Average yield of conventional indica rice 463.35 kg/667 m2, three lines Indica hybrid rice 539.70 kg/667 m2, two lines Indica hybrid rice 557.03 kg/667 m2, conventional japonica rice 584.80 kg/667 m2, japonica hybrid rice 629.95 kg/667 m2. Quality compliance rate of Japonica rice（58.78%） was significantly better than indica rice（39.08%）, conventional rice（59.40%） better than hybrid rice（38.30%）. Rice quality of hongke 79, jinongda 878, jinsui 9, taiyou 390, wuyouhuazhan, huang huazhan and yueqixinzhan are better. Less varieties is with excellent comprehensive performance resistance.
