New Endosperm Mutants Modifying Starch Characteristics of Rice, Oryza sativa L.

Few genes which control the proportion of amylose and amylopectin components in starch granules have been found in rice, since waxy alleles were detected and located on Chromosome 6.G,o> Recently, several kinds of endosperm mutants of rice were successfully induced by Okuno,10> and Satoh and Omura.1 3 > The present report deals with newly induced mutants which are characteristic of the modification of starch properties in the endosperm of rice grains.
