Abstract
This study was carried out to develop the utilization of mulberry resources conserved by Jeollabuk-Do Agricultural Research & Extension Services. Mulberry accessions were tested for agronomic characteristics and antioxidant capacity according to varieties. From that result, three suitable varieties such as 'Sinilppong', 'Suwonsang 2' and 'Ilbongeum' were selected for the production of mulberry leaves. They have strong agronomic characteristics like size, yield and resistance against damages by blight and harmful insects. Whereas, 'Gumunyoung' showed the lowest freezing resistance. In the antioxidant capacity analysis of mulberry leaves, autumn's mulberry leaves showed higher antioxidant capacity (ascorbic acid equivalent) than that of spring's it. According to collection time, antioxidant capacity were 2,109.8 nmol (August), 2,617.8 nmol (September) and 3,311.5 nmol (October), respectively.
