摘要
黑龙江省农业科学院佳木斯分院1994年引进美国矮秆大豆品种资源20余份,鉴定筛选出优异矮资源3份（hobbit、sprite87和elf）,直接或间接配制杂交组合369个,育成大豆新品种（系）7个,其中高油品种（系）6个（合丰42、合丰52、合丰57、合农60、合农64和合交08-1800）,油分含量变化幅度为21.90%-23.57%;矮秆、半矮秆类型品种2个（合农60和合丰42）;早熟1个、中早熟品种1个及中熟品种（系）5个。育成品种在主要农艺性状、产量、品质、抗病性及适应性等重要性状上有较大改进与创新,达到了预期的育种目标,结果表明美国矮秆资源（hobbit、sprite87和elf）是品种改良的优良种质,可在今后杂交育种上广泛应用。
More than 20 dwarf soybean germplasm were introduced from USA in 1994 by Jiamusi Branch of Heilongjiang Academy of Agricultural Sciences and 3 excellent individuals were selected（ hobbit,sprite87 and elf） to make up 369 crosses through direct or indirect methods,based on which seven new soybean varieties（lines） were bred,including 6 high oil content soybean varieties（lines）（ Hefeng 42,Hefeng 52,Hefeng 57,Henong 60,Henong 64 and Hejiao 08-1800）,which oil content ranged from 21. 90% to 23. 57%. In the seven new soybean varieties（lines）,there were two dwarf or semi-dwarf varieties（Henong 60 and Hefeng 42）,1 early-maturing,1 mid-early maturing and 5 mid-late maturing varieties. It had great improvement and innovation on main agronomic traits,yield,quality,disease resistance and adaptability,and achieved the expected goal. The result show that the USA dwarf germplasm（hobbit,sprite87 and elf）are excellent and can be widely applided in cross breeding.
