摘要

：为了阐明水稻品种的适宜类型和高产形成机制，我们主要分析了长江两季稻北缘晚季籼稻和粳稻的产量差异。实验于2018年至2019年在安徽庐江进行。通过当地栽培的17个籼稻和17个粳稻品种（系），比较分析了籼稻和粳稻在产量和产量构成、干物质积累和生育期方面的差异。结果表明，总体上为高产粳稻品种选择不同穗型，以进一步开发产量潜力。

Suitable varieties and high-yielding population characteristics of late season rice in the northern margin area of double-cropping rice along the Yangtze River

: To clarify the suitable types of rice varieties and the mechanism of high yield formation, we mainly analyzed the yield difference between indica and japonica rice in late season in the northern margin of the double-cropping rice along the Yangtze River. The experiment was conducted from 2018 to 2019 in Lujiang, Anhui province. The differences of yield and yield components, dry matter accumulation, and growth period between indica and japonica rice were compared and analyzed through 17 indica rice and 17 japonica rice varieties (strains) which were cultivated in this local area. The results showed that the overall for high-yielding japonica rice varieties with different panicle types in order to further develop the yield potential.
