Two mutants for rice storage protein in the starchy endosperm, 13b-l. and 57-H, were crossed with their original variety, Kinmaze. From the results obtained in the F1 and F2 seeds, it was concluded that 13b-l. and 57-H are controlled by single recessive genes, which were designated as esp-1 and esp-2, respectively. The SDS-PAGE indicates that both mutant genes are regulatory genes for the protein bodies. The segregation ratio in F2 of the cross between esp-1 and trisomic type F and the cross between esp-2 and trisomic type G fitted that of a trisomic segregation. These results suggest that esp-1 and esp-2 are located on chromosomes 10 and 9, respectively.
