Abstract

The invention provides a wolfberry anther culture breeding differential medium and belongs to the technical field of tissue culture of wolfberry. The special medium is composed of major elements, minor elements, iron salt and complex agent, organic ingredients, inorganic additive, plant growth regulator, physiological activator, carbon source, coagulator and other additives. The wolfberry anther culture breeding differential medium is adopted to differentiate wolfberry anther callus, wolfberry anther callus green seedling differentiation rate is high, differentiation effect is good, and medium browning degree is low, so that wolfberry anther efficiency is improved greatly and breeding process is accelerated.

Example Embodiment

[0034] Example 1
[0035] Prepare the culture medium with the following formula:
[0036] Macroelements: KNO 3 950mg/L, NH 4 NO 3 825mg/L, KH 2 PO 4 675mg/L, MgSO 4 ∙7H 2 O 1500mg/L, Glutamine 390mg/L, CaCl 2 ∙2H 2 O 220mg/L;
[0037] Trace elements: MnSO 4 ∙4H 2 O 18mg/L, ZnSO 4 ∙7H 2 O 27.5mg/L, H 3 BO 3 6.25mg/L, KI 0.8mg/L;
[0038] Iron salt and complexing agent: FeSO4 ∙7H 2 O 42.5mg/L, Na 2 -EDTA∙2H 2 O 56mg/L;
[0039] Organic ingredients: inositol 50mg/L, vitamin B1 0.4mg/L, vitamin B6 0.5mg/L, niacin 5.0mg/L, adenine 22.5mg/L, proline 2.0mg/L, folic acid 0.4mg/L , Biotin 0.1mg/L;
[0040] Inorganic additives: activated carbon 9g/L, N-methyl-nitrosourea 27.5mg/L;
[0041] Plant growth regulator: 2,4-D 1.0mg/L, KT 1.7mg/L;
[0042] Physiologically active substances: Lycium barbarum root extract 12.5g/L;
[0043] Carbon source: sucrose 27.5g/L, fructose 13.5g/L;
[0044] Coagulant and other additives: plant gel 5.75g/L, sorbitol 22.5g/L, hydrolyzed protein 1.0g/L.
[0045] Lycium barbarum varieties Ningqi No. 3 and Lycium barbarum Huangguo were selected as anther donors for anther culture, and flower buds in the middle and late stage of uninucleate development were taken from the two varieties of Lycium barbarum plants that were robust and free of diseases and insect pests at the early flowering stage or full flowering stage. As a test material, callus of Lycium barbarum was induced. After the callus is formed (when the diameter reaches about 2 mm), the Lycium barbarum callus is inoculated into the differentiation medium. After the Lycium barbarum callus completely differentiates into Lycium barbarum seedlings, the differentiation rate of the Lycium barbarum callus green shoots and the albino seedling rate are counted.
[0046] Green seedling differentiation rate (%) = number of differentiated green seedlings/number of transferred callus × 100%; rate of albino seedlings (%) = number of albino seedlings/number of transferred callus × 100%.

[0051] Iron salt and complexing agent: FeSO 4 ∙7H 2 O 42.5mg/L, Na 2 -EDTA∙2H 2 O 56mg/L;
[0052] Organic ingredients: inositol 50mg/L, vitamin B1 0.4mg/L, vitamin B6 0.5mg/L, niacin 5.0mg/L, adenine 22.5mg/L, proline 2.0mg/L, folic acid 0.4mg/L , Biotin 0.1mg/L;
