| Research Abstract |
About 500 rice cultivars including native strains were cultivated in the university paddy field, Shobara, Hiroshima, and their characteristics such as heading date, maturing date, plant height, total weight, grain weight, and shape, protein content and amylose content of hulled grain were surveyed. The pigment expression of black rice was influenced by environmental conditions, such as temperature after heading and harvest time. Red rice and black rice showed anti-bacterial effects. Anti-oxidative activity and polyphenol content was in the order of red rice > black rice > green rice= white rice. The report “Protection of rice field in Japan using various rice cultivars: Agronomic characteristics and utilization case of rice cultivars that have been collected by Prefectural University of Hiroshima” was published.
