Last Updated: 2024/11/06, The sexual offspring of tea plant are produced by the combination of male and female cells, and a breeding method of new varieties is developed through selection. A variety bred is called a sexual variety. The method is: 1. Selection of superior individual plant or type: single plant selection or group selection from the original material nursery or production tea garden according to breeding objectives; 2. Seed collection and seedling raising: for the primary selected individual plant or group, the seeds were collected respectively, and the seedlings were raised according to the system, and the seedling characters and variety purity were identified. Family or group comparison trial: compare selected families or groups with controls

The sexual offspring of tea plant are produced by the combination of male and female cells, and a breeding method of new varieties is developed through selection. A variety bred is called a sexual variety. The method is:

1. Selection of superior individual plant or type: individual plant selection or group selection from the original material nursery or production tea garden according to breeding objectives

two。 Collecting seeds and raising seedlings: for the primary selected individual plant or group, the seeds were collected respectively, and the seedlings were raised according to the system, and the seedling characters and variety purity were identified.

3. Family or group comparative test: the selected families or groups were compared with the control varieties, and the high yield, adaptability and stress resistance were systematically identified.

4. Regional trial: seeds of selected excellent individual plants or asexual offspring of groups were sown in areas with different ecological conditions for regional adaptability test.

5. Seed production test: mainly identify the seed production capacity and maternal genetic ability of the asexual offspring of selected individual plants and groups.

6. Breeding and promotion: the last selected individual or group, the establishment of seed collection garden, through sexual reproduction, the promotion of improved varieties.
