| 摘 要： | Yields in the irrigated rice areas have improved remarkably over the last three decades. Farmers with access to assured water supply have adopted improved varieties, resulting in higher yields and improved income in rural areas. In contrast, yields remain low in the vast rainfed areas that are associated with higher levels of poverty. A few improved varieties have spread in these areas, but abiotic stresses such as drought and submergence prevent farmers from realizing their yield potential. Stress tolerant versions of these varieties are urgently needed to improve the standard of living and stabilize household food supplies. It has been found that tolerance to a number of abiotic stresses is controlled by a few QTLs of large effect, and that incorporation of these QTLs into the high yielding varieties could make a significant impact in stabilizing the yields of these varieties in stress-prone areas （Mackiil, 2006）. Submergence tolerance provides a good example of how marker assisted selection can be very effective to develop improved varieties for the rainfed lowlands.
