영문 초록

‘Tocomi-1’, a rice variety with high tocopherol content and a reddish brown color was developed from ‘Dongan’ by a mutation breeding technique using a 120 Gy gamma ray source at the Korea Atomic Energy Research Institute (KAERI). The heading date of this variety was August 12, which was 2 days later than the original variety ‘Dongan’. The culm and panicle lengths of ‘Tocomi-1’ were 80 cm and 20.3 cm, respectively. The number of tillers per hill was 19.1 and the number of spikelets per panicle was 106.3. The ratio of ripened grain was approximately 87.0% and the weight of 1000 grains was 25.4 g. The pericarp of brown rice was reddish brown in color. The total tocopherol content was 1.65 mg/100g, which was higher than that of the original variety (1.09 mg/100g). In addition, the brown rice of ‘Tocomi-1’ contained 8% more total amino acids. The average yield potential of ‘Tocomi-1’ in grain and brown rice was approximately 6.18 kg/10a and 5.15 kg/10a for 3 years, respectively (Registration No. of Plant Protection Wright : 6813).
