Liliangyou 3822 is a novel indica hybrid rice variety that exhibits disease resistance, high yield, lodging resistance, and late maturity. It employs a self-selected two-line sterile line, Li 38S, and a self-selected restorer line, R22. This variety was subjected to a regional test of indica late-maturing groups in the middle and lower reaches of the Yangtze River in 2020. The results demonstrated that the average yield of the variety was 9.95 t/hm2, which was 10.67% higher than that of the control Fengliangyou No.4, indicating a highly significant yield increase. In the continuous test in 2021, the average yield was 9.74 t/hm2, representing a 6.52% increase over the control, which also exhibited a significant increase. Finally, the average yield of the two years’ regional test was 9.84 t/hm2, which was 8.58% higher than that of the control. In the 2021 production test, the average yield of the variety was 9.32 t/hm2, which was 12.19% higher than that of the control, indicating a remarkably significant yield increase. In 2022, the variety was validated by the National Crop Variety Approval Committee (GSD 20220143). |
