Abstract: The high quality rice varieties with validation and candidate in Hunan Province and high quality rice varieties from Guangdong Province and India were grew in Changsha. The rice quality and agronomic characteristics of different high quality rice varieties were analyzed. Huanghuazhan, Xing 2, Xiangwan 10, Xiangwan 13, Xiangwan 17, Huangsizhan, Huangguangzhan, Xiangyaxiangzhan and Nongxiang 26 showed good rice quality and high yielding. The study proposed the object of the high quality rice variety: chalky rice rate≤5%, chalkiness degree≤1%, grain length≥6.5 mm, length-width ratio of rice≥3, amylose content 13%~18%, gel consistency ≥50 mm, aroma, plant height 110~120 cm, effective panicle number per plant≥10, seed setting rate≥80%, 1000-grain weight about 25 g, and the high quality rice variety should show rice blast resistance, lodging resistance and good for mechanical harvest.
