摘　　要：将"东野/栽培稻"杂交后代不同品系的种子直接播种在20 cm水深的量筒内,然后分别在15℃和30℃恒温条件下进行处理。结果筛选出在低氧条件下具有萌发整齐度高、受温度变化影响较小和芽鞘伸长能力较强等特点的品系"907676-1",可供在直播水稻品种的遗传改良中应用。The different strains seeds of hybrid offspring from ＂Dongxiang wild rice/cultivated rice＂ were directly sowed into 20 cm deep water at two different constant temperatures （ 15 ℃and 30 ℃ ）. Finally, we found that under low oxygen condition, ＂907676 -1＂ had high germination uniformity, little influence by temperature changes, and strong bud- sheath elongation ability, therefore it could be used for the genetic improvement of direct - sowing rice.
