In order to screen for high-quality and high-yield wheat stubble rice varieties suitable for promotion and cultivation in the southwestern region of Anhui, this study selected 12 varieties, including Longliangyou 8612 and Longliangyou 5438, and one control variety (Fengliangyou No.4) for variety comparison experiments. Comparative analysis was conducted from the aspects of growth period, agronomic traits, resistance, yield and yield composition factors. Four varieties with moderate growth period, good lodging resistance, and high yield and coordinated yield components were selected under the climatic conditions of that year, namely Quanyou 1606 (yield: 9 758.3 kg/hm2), Quanyou 822 (yield: 9 586.2 kg/hm2), Huiliangyou 898 (yield: 9 568.9 kg/hm2), and Yinliangyou 606 (yield: 9 368.9 kg/hm2), which could be promoted and planted as wheat stubble rice varieties in the region of research.
