In 2024, we conducted screening trials on 24 rice varieties under the shrimp-rice co-cultivation model, focusing on evaluating the growth duration, yield, and resistance performance of each variety. The results showed that the unit yield of the tested varieties ranged from 421.6 to 696.7 kg/667 m², and the growth duration ranged from 108 to 136 days. Overall, the tested varieties exhibited good performance in terms of lodging resistance and disease resistance. After a comprehensive consideration of the yield, growth duration, and resistance performance of each variety, we believe that Quanliangyou 607, with its high yield but relatively long growth duration, is suitable for early planting under the local shrimp-rice co-cultivation model; while Hualiangyou 919, Bangliangyou 6118, and Wanliangyou 88, which have relatively high yields and shorter growth durations and show excellent overall performance, are suitable for planting as post-shrimp-harvest rice; and Xiadao 1, with the shortest growth duration, is suitable for planting in areas with special requirements for growth duration. The findings of this study hold significant reference value for the variety layout and promotion of rice under the shrimp-rice co-cultivation model in Xiantao City.
