Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a new method for selecting excellent Chinese fir clones according to five trait indicators during the cutting period. This method does not require numerous "mathematical statistics" and esoteric "genetics" and "quantitative genetics". Equivalent genetic basic theory; no need for "large group" experiments; solves the problem of biological "genetic drift" and the defect of "sampling error"

Embodiment Construction

[0025] The present invention will be further clarified through the detailed description of specific embodiments below, but it is not intended to limit the present invention, but only for illustration.

[0026] 1 Test materials and their sources

[0027] The test began in 1984, and there were 222 Chinese fir clones (ie original materials). The original materials are: super seedlings of mixed line seedlings in annual seed orchard (selection intensity i=2 or more), annual mixed line super seedlings in productive nursery (selection intensity i=3 or more) and excellent tree "cutting" in Chinese fir young forest on the bud bar.

[0028] Sources of original materials: 19 in Fujian Province, 9 in Huitong County in Hunan Province, and 194 in Hengyang and Yongzhou in Hunan Province.

[0029] 2 Chinese fir clone seedlings

[0030] Each original plant is treated to its bent bar when it grows to 80-120cm centimeter through planting, promotes its axillary bud to germinate from rhizome pl...

Abstract

The invention discloses a novel method for selecting cedarwood superior clone according to the property index during the felling period. Five indexes including the age, the genetic character, the growth expression property, the wood physical mechanical property and the selection rate are used for selecting the cedarwood superior clone. The method provided by the invention is simple; the operation is convenient; the complicated mathematical statistics and the profound genetic basic theories of genetics, quantitative genetics and the like are not needed; the large-group test is not needed; the problem of genetic drift in the clone breeding is solved; the defect of sampling errors is overcome.

Description

technical field [0001] The invention relates to a method for selecting an excellent Chinese fir clone, which belongs to the field of forestry and the category of tree genetics and breeding. Background technique [0002] Clones can maintain the genetic characteristics of the female parent and have the greatest genetic benefit. The research on the selection of excellent Chinese fir clones began in the 1980s. In the 1980s and 1990s, due to ignorance of the internationally recognized statistical and genetic theories, some people in my country once put forward the so-called "fir fine clone breeding can be selected early" point of view, and formulated through several A few or dozens of clones are selected for production in annual trials. Among them are: 4-6 years "select the best" theory; 6-10 years "select the best" theory; 10-12 years "select the best" theory. Kaihua Forest Farm in Zhejiang Province is based on the theory of "selecting the best" for 4-6 years, and "selecting t...
