| Outline of Final Research Achievements |
Accumulation structure of reserve substances and crop scientifical and/or cultivational evaluation were conducted for rice produced in several areas of Fukushima prefecture.
Amylose or protein content of milled rice in a certain cultivar differed even within a regional area, among regional areas and paddy fields, which was caused largely by the difference of cultivation management. For ultra-fine structure of cooked rice grain observed by scanning electron microscope in a certain cultivar, surface and peripheral layer structures were almost same among regional areas, while the difference was occurred among paddy fields as well as grains. In the middle and center portion of cooked rice grain, gelatinization structure was differed among paddy fields as well as grains, however, products of Aizu regions seemed to be advanced than the others.
There was no effect by radioactive rays on accumulation structure of reserve substances and ultra-fine structure of cooked rice grain.

| Academic Significance and Societal Importance of the Research Achievements |
品質がばらつくと指摘される福島県地域産の米は、品種の違いや気象・環境条件が異なる地域間差異に加えて、施肥・水管理等の栽培方法による差異が大きいことが明らかとなった。すなわち、栽培制御により品質や食味の高位安定化が図られる可能性が明示された。加えて、品質・食味の高位安定化をはかるためには、地域において適切な品種を選定し、オーダーメイド的な栽培制御技術の必要性が考えられた。したがって、社会的にきびしい状況に置かれている福島県産米の品質・食味の高位安定化による改善の端緒が示された。
