yunnan is located in the southwestern border of China, and is extremely rich in plant species, especially Begonias. There are 110 known and published species, accounting for about 49.1% of the natural distribution species in China, of which 74 species are unique to Yunnan. [000...
