ASHS 2015 Annual Conference

The purpose of this study was to assess the growth characteristic, yield and functional properties Peruvian origin quinoa (Chenopodium quinoa Willd.) 24 strains by different cultivation areas in South Korea. Collected quinoa lines were grown in three growing areas (Gangneung, jinbu, Dargwallyeong). These areas are 40meters, 600meters, and 800meters above sea level and sowed mid. April, late April and mid. May respectively Gangneung, Jinbu and Daegwallyeong in 2013 and 2014. Days of growing season from seeding to heading stage were 14~39 days in Gangneung, 34~45 days in Jinbu and 52~73 days in Daegwallyeong depending on the cultivars. Days of growing season from seeding to flowering stage were 26~85 days in Gangneung, 36~73 days in Jinbu, 110~120 days in Daegwallyeong. Plant height and stem width were the longest and thickest in cultivated in Gangneung and then Jinbu, Daegwallyeong. Yields were very low in Gangneung. System that can be harvested more than 1 ton per ha is Q24, Q28, Q30, Q31, Q34, Q40 were all six strains. Q34 strain showed best yield in Jinbu and Daegwallyeong. And this study was carried out in order to determine the functional properties such as total phenolic compound (TPC) and antioxidant activities in seven cultivars of Italian millet. Their antioxidant activities were measured using DPPH free radical scavenging activities. . The content of TPC was showed various values by strains. TPC value in the range 60~688mg/L, the highest value (688mg/L) was in Q22 strain. The free radical scavenging activity using DPPH method was highest in the Q22 (88%) strain as well. Antioxidant activities were shown different values by color of seeds. Seed color of Q22 and Q25 were gray-brown color
