Abstract: Yexiangyou 676 is a disease-resistant and high-quality fragrant three-line medium indica hybrid rice variety bred by the Rice Research Institute of Fujian Academy of Agricultural Sciences. This variety had high yield, with an average yield of 8 612.2 kg·hm⁻² in the two-year regional trials, which was 8.9% higher than that of the control Eryouming 86. The average yield in production trials was 9 060.0 kg·hm⁻², an increase of 10.4% compared to the control Eryouming 86. The comprehensive evaluation showed that it was resistant to rice blast disease, and the rice quality reached the C grade high-quality rice standard issued by the Ministry. The rice had good taste and high rate of polished rice, making it suitable for producing the high-quality and upscale rice. In order to systematically summarize the high-yield and lodging-resistant cultivation techniques of Yexiangyou 676, the differential analysis of yield and lodging resistant traits in different plots under different nitrogen and potassium application levels and soil drying methods was conducted based on the main characteristics and the related genes of its excellent traits carried by Yexiangyou 676. Based on the experimental results, the "one low and three more" high-yield and lodging-resistant cultivation technique suitable for Yexiangyou 676 was determined, which was centered on "low nitrogen, more potassium, more base fertilizer, and reasonable moisture control", providing technical support for the promotion and application of this variety in production.
