Embodiment

[0013] A kind of dendrobium orchid new variety breeding method, comprises the steps:

[0014] Step 1, select the lateral buds and terminal buds of Dendrobium nobile orchid with excellent flower shape and color as explants, and cultivate them in the mutagenesis medium for 40 days to form protocorms; the formula of the mutagenesis medium is: 5 g of sucrose, peptone 10g, 2.5g of agar powder, 1.5g of ethyl methanesulfonate, 0.2g of clomazone, and make up to 1L of water; the culture temperature is 20-25°C, the light intensity is 1500-1800lx, and the light time is 12h / day;

[0015] Step 2, the protocorm-like continues to develop, and some protocorm-like plants develop into plantlets, and the protocorm-like plants that form the plantlets are transferred to the proliferation medium for value-added differentiation and culture for about 30 days to form seedlings; the formula of the proliferation medium is: Huabao No. 1 1g, Huabao No. 2 1g, peptone 5g, coconut juice 2g, sucrose 20g, agar...

Abstract

The invention relates to a breeding method for a new variety of Dendrobium orchid, which comprises the steps of mutagenesis culture, multiplication culture, rooting and strong seedling cultivation, and seedling training to obtain the new Dendrobium orchid seedlings. In the present invention, the lateral buds and terminal buds of lines with excellent flower shape and flower color are used as explants, and the mutagenesis medium is used to induce mutagenesis, from which an excellent individual plant with variation is selected, and a new variety is formed through propagation, and cultivated. The cycle is short and the survival rate is high.

Description

technical field [0001] The invention relates to a method for breeding new varieties of tropical orchids, in particular to a method for breeding new varieties of dendrobium orchids. Background technique [0002] Dendrobium is a tropical orchid with high ornamental and medicinal value. Due to the high economic value of Dendrobium orchids, wild resources have been over-harvested. The popular dendrobium varieties on the market are mostly hybrid varieties. The hybrid breeding cycle of the existing Dendrobium orchid is relatively long, and it usually takes 7-8 years for a new hybrid variety to be cultivated. Contents of the invention [0003] The object of the present invention is to provide a kind of breeding method of new dendrobium orchid, solves the problem that the cultivation cycle of existing technology is longer. [0004] A kind of dendrobium orchid new variety breeding method, comprises the steps: [0005] Step 1, select the lateral buds and terminal buds of lines w...
