Songya 77 is a long-grain fragrant rice variety developed by Hunan Rice Research Institute through systematic breeding, with Yuzhenxiang as the female parent and Xiangyaxiangzhan as the male parent. This variety has the characteristics of suitable growth period, compact plant architecture, moderate plant height, fine quality, high and stable yield. It was registered in 2024 by Hunan Provincial Crop Variety Appraisal Committee. This paper introduced the breeding process, characteristics, important alleles and key cultivation techniques of Songya 77.
Key words： rice; fragrant rice; long grain; Songya 77
