Through scientists’ hard working,‘Hybsoy 1’,the first variety of hybrid soybean,was examined and approved by Jilin Provincial Variety Examination and Approval Committee in 2002,and ‘HybSoy 2’ was examined and approved in 2006.From 2000,using of the leaf cutting bee,honeybee and thrips for pollination of soybean,and reproducing of male-sterile line and breeding technology of hybrid soybean was researched not only in net room but also in open fields.The hybrid soybean combination and small amount seed was produced in net room pollinated by honey bee or leaf cutting bee,and the fertility of male-sterile line was about 55.9%-100%.The yield of male-sterile line was about 50-80% in open fields,pollinated by honey bee or leaf cutting bee in dry and irrigating fields.The yield of hybrid seed was quite ideal.Breeding bases has been set up in the dry regions of the western Jilin province and the eastern Inner Mongolia by Academy of Agricultural Sciences of Jilin Province.Hybrid soybean was produced at a large scale and experiments were carried out for several years.The seed producing technology was basically ready until now.
