优质旱地春小麦新品种甘春25号的选育及栽培技术研究

优质旱地春小麦新品种甘春25号,原代号A005—1,为甘肃农业大学与会宁县农牧局合作,以会宁15号为母本,五月黄为父本杂交,历时12年(1999～2011年)选育而成。2011年12月31日通过技术鉴定。2012年1月9～12日经甘肃省农作物品种审定委员会审定定名为甘春25号。该品种丰产性好,品质优,抗旱、抗病、抗倒性强,千粒重高,成熟落黄好。2009、2010年2年22点(次)国家西北春麦旱地组区域试验中,折合产量平均3 185.40 kg/hm2,较统一对照定西35号增产9.06%,2011年参加国家西北春麦旱地组生产试验,5点(次)均表现增产,折合平均产量1 936.35 kg/hm2,较统一对照定西35号增产18.01%,居参试材料第1位,增产显著。2010年在干旱半干旱地区对甘春25号进行了适宜密度和施肥量的研究,当种植密度为375万株/hm2、磷酸二胺施量为96 kg/hm2时,产量最高,为1 985.69 kg/hm2。

Study on Breeding and Cultivation Technology of High-quality Dryland Spring Wheat Variety Ganchun No.25

High-quality dryland spring wheat variety Ganchun No.25,the original code is A005-1,selected by Gansu Agricultural University and Huining Agriculture and Animal Husbandry Bureau with the parental combination of Huining No.15 and mature of May for 12 years(1999-2011),passed technical appraisal in December 31,2011 and named Ganchun No.25 by Gansu Provincial Crop Variety Approval Committee during January 9-12,2012.This variety has high productivity,good quality,drought tolerance,disease resistance,lodging resistance,high grain weight,mature yellowing.The average yield is 3 185.40 kg/hm2,more than CK(Dingxi 35) by 9.06%,in regional trial from 2009 to 2010,1 936.35 kg/hm2 and more than CK(Dingxi 35) by 18.01%in production demonstration in 2011.The study on Ganchun No.25 of suitable density and amount of fertilizer in the arid and semi-arid regions showed that when planted density is 3.75 million plants/hm2,(NH4)2HPO4 is 96 kg/hm2,the yields is the highest reached 1 985.69 kg/ hm2.
