Method for selecting improved variety Jinlin No.1 of fir timber forest

Abstract

The present invention discloses a method for selecting an improved variety of a fir timber forest from mixed line common seedlings of local fir provenances. The method comprises the steps of selectingannual fir seedlings as parents in proportion in a fir production nursery in which local mixed line seeds are used for sowing, cultivating original plants of the parents into clones in a cloning manner, selecting relatively good clones as excellent clones from the clones, selecting one especially excellent clone as the improved variety of the fir clone timber forest from the excellent clones, andnaming the improved variety as Jinlin No.1. According to the method, a mode of selecting the improved variety of fir is innovated, and a new way for selecting the improved variety of the fir is created; a new variety of the fir can be selected out in a production period, so that the time of selecting the improved variety is shortened; and the selection method is scientific and simple, a selectionresult is accurate and reliable, and the defect of uncertainty of the offspring yield-increasing effect due to genetic shift is overcome.

Description

Technical field [0001] The invention relates to a method for selecting fine species of Chinese fir timber forest from local provenance "mixed common seedlings" by means of "vegetative propagation", which belongs to the forestry field and the category of forest tree genetic breeding. Background technique [0002] In the 1950s, my country had already carried out the selection of fine varieties of fir. Initially, it was selected in a large area in the mother forest, and then in the mother tree and progeny forest. [0003] Selection methods of improved Chinese fir varieties in the late 1970s: (1) Mixed-line collection of seeds from the parent forest; (2) Selection of "a small amount of superior trees" from the parent forest as the seed collection; (3) Progeny of the superior trees from the parent forest Select the mother tree for seed collection. [0004] Seed collection in the above manner has the following shortcomings: 1) The selection of seed-harvesting mother trees has a long perio...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a method of "vegetative propagation" to select and breed Chinese fir forest species, which solves the defect of uncertainty in the effect of increasing production of offspring in "sexual breeding"; and can accurately identify a certain clonal The growth performance of improved varieties in different production stages; new varieties can be selected within one production cycle, shortening the selection time of improved varieties,
