本研究では、東北糯149号、フクヒビキ、奥羽368号、朝紫、コシヒカリを用いて米粒の形態的特性および米粒2粒からのデンプン分子構造の解明を試みた。形態的特性やデンプン分子量分布には、親間の中間の形質を示すものが見られた。アミロースに関しては、定法と比較してGPC法では低い値を示すが、似た傾向を示した。The rice is a one of most useful cereal food, and has tried to breed improvement. The rice that have new phenotype is necessary for a long time because of life cycle. And rice grains have many genotype and phenotype, so, we need to many labors to select the rice grain that have better phenotype. We try to solve this problem using alkaline solution, but they were damaged and lost the molecular information. We will plan to make the procedure that　more　miｌd treatment to solve starch granule and analysis by a half part of rice granule, and the other will using to plant cell cultunng, at goal. And we compare to amylose content by this way and general method.
