本项目运用遗传学的原理,根据基因重组、累加、互补等遗传效应,采用有性杂交的方法,以中熟丰产、节间短、结荚密、秆强的中间材料合交8009-1612[(黑河54×阿姆索伊)×黑河54]为母本,与中早熟、秆强、丰产性好的绥81-272为父本进行杂交,成功地育成了高产稳产、优质、适应性好的大豆新品种合丰35号,1994年黑龙江省农作物品种审定委员会审定推广。1997年经内蒙古自治区农作物品种审定委员会认定推广。该品种为亚有限结荚习性,主茎发达,植株较高大繁茂,秆强,节间强,有分枝,结荚密,三、四粒荚多,叶 This project uses the principle of genetics, according to genetic recombination, accumulation, complementarity and other genetic effects, the use of sexual hybridization methods to mid-ripe high yield, short internodes, pod dense, stalk strong intermediate material 8009-1612 [ (Heihe 54 × Amoyei) × Heihe 54] were used as the female parent to cross with the parents of early maturity, strong stalk and high yield of Sui 81-272, which successfully bred high yield, good quality and good adaptability Hefeng 35 new varieties of soybean, Heilongjiang Province in 1994 approved the approval of crop varieties to promote. In 1997 by the Inner Mongolia Autonomous Region Crop Variety Approval Committee to promote. The species is sub-limited to the pod habit, the main stem developed, tall and lush plants, stalks strong, internodes strong, branched, pod dense, three or four pods and more leaves
