美国大豆资源利用与高油大豆合丰57的创新

The Utilization of American Soybean Resources and the Innovation of High-Oil Soybean Variety Hefeng 57

利用美国高油大豆种质资源Hobbit与本单位自主创新的高油大豆品种合丰42号杂交,对其后代材料F2进行辐射诱变处理,经过多年连续定向选择和利用先进的品质分析与病害鉴定技术,创新出既高油又高产、抗病的大豆新品种合丰57。该品种油分含量22.87%,黑龙江省区域试验平均产量2431.4kg/hm2,较对照品种合丰47号平均增产13.8%;生产试验平均产量2119.7kg/hm2,较对照品种合丰50号平均增产11.6%。

A new soybean variety Hefeng 57 was developed on the basis of the cross of American high-oil soybean resources Hobbit and local high-oil soybean variety Hefeng 42 and neutron irradiation of the cross progenies F2,through years of successive targeted selection integrating with the modern methods of quality analysis and resistance identification.It was characterized by high oil content with average 22.87%,high yield performance and resistance to frogeye leaf spot,the average yield was 2431.4kg/hm2 in the regional test of Heilongjiang province,13.8% higher than the control variety Hefeng 47,and the average yield was 2119.7kg/hm2 in the production test,11.6% higher than the control variety Hefeng 50.
