| 摘 要： | 盆栽试验测定了22份野生稻和9份非洲栽培稻对无芒稗的抑制效果。发现野生稻DY12 和DY16存在显著的抗性作用，它们对无芒稗的苗数抑制率分别达到46.1%和47.0%，对无芒稗植株鲜重抑制率分别达到66.8%和72.3%。非洲栽培稻FZ24也表现出良好的防治无芒稗效果，无芒稗苗数抑制率和植株鲜重抑制率分别达到41.7%和65.7%。 |

| Abstract: | In a pot experiment, 22 wild rice and 9 African rice cultivars were evaluated in bioassay for resistance function on barnyardgrass Echinochloa crus galli (L.) Beauv. var. mitis (Pursh) Peterm.]. Wild rice DY-12 and DY-16 had excellent resistance function with reduction in barnyardgrass seedling number being 46.1% and 47.0%, and in barnyardgrass plant fresh weight being 66.8% and 72.3%, respectively. African cultivar FZ 24 also had good resistance effect on the barnyardgrass with the seedling number reduction of 41.7% and plant fresh weight reduction of 65.7%, respectively. |
| Keywords: | wild rice African cultivar Echinochloa crus galli (L ) Beauv var mitis resistance to weed |
