| Abstract: | Guicao 1(Lolium multiflorum) with quality and high grass yield was repeatedly selected from the reproductive population of Abeide (Lolium multiflorum) introduced by Guizhou Pratalcultural Institute and Guizhou Reproductive Ground of Forage Seeds. The total growth period, plant height at first-flower stage, plant height at boot stage, leaf length and leaf width of Guicao 1 is 235 d, 130 to 150 cm, 80 to 120 cm, 25 to 37 cm and 1 to 1.5 cm respectively. The fresh grass yield in the variety test was up to 6 71... |
