The significance of genetic stability and bio-safety environment has been recently recognized by many GM plants. This study was to evaluate the GM stability of transgenic rice and to identify the environment variance. The GM rice of vitamin A -enriched rice and four check cultivars were analyzed the data on agronomic characters and principal component for 2009-2011 in large-GM crop field. Cultivation environment was conducted in the large-GM field and greenhouse to determine grain characters. In this experiment, there was no significant difference in agronomic characters between GM rice of vitamin A-enriched rice and a donor plant, Nagdong. Related to grain characters, grain appearance and physicochemical characteristics were similar to GM rice of vitamin A-enriched rice and a donor plant, Nagdong. However, grain appearance in GM rice of vitamin A-enriched rice showed to white core and white belly when GM rice of vitamin A-enriched rice was planted in greenhouse. The type and distribution of dominant weed species also were not different from GM rice of vitamin A-enriched rice and a donor plant, Nagdong. Additionally that of gene flow was not detected in dominant weed species by PCR analysis.
