在已筛选出的水稻形态性状突变系中，发现NM 67的谷蛋白含量较低，而醇溶谷蛋白含量较高。该突变体为半矮秆部分不育系，抽穗前叶片变黄。通过与日本正成回交的遗传分析表明：（1）谷蛋白含量低的性状总是伴随着醇溶蛋白含量高的性状，（2）谷蛋白含量低的性状是由谷蛋白含量高的性状引起的，（3）谷蛋白含量高的性状是由谷蛋白含量低的性状引起的，（4）谷蛋白含量高的性状是由谷蛋白含量高的性状引起的，（5）谷蛋白含量低的性状是由谷蛋白含量高的性状引起的，（6）谷蛋白含量高的性状是由谷蛋白含量高的性状引起的。（和高醇溶蛋白）性状似乎由一个显性基因表现;（3）突变体的半矮秆、低育性和叶片早黄化可能是由一对不依赖于蛋白质含量基因的隐性单基因控制的，也可能是多效性。NM 67的蛋白质性状与半矮秆、低育性遗传分离，从杂交后代中获得了形态性状与原品种相当的低谷蛋白、高醇溶蛋白新品系。讨论了该品系作为低蛋白水稻品种的可能性。
Among the mutant lines of rice that have been selected for morphological characters, one line, NM67, was found to have a low content of glutelin and a higher content of prolamine in its seed protein than other Japanese cultivars. This mutant is a semi-dwarf and partially sterile line, and its leaves turn yellow before heading. Genetic analysis after backcross to the original cultivar, 'Nihonmasari', revealed the following: (1) the character of low glutelin content was always accompanied by the character of high prolamine content; (2) the low glutelin (and high prolamine) character seemed to be manifested by a single dominant gene; and (3) semi-dwarfness, low fertility and early yellowing leaf of the mutant, which might also be pleiotropy, were controlled by a single recessive gene independent of the gene for protein content. The protein character of NM67 was genetically separated from semi-dwarfness and low fertility, and a new line having low glutelin content and high prolamine content with normal morphological characters comparable to those of the original cultivar was obtained from the progenies of the cross. The possible use of this line as a low protein rice cultivar is discussed.
