摘要
冬小麦新品种汾4439是以晋麦66号为母本、忻9152为父本进行有性杂交育成的。在2004—2006年山西省中部晚熟冬麦区高水肥区域试验中，2年折合平均产量5944．5kg／hm2，比对照京冬8号增产9．1％；在2005。2006年山西省中部晚熟冬麦区高水肥生产试验中，平均产量为5239．5kg／hm2，比对照京冬8号增产6．0％。苗期和成株期感条锈病和白粉病。子粒含粗蛋白（干基）16．41％，湿面筋32．80％，沉降值22．40ml，千粒重45g左右，容重786g／L。适宜在山西中部和全国北部冬麦区高水肥地种植。
Fen 4439 was selected from the progeny of the cross Jinmai66/Xin 9152. The average yield in advanced fertility regional test of late - maturing winter wheat area is 5 944.5 kg/hm2,9.1% higher than Jingdong 8, in Shanxi province from 2004 to 2006 and the average yield in advanced fertility regional test is 5 239.5 kg/hm2 ,6.0% higher than Jingdong 8 from 2005 to 2006. It infected stripe rust and powdery mildew during seedling and adult stage. The seed contains crude protain 16.41%, wet gluten 32.80%, with sedimentation value of 22.40 ml, 1 000 - grain - weight about 45 g, natural weight of 786 g/ L. It is suitable to grow in advanced fertility region in center of Shanxi province and northern China.
