Abstract:
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,sprite87and 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,sprite87and elf)are excellent and can be widely applided in cross breeding.
