A kind of seed production method of double clone hybrid seed of tea tree

Abstract

The invention relates to a seed production method of tea tree biclonal hybrid seeds. Specifically, it is the first to discuss tea tree in seven aspects such as parent selection, combination selection, seed production site isolation, planting specifications, harvesting and retention methods, fertilization methods, and pollination techniques. The seed production method of double clone hybrid seed (hereinafter referred to as double clone). The method of the invention pertinently solves the problem of difficult production of tea tree double-clonal hybrid seeds. It improves the survival rate and seed setting rate of the double-clonal hybrid seeds of tea trees, and lays the foundation for the breeding and promotion of the double-clonal F1 sexual line, thereby realizing large-scale planting and turning resource advantages into industrial advantages.

Description

technical field [0001] The invention relates to a method for producing hybrid F1 hybrid hybrids of double clones of tea trees (hereinafter referred to as the method for producing double clones of tea trees), and belongs to the technical field of new tea variety selection and breeding. Background technique [0002] Since entering the 21st century, my country's tea industry has shown a thriving scene. The improvement of tea tree clones is advancing at an unprecedented speed. However, the "one size fits all" breeding method is also a problem that cannot be ignored. For example, in cold alpine areas and high mountain tea areas, or in some mountainous areas with less rainfall, prone to drought, and difficult to implement irrigation, if forced to promote clonal improved varieties, the result is often counterproductive, and the gains outweigh the losses. This is because the root system of the clonal tea seedlings belongs to the fibrous root system, which is shallowly distributed ...
