摘要 采用绿色育种理念和现代选择与鉴定技术,以中国农科院引进材料P236(19)为母本,以新培育的自主创新的中间材料长治02-6502为父本进行杂交,培育出高产节水多抗小麦新品种长麦6789。在2015、2016年山西省中部晚熟冬麦组区域试验中,长麦6789两年平均产量为7 723.5 kg/hm2,比对照中麦175增产5.7%。该品种株型紧凑、杆壮抗倒、多抗广适、灌浆快落黄好,于2017年12月通过山西省农作物品种审定委员会审定,适宜在山西中部晚熟冬麦区种植。

Abstract Green breeding and modern selection and identification techniques were adopted. With P236(19) introduced by Chinese Academy of Agricultural Sciences material as the female parent and intermediate material Changzhi 02-6502 as the male parent, new wheat variety Changmai 6789 was cultivated which had high yield,water saving and multiresistance. In the regional experiments of late mature winter wheat group in central Shanxi Province in 2015 and 2016, the average yield of
