Dendrobe breeding method

Abstract

The invention provides a dendrobe breeding method, and relates to a plant variety breeding method. The dendrobe breeding method comprises the following steps: collecting Dendrobium officinale seeds, selfing parent plants gained through dendrobe seed breeding to gain capsule, cultivating the capsule to gain germchit, screening better germchit, and hardening-seedling and transplanting after asexual reproduction of the germchit. Through the hybridization to the Dendrobium officinale parent plants, the method of combining a sexual reproduction manner and an asexual reproduction manner is adopted to breed a dendrobe clone variety; the dendrobe clone variety is suitable for being planted in a plurality of places in Yunnan such as Wenshan, Banna, Puer, Baoshan, Dehong and the like; an important value is brought to improve the mess dendrobe planting varieties in Yunnan province, enrich dendrobe seed resource and push seed selection adapting to local condition by peasant households.

Description

technical field [0001] The invention relates to a plant variety breeding method, in particular to a dendrobium breeding method. Background technique [0002] Dendrobium officinale Dendrobium officinale Kimura et Migo is a perennial epiphytic herb of Orchidaceae. In the traditional medicine of the motherland, "Compendium of Materia Medica" said that Dendrobium candidum has "strengthening yin, benefiting essence and thickening the stomach, nourishing the internal deficiency, growing muscles, improving intelligence and eliminating shock, lightening body and prolonging life. "; as a rare medicinal material, it is listed as the first of the nine Chinese celestial grasses in "Tao Zang". According to modern pharmacological experiments, the active ingredients of medicinal Dendrobium are mainly Dendrobium polysaccharides, which have significant curative effects on various diseases; at present, there are dozens of Chinese patent medicine products that use Dendrobium as raw materials...

AI Technical Summary

Problems solved by technology

[0006] Some Dendrobium species are artificially bred, and are also used in the innovation of Dendrobium seeds through hybridization, such as artificial pollination when Dendrobium candidum blooms, and then select multiple parents to prepare hybrid combinations, and then use the hybrid fruits as explants to multiply to obtain seedlings ; Although the use of asexual reproduction of stem tips, stem segments and other organs to produce clustered buds to obtain regenerated plants has been reported, such as the successful reports of various Dendrobium species such as iron skin and golden hairpin in China, foreign Arditti et al. and Mosich et al. Segments are used as explants to successfully reproduce Dendrobium vegetatively, but there is no public report on the combination of the two to cultivate Dendrobium clonal varieties
