Abstract: In this paper, the basic characteristics of Quanyou series of high-quality rice varieties, which were suitable for planting in Hubei ecological areas （except Wuling Mountain Area） and approved by the provincial government in 2020, were analyzed. The rueslt showed that, there were 12 suitable rice varieties. Viewing from the main body of variety breeding, the varieties mainly selected by enterprises;Quanyou series of high quality hybrid combinations generally had large grains per panicle and high seed setting rate, but the effective panicle number was general, and the yield per panicle contributed more in unit yield. Quanyou series of high quality hybrid combinations could be selected and bred varieties with good rice quality and blast resistance, but breeding varieties resistant to bacterial blight and brown planthopper remained to be strengthened.
