Problems solved by technology

The "Yeyi" variety of Chunlan is mainly selected from wild species. So far, there has been no report of artificially breeding the "Yeyi" variety of Chunlan
[0004] Radiation mutation breeding is a common method for breeding new horticultural varieties. 60 Co-γ-ray radiation mutation breeding of Chinese orchid mutants has made some progress in China, but the breeding of new types of leaf art through radiation mutagenesis of Chunlan border art varieties has not been found in previous research literature. report

Embodiment Construction

[0028] The present invention will be further described in conjunction with the accompanying drawings and embodiments, but the content of the present invention is not limited thereto.

[0029] A way to create a new type of Bianyi Chunlan "Snow Mountain" leaf art:

[0030] (1) From February to March in the Jiangsu area, the temperature is around 0°C to 10°C. Choose the green plant material of Bianyi Chunlan "Snow Mountain" that grows vigorously and has a leaf bud size of 3mm.

[0031] (2) Bianyi Chunlan "Snow Mountain" materials were cultivated in a temperature-controlled solar greenhouse with an average temperature of 20°C for one week.

[0032] (3) Mix 72% of the bacterial fungicide agricultural streptomycin and 75% of the fungal fungicide chlorothalonil at a mass ratio of 1:1, and then make a 700-fold dilution with water to form a fungicidal fungicide The mixture of antiseptic and bacterial fungicide is set aside.

[0033] Take the Bianyi Chunlan "Snow Mountain" material ou...

Abstract

The invention discloses a method for obtaining a new type of leaf art through radiation mutagenesis of Bianyi Chunlan, which belongs to the technical field of flower breeding. Select the green plants of Chunlan side art variety in the leaf bud germination stage, after pre-irradiation treatment, use 60 Co-γ undergoes radiation mutagenesis, 60 The Co-γ-ray dose rate is 0.1-2Gy / min, and the irradiation dose is 5 Gy-10 Gy. After irradiation, the leaf buds are treated with 6-BA, and they are cultivated normally after 3 weeks. Technical breeding of new types of leaf art. The invention has strong operability, changes the current situation that Chunlan high-grade leaf art varieties are scarce and mainly relies on screening from wild species, and has high application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of radiation flower breeding. Background technique [0002] The trait of "Ye Yi" can greatly improve the ornamental value of orchids, and "Ye Yi Lan" is very popular in the Southeast Asian market. The "leaf art" of Chinese orchids (Chunlan, Cymbidium, Jianlan, Molan, Hanlan, etc.) is mostly golden, yellow, yellow-green, milky white and white, and can be divided into transparent, translucent and opaque. Various shapes and locations. Among the orchids in China, the most "leaf art" varieties are Taiwan's vertical leaf ink orchids. Only the bud varieties of "Dharma", there are now 20~ 30 types of leaf art. [0003] The types of leaf art of Japanese Chunlan are also very rich. At present, the Yeyi Chunlan in the market is mainly Japanese Chunlan. The selection and breeding of traditional Chinese Chunlan varieties pay attention to the petal shape, and the "leaf art" varieties are very rare, and the "leaf art" t...
