(Polygonaceae) highly accumulates soluble oxalate in leaves. Animals should restrict their intake of oxalate because high level of oxalate causes the poisoning. Therefore, well growing in the meadow is a target of weeding. In this study, we aimed to develop a low oxalate plant that can be used as a pasture by radiation breeding. Plants from seeds irradiated with several doses of rays were used to analyze the radiation effect on oxalate content and other metabolite profiles. As a result, the oxalate content in leaves was decreased by -ray irradiation. Plants with low oxalate content commonly contained increased level of amino acids and reduced level of organic acids.
