摘要
以引进的一年生黑麦草为原始材料,采用单株混合选择法,经过近10年的选育,育成新品种一年生黑麦草A2003。该品种经品比、区域试验以及在生产上大面积多点试验示范,鲜草、干草、种子产量均高于对照品种,且达到显著水平。是适应贵州省冬闲田土种植的优良牧草品种。
A2003, a new Lolium multiflorum line, was bred from an introduced annual ryegrass variety by using singleplant bulk selection method after ten years. The growth period in variety, regional and production tests was 206d to 209d, 200d to 234d and 211d to 214 d separately. The average fresh yield of A2003 was 4719 kg/667m^2 , 19.6% and 12.3% higher than the original population （CK1） and Guicao 1（CK2） and the average seed yield was 54 kg/667m^2 ,11.3% and 10.3% higher than CK;and CK2 in the variety test respectively. The average fresh grass, dry grass and seed yield of A2003 were 5 390. 7 kg/ 667m^2 , 730.3 kg/667m^2 and 53 kg/667m^2 , 19.29 kg/667m^2 , 17.43 kg/667m^2 and 14.39 kg/667m^2 higher than Guicao 1 in the production test respectively. A2003 can be planted on the winter fallow fields in Guizhou.
