摘　　要：为满足黑龙江省畜牧业快速发展对优质高蛋白饲料的需求,黑龙江省农业科学院作物资源研究所在2009年以红04-26为母本,以苏啤3号为父本进行杂交,利用系谱法选育出饲用大麦新品种龙饲麦1号。该品种于2010-2013年经过F 1~F 4代选择性状良好的株行进行混合收获脱粒,2014年F 5代选择抗病、抗倒伏、农艺性状优异的单株进行收获脱粒,于2015年决选,决选代号为2015F 6-1582。2016年命名为龙饲麦1号进行产量鉴定,并于同年进行异地鉴定试验。2017-2018年完成黑龙江省北部和内蒙古自治区东北部地区的区域试验,两年两个地区平均产量分别为5104.6和4475.2 kg·hm^(-2),均比对照品种垦啤麦10号增产明显。龙饲麦1号品种出苗率高、分蘖力强、株高适中,品种籽粒较大,千粒重达42.7~52.2 g;籽粒呈黄色,粒形为长圆形;在黑龙江地区全生育期78~79 d,在内蒙古地区全生育期74~79 d,与对照品种同期成熟,属中熟型大麦品种。蛋白质含量17.31%,淀粉含量52.43%,为优质饲用大麦品种。在鉴定试验中表现出高产、稳产、适应性强的特点,对条纹病、根腐病及黄矮病均表现出较强抗性,在黑龙江省北部、内蒙古自治区东北部地区均具有较好的应用前景和大面积推广潜力。In order to meet the demand for high-quality and high-protein feed for the rapid development of animal husbandry in Heilongjiang Province,Crop Resources Institute of the Heilongjiang Provincial Academy of Agricultural Sciences selected and bred a new forage barley variety,Longsimai 1,in 2009 by crossing Hong 04-26 as the female parent and Supi 3 as the male parent using pedigree method.Longsimai 1 was selected for mixed harvesting and threshing in 2010-2013 after selecting rows with good traits from F 1 to F 4 generation.In 2014,the F 5 generation selected individual plants with excellent disease resistance,lodging resistance,and agronomic traits for harvesting and threshing.The final selection and breeding were carried out in 2015.The selection code was 2015F 6-1582.In 2016,it was named Longsimai 1 for yield identification,and an off-site identification test was conducted in the same year.Regional trials in Northern Heilongjiang and Northeastern Inner Mongolia was completed from 2017 to 2018.The average yields of the two regions in the past two years were 5104.6 and 4475.2 kg·ha-1,respectively,both of which showed a significant increase in yield compared to the control variety Kenpimai 10.The results showed that the Longsimai 1 had a high seedling emergence rate,strong tillering ability,moderate plant height,large grains,and a thousand-grain weight of 42.7-52.2 g.And the grain color was yellow and the grain shape was oblong,the full-life expectancy was 78-79 days in Heilongjiang region,74-79 days in Inner Mongolia region.It matured at the same time as the control,and was a medium-maturing barley variety.The protein content was 17.31%and the starch content was 52.43%,which was high-quality feed barley variety.In the identification test showed high yield,stable yield,strong adaptability characteristics,on the stripe disease,root rot and yellow dwarf disease have shown strong resistance,in the Northern Heilongjiang,Northeastern Inner Mongolia have a better prospect of application,with large-scale promotion potenti
