Problems solved by technology

However, according to the traditional breeding method, the clonal tea tree has the problems of small number of flowering, low hybrid seed-setting rate and low breeding efficiency. Therefore, how to overcome the difficulties, optimize the existing breeding technology and improve the double-clonal hybrid seed-setting rate is of great importance to the innovation of my country's tea tree species. It is of great significance to cultivate quality resources and cultivate excellent new varieties of tea trees

Embodiment 1

[0026] The method for improving the seed-setting rate of double-clonal tea tree hybridization in this embodiment uses the Guangxi clone tea tree improved "Guixiang No. 22" as the female parent, and the national-level clone tea tree improved "Yaoshan Xiulu" as the male parent to carry out artificial hybridization , including the following steps:

[0027] (1) "Printing" pruning: In May when the spring tea ends, the parent gardens of "Guixiang No. 22" and "Yaoshan Xiulv" are pruned for the first time. Cut off the branches and leaves, and then choose a row randomly, cut off the branches and leaves of the 2 Cong tea tree at one end 60cm from the ground to form a bunch of dwarf fir trees, and then cut off the branches and leaves at the second layer of leaves on the canopy of the adjacent 2 Cong tea trees to form A bunch of tall fir trees, and so on, dwarf fir trees and tall tree fir trees are arranged alternately, and the tea trees in adjacent rows are treated in the opposite way, t...

Embodiment 2

[0034] In the method for improving the seed-setting rate of double-clonal tea tree hybridization in this embodiment, artificial hybridization is carried out by using the national-level clone tea tree improved "Guixiang No. 18" as the female parent and the national-level clone tea tree improved "Fuyun No. 6" as the male parent. , including the following steps:

[0035] A method for improving the seed-setting rate of double-clonal tea tree hybridization, comprising the steps of:

[0036](1) "Printing" pruning: the first pruning will be carried out on the parent gardens of "Guixiang No. 18" and "Fuyun No. 6" in May when the spring tea ends. Cut off the branches and leaves, and then choose a row randomly, cut off the branches and leaves of the Lucong tea tree at one end 70cm from the ground to form a bunch of dwarf trees, and then cut off the branches and leaves at the 3rd leaf layer of the adjacent Lucong tea tree in the same row to form A bunch of tall fir trees, and so on, dwa...

Embodiment 3

[0043] The method for improving the artificial hybridization of double-clonal tea trees in this embodiment uses the national-level tea tree improved variety "Yaoshan Xiulu" as the female parent, and the national-level cloned tea tree improved variety "Huang Guanyin" as the male parent for artificial hybridization, including Follow the steps below:

[0044] A method for improving the seed-setting rate of double-clonal tea tree hybridization, comprising the steps of:

[0045] (1) Pruning of "Pinzi type": The first pruning will be carried out on the parent gardens of "Yaoshan Xiulu" and "Huangguanyin" in May when the spring tea ends. Cut off, then randomly select a row, cut off the branches and leaves of the 4-cong tea tree at one end 65cm from the ground to form a bunch of dwarf trees, and then cut off the branches and leaves at the 2-layer leaf layer of the adjacent 4-cong tea tree to form a Bundle of tall fir trees, and so on, dwarf fir trees and tall tree fir trees are arran...

Abstract

The invention discloses a method of increasing cross setting rate of double clone tea trees and belongs to the technical field of tea tree crossbreeding. The method includes following steps: (1), triangularly trimming; (2), excavating two furrows, and applying phosphorus potassium fertilizer in one furrow; (3), setting up a pest preventing net; (4), collecting and storing male parent pollen; (5), artificially pollinating; (6), thinning branches and leaves. The method which is simple and easy to implement is adopted for artificial cross pollinating on a certain scale to obtain more crossed offsprings, so that the tea tree crossbreeding process is accelerated; the method of triangular trimming, excavating two furrows while applying the phosphorus potassium fertilizer in one furrow and setting up the pest preventing net is adopted, so that air ventilation and light transmission of a clone tea garden can be fully improved, cost can be effectively saved, fertilizer utilization efficiency can be improved, flowering amount and setting rate of the clone tea trees are increased greatly, and the problem of low breeding efficiency and artificial cross setting rate in the prior art is solved effectively. The method is simple and easy to operate and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to a method for improving the hybrid seed setting rate of double clone tea trees, and belongs to the technical field of tea tree hybrid breeding. 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, and has achieved remarkable results. Among the 97 national-level fine varieties that have been approved, 30% are selected through hybrid breeding. For example, 15 varieties such as Fuyun No. 6, Zhenong 113, and Huangqi were bred from natural hybrids of Fuding Dabai tea and Yunnan big-leaf species. 14 varieties including national-level fine varieties Shuyong No. 1, Qianmei 809, and Mingke No. 1 were selected from the offspring of the cross-breeding combination of species and other species. The above varieties are all selected fr...
