Abstract: To advance the high-quality development of shrimp-rice industry in Qianjiang City, Hubei Province, 19 new rice varieties independently bred by the Institute of Food Crops, Hubei Academy of Agricultural Sciences were collected, and a systematic screening experiment under the local shrimp-rice co-cropping regime was conducted. After comprehensive evaluation, two high-yield and high-quality shrimp rice varieties, Yangxianyou 77 and E Liangyou 2300, were screened out from the late-maturing varieties. Among them, the yield of Yangxianyou 77 reached 12 483.30 kg/hm; ², which was 56.54% higher than that of the control Huanghuazhan, and the rice quality reached the third grade of the ministry standard under extreme high temperature conditions. The yield of E Liangyou 2300 was 10 348.50 kg/hm; ², which was 29.77% higher than that of the control Huanghuazhan, and the rice quality also reached the third grade of the ministry standard under extreme high temperature conditions. A high-yield and high-quality shrimp rice variety Yaliangyou Meixiangxinzhan was screened out from early maturing varieties. The yield was 11 056.50 kg/hm; ², which was 38.64% higher than that of the control Huanghuazhan. The rice quality reached the third grade of the ministry standard under extreme high temperature conditions. In addition, the yield of E Nongxiang 11S/HD227 was 11 060.25 kg/hm; ², which was 38.69% higher than that of Huanghuazhan.
