    Abstract: A pleiotropic UGPase1 gene which causes chalky endosperm and male-sterility by substituting mono nucleotide in the UGPase1 gene is provided. A plant forms chalky endosperm by mutating a rice-derived UGPase 1 gene which comprises base sequence of the sequence number 1(SEQ ID NO:1). The amylase content, gel consistency or magnesium/potassium ratio of chalky endosperm is reduced comparing a normal endosperm. The protein content, lipid content, magnesium and calcium content or fatty acid total content is increased comparing the normal endosperm. The starch structure of chalky endosperm has more straight chain amylase and an amylopectin having more branches. The UGPase1 gene has pleiotropic property and causes chalky endosperm and male-sterility.
