摘要
以旱稻65(H65)及其与稗草远缘杂交后代YF2-1为材料,比较了两者之间的芽期、苗期的耐干旱胁迫能力的差异。结果表明:在干旱胁迫条件下,YF2-1的芽期抗旱性以及苗期生长状况显著强于H65。由此可见,利用稗草有效基因的渗入是提高旱稻抗旱能力的有效途径。
H65 （Oryza sativa L. ） ,an aerobic rice cuhivar, and YF2- 1, a progeny derived from distant crossing between H65 and long-awn-barnyard grass （Echinochloa caudata）, were used to study drought resistance at budding and seedling stages. The results showed that the drought resistance of YF2-1 was significantly higher than H65 at both stages, indicating that the introduction of Long-awn-barnyard grass＇genes into aerobic rice would be an effective way to improve drought resistance.
