摘 要 ：以优质粳型糯稻苏御糯为供体，品质较差的籼稻桂朝2号为轮回亲本，构建了BC₂F₄群体，通过发展分子标记，研究了淀粉合成相关基因Wx、Sbe1、Sbe3、Isa、Pul、SssⅠ等对稻米淀粉RVA谱特征的影响。结果表明Wx基因对RVA谱8个特征值的表现均起主要作

Abstract:RVA profile has been frequently used to evaluate rice cooking and eating quality. Starch content is up to 90% in milled rice, indicating that starch-synthesizing genes may have a correlation with rice cooking and eating quality. In order to investigate the effect of the starch-synthesizing genes
