Abstract:Hybrid rice varieties provided by our research group were used as tested varieties, and Y Liangyou 9918 and Zhunliangyou 608 were used as control varieties. The growth period, the flexural resistance in the main season, the grain yield in the main season, the grain quality in the main season, the ratoon rate, the grain yield in the ratoon season, and the grain quality in the ratoon season were collected in the random experiments as indicators. In two consequent years, 2017–2018, the varieties suitable for ratooning were screened in Changsha, Hunan. The results of two years showed that when Liangyou 389 and Wangliangyou 889 were used to ratoon (stubble height 30 cm), the growth period in the main season were not more than 140 d. Their flowering stage in the ratoon season were before the September 20th, and their mature stage in the ratoon season were in late October. The flexural resistance of them were higher than that of the control varieties. The grain yield in the main season of them were higher than that of the control varieties. The ratoon rate of them were higher than that of the control varieties. The grain yield in the ratoon season of them were higher than that of the control varieties. The grain quality in the ratoon season of Liangyou 389 was scored second grade that was consistent with the control varieties. The grain quality in the ratoon season of Wangliangyou 889 was scored third grade. Therefore, Liangyou 389 and Wangliangyou 889 were suitable for ratooning in the region of Changsha. The grain quality in the main season of the tested varieties didn’t meet the grain quality rating standard, which is mainly due to the lower head rice percentage and higher chalkiness.
