영문 초록

High protein mutant No.398 (M_9 in 1973) was obtained from X-rayed Hokwang variety, and their grain characters were examined. The protein content of mutant No. 398 was increased 30% than that of mother variety. Besides the protein content, heading date was 25 days earlier and culm length was shortened 20㎝. Grain size and shape, weights of embryo and endosperm were similar to the control variety, while protein content of embryo of high protein mutant line was higher. Although the protein amount of embryo in the mutant was higher, it is negligible because in rice the endosperm was more than 35 times heavier than the embryo. The increase of protein in No.398 is attributable to the increment of protein in the endosperm. The mutant has more protein than mother line in the peripheral starch layer of endosperm. In developing grain the difference of protein amount per grain in mutant line was outstanding from three weeks after heading.
