合丰号高油及矮秆或半矮秆大豆的品种选育

Breeding Soybean Varieties of Hefeng with High Oil Content and Dwarf or Semi-dwarf

利用美国高油、矮秆和耐密植大豆种质资源与高产广适应性大豆杂交,通过单交及简单回交与辐射诱变育种相结合,经过连续定向选择,利用先进的品质分析、抗病鉴定等方法进行品种选育研究。结果表明：选育出高油、高产和抗病的4个大豆新品种合丰42、合丰52、合丰57、合农60,脂肪含量为22.25%-23.24%,其中合丰42是国内育成的第一个半矮秆大豆品种,合农60是矮秆品种。这些品种是高油、矮秆大豆育种的宝贵种质。

The American soybean germplasm resources with high oil and dwarf were crossed with local soybean varieties,which were high yielding and wide adaptability by single cross,simple backcross and neutron.After successive directional selection,advanced methods of quality analysis and resistance evaluation,four new soybean varieties were bred,which were Hefeng 42,Hefeng 52,Hefeng 57 and Henong 60.Their oil content was 22.25%-23.24%,Hefeng 42 was the first semi-dwarf soybean variety in China,and Henong 60 was dwarf variety.They were all important germplasm in high oil and dwarf soybean breeding.
