Begonia cultivating and planting method

Abstract

The invention discloses a cultivating and planting method of a begonia named Yinjiao. According to the invention, an artificial pollination method is adopted, begonia dryadis irmsch. is adopted as a female parent, B.'White King' is adopted as a male parent, and sexual hybridization is carried out; an offspring individual plant is subject to self-pollination, and the variety Yinjiao is obtained through selective breeding from an F2 generation colony; the chromosome numbers of the parents and the filial generation are determined; and the variety Yinjiao obtained through the previous cultivationsteps is planted in humic soil under a temperature of 15-25 DEG C and an air relative humidity of 65-75%, where in the humic soil is air-permeating and is rich in organic matters. Also, the drainage of the humic soil is good.

Description

Technical areas: [0001] The present invention belongs to the field of biotechnology. Specifically, it relates to a method for cultivating Begonia plants and a new variety 'Yinjiao' obtained by cultivating it by this method. It also relates to a method for cultivating the new Begonia variety 'Yinjiao'. Background technique: [0002] There are about 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 zones. China is one of the countries with relatively abundant natural distribution of Begonia species. There are currently 224 known and published species, of which 197 species are unique to China, accounting for approximately 87.9% of the species distributed in China. Yunnan is located in the southwestern border of China and has extremely rich plant species, especially Begonia. There are 110 known and published species, accounting for about 49.1% of the species naturally distribut...

Problems solved by technology

Breeding of begonias in my country started relatively late, and mainly carried out the breeding of new varieties of begonias mainly based on sexual hybridization, combining natural variation selection and sexual hybridization, focusing on leaf viewing, and combining leaf viewing and flower viewing. Combining fragrant flower varieties, few new varieties have been bred so far. The ornamental features such as leaf shape, markings, color, bristles, etc., and the adaptability to low temperature, low humidity, and slightly strong light are the breeding goals. From sexual hybridization F2 and F1 generation populations, and the report of breeding new varieties in aerospace breeding M1 generation populations
