大麻新品种'龙大麻1号'的选育

摘要

龙大麻1号是以山东省优质、高纤、抗逆性强的大麻地方品种鲁麻1号为母本,黑龙江省大麻地方品种五常40为父本进行杂交,通过单性选择育成.所内和异地鉴定、区域和生产试验表明该品种优质、高产、熟期适中、抗病、抗倒伏能力强等优点.2010年生产试验,原茎、长麻、全麻、种子产量分别达到9015.3kg/hm2、1259.2kg/hm2、1638.3kg/hm2和508.7kg/hm2,分别比对照增产11.0%、15.8%、14.7%和17.5%.长麻率18.0%,比对照高1.3个百分点;全麻率23.4%,比对照高1.6个百分点:纤维强度269N.%Longdama No.1 was bred from progeny of Luma No.1 × Wuchang 40 by unisexuality selection, Luma No.1 had some good characteristics such as high yield, superior quality and high resistance.The results of the regional test and production test showed that the variety had good characteristics including high fiber content, superior quality, disease resistance, lodging resistance and so on.In 2010, straw yield,long fiber yield, total fiber yield and seed yield were 9015.3kg/hm2, 1259.2kg/hm2, 1638.3kg/hm2 and 508.7kg/hm2, 11.0％,15.8％,14.7％ and 17.5％ more than the control's respectively.Long fiber content was 18.0％, 1.3％ more than the control's.Total fiber content was 23.4％ in the production test, 1.6％ more than the control's, fiber strength was 269N.
