본 시험 결과를 요약하면 다음과 같다. 1. 공시교잡종의 평균 과피두께는 $37{mu}m$로 얇은 특성을 보였는데 특히 CNU108 교잡종이 $30.3{mu}m$로 가장 얇은 특성을 보였고 출사일수는 CNU69와 CNU202 등이 59일로 가장 빨랐으나 CNU160 교잡종은 68일로 본 교잡종들 중에서 가장 늦었다. 2. CNU70과 CNU138의 교잡종들은 높은 항산화효소(xanthin oxidase, catalase, superoxide dismutase)의 활성을 나타내었고, 특히 CNU160과 CNU193 교잡종은 각각 94.8%, 94.6% 등으로 높은 항산화력(EDA)을 나타내었다. 3. CNU109와 CNU34의 교잡종에서는 전반적으로 높은 항산화효소 활성 및 항산화력을 나타내었다. 따라서 CNU34, CNU70, CNU108, CNU138, CNU193 등의 교잡종 찰옥수수가 항산화 효과가 높은 고기능성 유색 찰옥수수인 것으로 사료되었다.
This study was carried out to evaluate major agronomical characterization and phenol compound contents, Xanthine oxidase inhibitory activity (XO), Catalase activity, Superoxide dismutase activity (SOD) and 1,1-Diphenyl-2-picryl-hydrazyl (DPPH) radical sacvenging activity were analyzed in colored waxy corns. The mean of stem height and ear length were 248.8 cm and 18.6 cm, respectively. The pericarp thickness in CNU108 $(30.3{mu}m)$ was thinner than other hybrids. The period of tasseling days in CNU69 and CNU202 were very shorter than other hybrids (59 days). 100-kernel weight of CNU50 was 35.6 g and heavier than the others. The antioxidant activities such as xanthin oxidase (XO), catalase and superoxide dismutase (SOD) were higher in CNU70 and CNUI 38. Especially highest EDA (electron donating ability) in DPPH radical scavenging effect was 94.8% and 94.6% in CNU160 and CNU193, respectively. In the results, the antioxidant enzyme activity and antioxidant acticity were higher in CNU109 and CNU 34 hybrids. The hybrids, CNU34, CNU70, CNU108, CNU 138 and CNU193 may be considered higher functional color waxy corn.
