Embodiment 1

[0019] Example 1: Using Longjing 43 as the female parent and Baihaozao as the male parent to carry out artificial hybridization using the "petal pollination method", the specific method is as follows:

[0020] 1) Longjing 43 female parent tea garden selection: choose a tea garden with a large distance between tea rows and better light transmission as the hybrid female parent garden;

[0021] 2) Pollen collection and drying: When Longjing 43 reaches the full flowering stage, collect budding flowers from the male parent Wu Niu in the morning; put a layer of absorbent paper in the carton, and then put the collected flowers evenly, and put them on the upper layer Cover with another layer of absorbent paper, place it indoors, and use it the next day;

[0022] 3) Pollen collection: Before pollination, take a piece of clean white paper, take the flowers that have been dried overnight, lightly brush the anthers with a soft brush to shake off the pollen, and collect the fallen pollen w...

Abstract

The invention relates to an artificial hybridization type petal pollination method for a tea tree, and belongs to the technical field of cross breeding methods. The artificial hybridization type petal pollination method is characterized by comprising following steps of (1) confirming an object to be pollinated; (2) collecting pollen; (3) drying the pollen and storing; (4) gathering the pollen; (5) castrating; (6) pollinating petals; (7) bagging; and (8) removing bags. When the efficient artificial hybridization is performed in a land for growing field crops, as the method is adopted, the pollination speed is high and the use ratio of the pollen is high, the pollen consumption amount is saved, and compared with conventional pollination methods, for the method disclosed by the invention, the use ratio of the pollen and the pollination speed are increased by more than two times, the method is simple to operate; through the petals are relatively soft, the stigma can not be damaged; the hybridization maturing rate is increased.

Description

technical field [0001] The invention belongs to the technical field of hybrid breeding methods, in particular to a tea tree artificial hybrid petal pollination method. Background technique [0002] Heterosis is a common phenomenon in the biological world, and the use of heterosis has become one of the main ways of tea tree breeding. my country's tea tree breeding method has changed from systematic selection to hybrid breeding, such as the Zhe Nong series of tea tree varieties bred by Zhejiang University, Yingshuang and Cuifeng bred by Hangzhou Tea Research Institute, and the Tea Research Institute of Fujian Academy of Agricultural Sciences. The Fuyun series bred are all selected from the natural hybrid offspring of Fuding Dabaicha and Yunnan Daye. Through artificial hybridization, Qianmei 419, 502, 601, and 701 were bred by the Tea Science Institute of Guizhou Province; Shuyong 307, 703 and other varieties were bred by the Tea Science Institute of Sichuan Province. Indian t...
