Abstract: In order to identify and evaluate the yield, stability, adaptability, stress resistance, rice quality and other important traits of Yexiangyou 6813, participated in the regional trial of middle rice group in Fujian Province from 2018 to 2019. The results showed that Yexiangyou 6813 has medium yield, general stable yield, wide adaptability, rice blast susceptibility, and is suitable for one season of rice in Fujian Province. The yield structure analysis showed that the number of grains per panicle had the largest contribution rate to yield increase, the number of panicle per unit area had a larger contribution rate to yield increase, and the thousand grain quality and seed setting rate had a smaller contribution rate to yield increase. Therefore, the key of high yield cultivation of Yexiangyou6813 is to focus on large ears on the basis of a certain number of ears.
