Abstract：

    Rice (Oryza sativa L.) is one of the most important staples in the world. Seventy five percent of the world’s rice is grown under flooded, or submerged conditions, it is also one of the biggest users of the world’s developed freshwater resources. Water for agriculture, especially for irrigated rice production, is becoming increasingly scarce due to greater urban, domestic and industrial demand. This research aims to obtain a proper method for the development of rice varieties can maintain or increase rice production under the situation of facing decline water availability. In 2013~2013, a total of 8 new combinations were crossed, 9 new F1 generation were developed, a total of 35 strains were selected out in F6 generation for observation tests. A total of 11 strains that allow rice production to be maintained or increased in the face of declining water availability.
