摘　　要：新麦21系新乡市农业科学院以偃展1号为母本,新麦9号为父本杂交,经后代系谱法连续选择培育而成的小麦新品种。新麦21属弱春偏冬性、高产、稳产、抗病、抗寒、中早熟品种。系谱分析表明,新麦21综合了双亲的优良性状,含有英国抗源和波兰、意大利小麦血缘,具有抗逆性强、综合性状优良及广泛的适应性等特点,适宜河南中北部、安徽省北部、江苏省北部、陕西关中、山东菏泽地区中高肥水、中晚茬地种植。2007-2008年国家黄淮南片春水组区试结果表明,该品种2a平均产量8319kg/hm2,比对照偃展4110增产4.4%。品质达优质中筋标准,蛋白质14.95%～15.04%,容重795～800g/L,湿面筋34.7%～35.7%,稳定时间2.3 min。Xinmai 21,a hybrid with Yanzhan 1 as female parent and Xinmai 9 as male parent,was bred by Xinxiang Academy of Agricultural Sciences through offspring pedigree successive selection.Xinmai 21 was a weak spring and winter side wheat variety of high and stable yield,disease resistance,cold hardiness,and early-middle maturity.Pedigree analysis showed that Xinmai 21 had good traits combined from both of parents,with British wheat anti-source and Polish and Italian wheat blood.The variety possessed characteristics of strong resistance,excellent comprehensive traits,wide adaptability and so on,suitable to be planted late in areas of high and middle fertilizer and water in north-central Henan,northern Anhui,northern Jiangsu,Guanzhong of Shanxi province,and Heze of Shandong province.The test results of 2007 and 2008 showed that the average yield of Xinmai 21 was 8 319 kg/ha,increased by 4.4% compared to the control,Yanzhan.The variety contained 14.95%-15.04% protein and its bulk density was 795-800 g/L.The variety possessed 34.7%-35.7% wet gluten and the stabilization time was 2.3 min.Therefore,Xinmai 21 met standards of excellent quality and medium gluten.
