Embodiment 1

[0034] Step 1 In the field of soybean species identification, select 5 technical experts who have been engaged in soybean species identification for 10 years and above, and have technical titles of deputy senior or above, to form a wild soybean evaluation expert group;

[0035] The second step is the source of standard samples: wild soybean seeds collected in the field are identified by experts, and then planted in isolation during the growing season, and further verified according to the characteristics of the whole plant and flowers and fruits to confirm the authenticity of wild soybeans.

[0036]The third step standard sample multiplication: soil disinfection treatment ►put into flower pots ►put into isolation net room ►plant wild soybean seeds ►observe and record ►harvest, dry in the sun ►preserve; according to local climate conditions, choose different sowing period. Firstly, disinfect the soil, which can kill other weed seeds and pathogenic bacteria in the soil, then put...

Abstract

The invention belongs to the plant quarantine standard sample technology research and development field, and in particular, relates to a preparation method for a soybean standard sample. The preparation method for the wild soybean standard sample mainly includes determination of an expert group, standard sample source, standard sample expanding propagation, standard sample screening, standard sample production process, standard sample uniformity inspection, standard sample stability inspection and standard sample storage; wild soybean seeds collected in fields are used as raw material, wild soybean standard samples having representativeness are prepared through isolation planting, expanding propagation, screening, preparation, uniformity inspection, stability inspection, packaging and storage and other procedures, an identification basis is provided for plant inspection and quarantine works, and a real object reference is provided for protection of national species resources.

Description

technical field [0001] The invention belongs to the technical research and development field of plant quarantine standard samples, in particular to a method for preparing soybean standard samples. Background technique [0002] wild soybeans ( Glycine soja ), the original ancestor species of cultivated soybean. Wild soybeans grown under natural conditions have never been affected by artificial selection in genetics, so many rich functional genes have not been lost due to artificial selection. These genes are likely to be key genes that are urgently needed for the survival of soybeans. The high-protein, multi-resistance, wide-adaptability, and high-quality materials in wild soybean resources can be directly used for high-quality, disease-resistant, and high-yield breeding research in cultivated soybeans. Wild soybeans are also the most important carrier for soybean phylogeny and evolution research. One is the important genetic basis for the sustainable development of soybean...
