Purpose&Contents
The improvement of soil environment in highlands by developing customized soybean varieities, establishing cultivation methods, and creating new income sources

Results
□ (Soil health) Introduction of soybean in highland for ‘essential environment’ beyond eco-friendly
❍ Selecting 10 cultivars with excellent cultivation stability functionality in highlands based on big-data
- The establishment of database related to agricultural phenotype of 154 cultivars evaluated in 3 locations for 3 years
* DB: flower color, hilum color, flowering time, maturity time, quantity
- The selection of customized cultivars for improving highland environment
* In highlands, ‘Daepung’ was higher lodging resistance and 2.8 times higher isoflavone content than ‘Daewon’.
☞ Presenting soybean cultivars that meet the needs of cultivars and consumers based on big-data
❍ Proper cultivation method of ‘Daepung’ adaptable to highlands
- Sowing 3 seedlings per hole induced 10 % increase in yield and decrease in stem thickness, which make harvesting soybean easier
- Presenting a crop cultivation model to plant soybeans twice in 5 years in highlands
☞ On-site technical support for soybean farmers in highlands
❍ The effects of soil recovery by introducing soybeans to highlands
- Enhancing useful soil microbial activity
- Reducing soil pathogen activity
* Growing soybeans in fileds with a slope of more than 7% reduces soil loss by more than 70% than planting cabbage, reduces fertilization by 30%, and increase cabbage productivity by 10-30%
☞ Income preservation support for converting cabbage into soybeans in highlands (Policy proposal)

□ Transforming breeding methods into new breeding methods based on big data of genome
❍ DB construction for new breeding platform based on genotype and phenotype
* The establishment of database related to agricultural phenotype of 154 cultivars and 603 lines evaluated in 3 locations for 3 years
☞ Receiving research award from the Korean Society of Breeding Science(No. 32): Chromosome reshuffling patterns of Korean soybean cultivars using genome-wide 202 indel markers
❍ Replacing molecular markers of MyCrops_Soybean with phenotype-linked molecular markers to enhance the function of molecular development platform
* The search for 50 variation blocks and SNPs related to flowering and maturity of soybean
☞ The development of PCR-based simple and accurate identification method using E1 gene-related indel
❍ The development of the intermediate breeding materials in which the superior traits were accumulated improved the breeding efficiency of new varieities.
☞ We presented the new model that helps breeders and farmers make decisions.

□ The development of fermentation technology to improve human absorption of isoflavones
❍ When soybeans were grown in highlands, the isoflavone content was 21-99% higher than that of lowlands
❍ The development of Cheonggukjang with improved human absorption of isoflavone using the fermentation process after soaking and drying pretreatment
* Compared with conventional fermentation, the developed technology had a 1.6-fold increase in the conversion of isoflavones from glycones to aglycones
❍ Ingesting the fermented soybeans alleviated prostatic hypertrophy and osteoporosis
☞ Creating new added value using varieties with high adaptability to highlands

Expected Contribution
❍ It is expected that the introduction of highland soybeans will promote sustainable management and efficient use of the soil
❍ It is applicable to the development of a method to accurately predict adaptability to highlands using DNA information
❍ Leading the development of the food market to meet new social needs
