The genetic analysis of the low amylose content mutants YM1, YM2, P152, P153, and P154 induced fromjaponica rice Hexi 4 was cartted out. The recessive genes conditioning lower amylose content in the low amylose content mutants are alleies each other and nonallelic to the wx locus. The segregation of F2 of the crosses between low amylose contentmutants and YM1 with higher amylose content (10. 50%) fits the inheritance mode of single gene. The gene conditioninghigher amylose content is dominant to lower amylose content.
