摘　　要：分析2019—2024年安徽省审定粳稻的亲本来源、品种类型以及在区试中的农艺性状、产量、米质和抗性表现,研究安徽省粳稻品种选育和审定工作有待加强的方面。结果显示,迟熟中粳品种提高产量主要选育穗型较大且整齐的类型,早熟中粳品种选育穗粒兼顾的品种,晚粳品种应注重选育早生快发、分蘖力强而多穗类型的品种。We analyzed the parent sources,variety types,and agronomic traits,yield,rice quality and resistance performance of the Japonica rice approved in Anhui Province from 2019 to 2024 in the regional trials.We also studied the aspects of Japonica rice variety breeding and ap⁃proval work in Anhui Province needed to be strengthened.Results showed that for middle late season Japonica rice,we should mainly focused on breeding types with larger and uniform panicles to increase yield.Middle early season Japonica rice should prioritize varieties with balanced grain and panicle characteristics.Late Japonica varieties should emphasize the breeding of early⁃maturing,vigorous tillering and multi⁃panicle types.
