摘　　要：化诱446大豆是应用化学诱变剂DES及PYM复合处理冀豆4号湿种子经累代选择鉴定育成的新品种。该品种具有产量高、品质优、抗病、抗倒性强等优点。经3年品比试验,2年的区域试验,1年的生产试验均比对照品种冀豆7号增产显著,居参试品种首位。适宜在河北省中南部及同类气候区夏播推广应用。Chemical mutated 446, a new soybean variety, was developed by using strong mu-tagen DES and PYM to treat the wet seed of soybean Jidou 4, then through the processes ofcumulative selection, appraisal and cultivation. This new variety has the characters of highproductivity, good quality, high resistance, anti-lodging ability etc. The results from three-years' variety testing, two-years' regional experiments and one-year's production ex-periment showed that the yield of 446was significantly higher than that of the controlled va-riety Jidou 7, and it produced the highest yield among the tested varieties. 446 is suitable togrow in the central and southern part of Hebei province and other regions with the samecharacters for summer sowing.
