Anthocyanin, a group of purple or reddish flavonoids, have been recognized as health-promoting functional food ingredients due to antioxidant activity. For this reason, plant breeders are trying to increase the anthocyanin contents using methods such as classical breeding and biotechnological approaches. To broaden the mutants population, seeds of colored wheat variety (K4191) were irradiated by using 250 Gy gamma irradiation. Individual 968 M4 plants were grown in Korea Atomic Energy Research Institute field. Many mutant phenotypes were shown: seed color variation, abnormal spike shape, awning formation, heading and ripening time, plant height, ripening period, super dwarf, etc. To identify the inheritance traits of colored-wheat, individual lines were maintained the spike base classified by generation. Characteristics per spike and plant were piled up to construct for mutant database. In the future, fixed descent will be analyzed the anthocyanin contents or other phytonutrients by ultra-performance liquid chromatography (UPLC). Expression of seed color-related transcription factors and anthocyanin biosynthetic pathway genes will be examined.
