Embodiment 1

[0033] Embodiment 1: (OT type hybrid line lily virus-free tissue culture rapid propagation method 1)

[0034] The specific method is as follows:

[0035] (1) Preparation and standby of the culture medium: the components including the basic medium and the culture medium at each stage of tissue culture and the weight of each component in each liter of culture medium are formulated as follows.

[0036] (2) Selection and sterilization of explants: In early March, the dormant and broken bulbs were taken, treated with heat and humidity at 50°C for 70 minutes, soaked in 75% alcohol for 0.5 minutes, rinsed with sterile water for 3 to 5 times, and then Sterilize with 0.1% mercuric chloride solution for 15 minutes, rinse with sterile water for 3 to 5 times, sterilize with 10% sodium hypochlorite aqueous solution for 15 minutes, and finally rinse with sterile water for 3 to 5 times, as explants for detoxification tissue culture .

[0037] (3) Induction culture: Take a 0.2-0.3mm shoot t...

Abstract

The invention discloses a quick breeding method of OT type hybrid system lily pull-off toxic group planting in plant group planting quick breeding technical domain, which comprises the following steps: allocating medium; choosing stem tip of lily seed source bulb as explant; evoking; breeding; expand-culturing bulb; freezing; replanting; testing virus; getting the product. This invention possesses high breeding coefficient, low cost and strong practicability, which can be spread used.

Description

technical field [0001] The invention relates to the technical field of plant tissue culture and rapid propagation, in particular to a method for virus-free tissue culture and rapid propagation of OT hybrid lilies. Background technique [0002] OT-type hybrid lily (Oriental×Trumpet Hybrid) is a hybrid series of Oriental Lily and Trumpet Lily / Aurelianos hybrid line. It is a perennial ornamental plant of Liliaceae, mainly used for cut flower cultivation. Its plant stem strength, disease resistance, heat resistance, salt and alkali resistance and other traits are obviously better than oriental lily, so it has a good market development prospect. In recent years, the production of cut lily flowers in my country has increased by more than 20% annually, but lily bulbs have always been dependent on imports from abroad. However, viral disease infection has caused serious degradation of lily species, which has brought huge economic losses to lily bulb producers...
