摘　　要：对一年生黑麦草A2003与原始群体及贵草1号在贵州4个不同区域的生育期特性、产量性状、再生速度、茎叶比、株高及鲜干比等方面进行了综合观测比较。结果表明:A2003平均鲜草产量分别比原始群体(CK1)及贵草1号(CK2)增产12.73%和12.59%,干草产量分别比原始群体及贵草1号增产14.57%和14.71%,种子产量分别比原始群体及贵草1号增产23.08%和9.09%。一年生黑麦草A2003是适合在贵州种植的品种。Three ryegrass lines or varieties, A2003, the original population of A2003 （CK4） and Guicao 1（CK2）, were tested in 4 different regions to compare their growing characteristic, yield, regeneration rate, ratio of stem to leaf, plant height and ratio of fresh to dry weight. The results showed that the fresh grass yield, dry grass yield and seed yield of A2003 was 12.73% and 12.59%, 14.57% and 14.71%, and 23.08% and 9.09% higher than CK1 and CK2 respectively. A2003 should be popularized in Guizhou.
