Jigeng 830 is a round-grain fragrant rice variety developed by the Rice Research Institute of Jilin Academy of Agricultural Sciences. It was bred by crossing the high-quality round-grain fragrant rice line Ji B2008-1853(Yunlangxiang, female parent) with the high-quality disease-resistant variety Tongke 17(male parent), followed by multi-generational pedigree selection and molecular marker-assisted selection(MAS) for fragrance genes. This variety exhibits advantages of high quality, high yield, strong stress resistance, and wide adaptability. It was approved by the Jilin Provincial Crop Variety Approval Committee in 2020(Approval No.: Jishendao 20200035). This paper introduces the breeding process, agronomic characteristics, important alleles, and key cultivation techniques of Jigeng 830.
