During the whole growing season, deep-water management was carried out to compare the growth period, lodging resistance, yield, and quality of each variety (line) . [Results]: Nanjing 5718, Xudao No.9, and Sidao No.16 had compact plants, strong lodging resistance, and average rice quality. Huaidao No.20 and Sidao No.17 had strong tillering ability and fast grain filling, with yields of 9 985.39 and 9 805.43 kg/hm², respectively, which were significantly higher than most varieties. Sidao 301 had higher yield of 9 614.49 kg/hm², with large, gleaming and great quality rice grains but longer growth period. [Conclusion]: Nanjing 5718, Xudao No.9, and Sidao No.16 had high promotion value in rice and shrimp co-cropping in Northern Jiangsu, and could be used as suitable japonica rice varieties with good quality.
