This study was carried out to develop the new colored waxy corn hybrids with high yield and functional characteristics using the domestic collected genetic resources. Botanical characteristics and antioxidant activities of the developed CNU (Chungnam National University) waxy corn hybrids were analyzed and evaluated for selection of superior hybrids with high yield including high table quality. Stem height of CNUl9 hybrid among developed hybrids were higher as 242 cm and its ear height were also higher as 52 cm than check, Chalok 1. Tiller per plant of CNU19 was high as l.5 compared to 0.8 of check Days to tasseling appeared as 74 days and ear length of CNU19 were longer than check, Chalok 1. Lodging and insect resistance of CNU19 was 2 and 3, respectively, stronger than other hybrids. Pericarp thickness of CNU19 in yellow waxy hybrids was thinner than 40 micro m which was a selection criterion of edible waxy corn hybrid. Sugar content (Brix) of the developed CNU19 waxy corn hybrid was comparatively lower than check. In table quality, CNU12 and CNU19 hybrids were good than check in sugar content and tenderness. In functional analysis, 1,1- diphenyl-2-picryhydrazyl (DPPH) radical scavenging effect, xanthine oxidase (XO) activity and catalase activity by methanol extracts were comparatively appeared high in CNU19. CNU19 and CNU 153 hybrids from ethanol extracts showed also higher antioxidant activities.
