To provide a low-amylose Fagopyrum plant; and to reduce an amylose content, thereby improving the texture of the food including a Fagopyrum plant and improving the workability in the production of the food.SOLUTION: A Fagopyrum plant satisfies at least one of the following conditions: an amylose content being lower than that of the wild type by at least 8.0%; and an amylose content being 26% or less. Such a Fagopyrum plant is obtainable by mutating the gene of granule-bound starch synthase (GBSS).SELECTED DRAWING: Figure 3 【課題】低アミロースソバ属植物を提供する。またアミロース含有率を低下させることにより、ソバ属植物を用いた食品の食感、および食品製造時の作業性を向上させる。【解決手段】下記の少なくとも一方を満たす、ソバ属植物を提供する。アミロース含有率が、野生型に比較して少なくとも8.0%低い。アミロース含有率が、26％以下である。このようなソバ属植物は、顆粒性デンプン合成酵素（Granule-Bound Starch Synthase; 以下GBSS）の遺伝子を変異させることにより得られる。【選択図】図３
