糯小麦品系TN-1的品质性状分析

    Analysis for Grain Quality Characters of the Waxy Wheat Line TN-1

    • 摘要: 测定了引进糯小麦品系TN-1的直链淀粉和籽粒全蛋白质的含量。结果表明,TN-1的直链淀粉质量分数低于1%,与糯米相似;全蛋白质量分数为18.00%,且含小麦独有的面筋蛋白,具有独特的品质。TN-1的籽粒糯性由3对独立的隐性基因支配,并就糯小麦的应用前景进行了分析。

       

      Abstract: The contents of grain amylose and protein in waxy wheat line TN-1 and non-waxy wheat line T531 were tested. The grain of TN-1 contained low amylose (0.89%) similar to glutinous rice and high protein (18.00%) as well as gluten similar to T531, thus possessed the particular quality. The results also showed that three pairs of recessive genes controlled waxy endosperm of TN-1 independently. The prospect of applying waxy wheat was also discussed.
