Description
Technical Field
The invention belongs to the technical field of forest breeding, and particularly relates to a method for rebuilding a forest seedling seed garden into a seedling and clone mixed seed garden.
Background
Forest seed gardens are the bassinets for most artificial forests. In order to obtain a reliable and reproducible seed supply, forest seed plantations are often required or preferred, but genetic gains often become very important as forest breeding is already in an early stage. To date, forest seed plantations are the most important interface between forestry and tree breeding and support research. Through the forest seed garden, resources required by offspring are created, and in addition, the forest seed garden is also a tool for resisting global warming and realizing sustainable development; a better forest seed orchard means a better future world. In addition, the forest seed garden also plays an important role in protecting the gene resources of trees.
In northern Europe countries (Sweden, Finland, Denmark and Norway, etc.) in the 30-40 th century, forest seed gardens of Pinus densiflora, Norway spruce, Larix gmelini, etc. were built. In the 50 s, forest seed gardens were established successively in the united states, canada, australia, new zealand, japan, and so on. At present, some countries have established 3 rd generation seed gardens in turn and implement 3 rd round of forest improvement work. Loblolly pine breeding in the united states has now entered passage 4.
The construction of the forest seed orchard in China starts from the 60 th of the 20 th century, the last 70 th and the early 80 th of the century, the forest seed orchard is successively established for main afforestation tree species in China, at present, most of the tree species finish the improvement work of the 1 st generation, the improvement is developing to the high generation, and the construction of the seed orchard of the 2 nd generation and the 4 th generation of China fir are started.
Forest seed gardens are classified into 2 categories according to different material properties: clonal seed gardens and seedling seed gardens. The 2 kinds of forest seed gardens have advantages and disadvantages respectively.
For the clonal seed orchard, the advantages are mainly shown as follows: the excellent genetic characteristics of the parents are maintained, the blossoming and the fructification are advanced, the improved seeds are provided quickly, the grafted plants are dwarfed, the management and the seed collection are convenient, and the character effect of high heritability is good; the disadvantages are: the method has the advantages of difficult vegetative propagation, high technical difficulty of the tree species, higher garden building cost, low heritability effect and the like.
For the seedling seed garden, the advantages are mainly as follows: the garden building cost is low, the trait effects of obvious little guo selection in the early stage and low heritability are good, the technical problem of asexual propagation does not exist, and the method can be combined with the measurement of offspring; the disadvantages are: limited by early selection effect, late seed setting, low initial seed yield, high risk of inbreeding and the like.
For a tree species of a forest, either a clonal or a seedling seed orchard will generally be selected based on the characteristics of the tree species being built and the materials from which the orchard will be built. In practice, the following may often occur:
1. because the asexual propagation technology of the tree species is not solved temporarily, a clonal seed garden is selected originally, and a seedling seed garden is forced to be selected;
2. in the construction of seedling seed gardens, due to design defects or human errors, such as adjacent arrangement of parent numbers, serious close-relative propagation exists.
How to scientifically and rapidly modify the seed gardens under the 2 conditions is an important scientific problem for scientists. According to the inquiry of literature and patent information, no report is found about the reconstruction of a forest seedling seed garden into a mixed seed garden of seedlings and clones.
Disclosure of Invention
In view of the above, the present invention aims to provide a method for reconstructing a forest seedling seed orchard into a mixed seedling and clone seed orchard, which has the characteristics of science, simplicity, convenience and rapidness.
The invention provides a method for reconstructing a forest seedling seed garden into a seedling and clone mixed seed garden, which comprises the following steps:
1) surveying and analyzing the growth and seed setting data of the original seed orchard;
2) preparing a remaining and bad scheme and an anvil fixing diagram according to the analysis result in the step 1);
3) redesigning the seed garden by adopting seed garden design software;
4) replacing the inferior individuals with clone grafted seedlings.
Preferably, the survey time of the growing and maturing data of the original seed orchard in the step 1) is 3 to 7 years in the plant growing period.
Preferably, the program for remaining good and bad in the step 2) is to remove all individuals with growth traits (tree height and breast diameter) lower than 15-100% of the average value of the plants in the seed orchard and with the fruiting quantity lower than 5-100% of the average value of the plants in the seed orchard.
Preferably, the anvil map in the step 2) is 2 anvil maps which are redrawn after the optimization and the deterioration are left. Preferably, the software for designing the seed orchard in step 3) is SPQG (ver.1.2 aspiration macros), which includes a seed orchard design module, and can automatically identify the original plants retained in the 2-time anvil plot, and can design a seed orchard configuration plot with maximized genetic relationship (i.e. the lowest inbreeding degree) between the plants.
Preferably, the plant number of the clone grafted seedling in the step 4) is the plant number on a seed garden configuration diagram designed by SPQG software.
The method provided by the invention is scientific and ingenious in design, has the advantages of both the seedling and clone seed gardens, can realize the algebraic upgrading of the seed gardens by one-time reconstruction, is suitable for reconstructing various forest seedling seed gardens, and has wide application value in the upgrading and reconstruction of the forest seed gardens.

Detailed Description
The method for reconstructing a forest tree seed orchard into a mixed seedling and clone seed orchard provided by the invention is described in detail below with reference to the examples, but the method is not to be construed as limiting the scope of the invention.
Example 1
The silver wood seed garden in the national fine variety base of the west mountain forest farm in the big foot area of Chongqing city is a seedling seed garden, the same parents are adjacent due to the design defect, and in order to avoid huge loss caused by reconstruction, the method is adopted for scientific transformation, so that perfect gorgeous transformation is realized.
Firstly, the growth and seed setting properties of each tree are investigated on the existing silver wood seed gardens. Since the trees in this example have not reached the flowering and fruiting age, the trees are made superior and inferior according to the growth traits.
Taking the first cell of the fifth big area of the existing silver wood seed garden as an example, the original planting pattern is as follows:
obviously, the parents (clone/family) originally planned in the cell are arranged in sequence and fixedly matched, and do not meet the basic design criteria of the seed garden (random matching and farthest genetic relationship between adjacent parents). According to the SPGG software, the position information planned by the cell permanent planting graph is as follows:
1111111111111000000
