Description
Technical field
The present invention relates to Tea planting technical field, specially a kind of screening technique of almond perfume (or spice) Tea Germplasm.
Background technique
" almond is fragrant " black tea is using black tea made of a kind of special tea tree Raw material processing, and made tea has almond milk
Perfume (or spice), this kind of germ plasm resource is extremely rare, and can not be recognized from the biology morphology of tea tree, therefore this kind of Tea Germplasm
It is extremely difficult to carry out breed breeding.
Current screening technique is to carry out black tea processing trial-production respectively after single plant acquires fresh leaf or single plant cutting propagation, still
Both methods workload is very big, and breakneck acceleration is relatively slow.Using the method for single plant acquisition fresh leaf processing trial-production, due to single plant tea
Dark brownish green negligible amounts are set, processing difficulties cannot keep the original characteristic of germ plasm resource, therefore cause the tea tree with certain characteristic
Germ plasm resource can not screen, and every plant of tea tree individually processes labor intensive and the time is extremely more, low efficiency, and utilize asexual cuttage
Nursery, it is breeding time needs 4 years or more, this large-scale to the method for carrying out processing trial-production after cuttage seeding cultivating and growing again
Cutting propagation may finally screen the kind that can process " almond is fragrant ", but this method from thousands of parts of Tea Germplasm
Have the shortcomings that time-consuming, at high cost, heavy workload.Therefore a kind of new technical solution is needed, apricot can be quickly filtered out
Benevolence perfume (or spice) tea tree breed, convenient for quickly planting this Rare Kinds.
