Starch synthase IIIa (SSIIIa)-deficient rice mutant, that was completely absent in SSIIIa activity, and the parental Nihonbare were characterized to reveal the relationship between the structure of the endosperm starches and the rheological properties of its starch pastes. The length and width of raw rice grains of SSIIIa and Nihonbare were similar, but the cooked rice grains of SSIIIa became longer than Nihonbare. The characteristic force-strain curve on cooked rice grain of SSIIIa was showed brittleness. Changes in the pasting and rheological peoperties of SSIIIa were mainly caused by the structure of amylopectin and SSIIIa was thought to be useful food material as a domestic rice crop.

淀粉合成酶IIIa（SSIIIa）缺失的水稻突变体（SSIIIa活性完全缺失）和亲本日本晴的特征在于揭示胚乳淀粉结构与其淀粉糊流变学性质之间的关系。SSIIIa和日本晴的生米粒的长度和宽度相似，但SSIIIa的熟米粒比日本晴长。SSIIIa稻米的特征力-应变曲线呈脆性。支链淀粉的结构是引起淀粉糊化特性和流变特性变化的主要原因，是一种很有价值的食用原料。
