| Abstract: | A2003,a new Lolium multiflorum line,was bred from an introduced annual ryegrass variety by using single-plant 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/667m2,19.6% and 12.3% higher than the original population(CK1) and Guicao 1(CK2) and the average seed yield was 54 kg/667m2,11.3% and 10.3% higher than CK1 and CK2 in the variety test respectively.The average fresh grass,dry grass and seed yield of A2003 were 5 390.7 kg/667m2,730.3 kg/667m2and 53 kg/667m2,19.29 kg/667m2,17.43 kg/667m2and 14.39 kg/667m2higher than Guicao 1 in the production test respectively.A2003 can be planted on the winter fallow fields in Guizhou. |
