Abstract：104 lines that was different types of water-saving and drought-resistant germplasm were cultivated. 45 new germplasm materials were bred， whose the ability of water saving and drought-resistance has been significantly improved， and their production were not reduced， which quality to meet national quality standards and saved water more than 30%.13 new germplasm lines with resistance to drought and rice blast resistance were cultivated； 14 restore lines with resistance to drought and brown planthopper resistance were bred； 9 restore lines of water-saving showed the resistance to rice blast，while 2 restore lines were confirmed with drought resistance， brown planthopper resistance and rice blast resistance.Moreover，we are actively promoting the application and demonstration of new water-saving and drought-resistant rice varieties.Such as Huhan No.3，Huyou No.2，Lvhan No.1， Jingganghandao No.1， Hanyou No.113，03you No.66.

Key Words：Water-saving and Drought-resistance；High Nutrient Efficiency；Disease and Insect Resistance；Green Super Rice
