Background : The Schizonepeta which is characterized by short growth period is used for the pedicel as a medicinal plant. Its main ingredients are essential oil, monoterpenoid, and flavonoid. Major effects include fever, pain, anti-inflammation, and anti-allergy. There are no varieties developed so far, and it is necessary to develop standard varieties to supply domestically good varieties. In this study, the growth and yield characteristics of the genetic resources collected for cultivating good-quality varieties were tested. Three strains were classified into early, medium, and late life.
Methods and Results : The research was carried out in the test packaging of the Medicinal Resources Research Institute (Hamyang) in Gyeongnam province. It was harvested in late May, early June, and mid June by flowering season. The harvest time was mid June, late June, mid July, late July, mid August, and late August. Flowering, growth characteristics and yield were investigated. Growth characteristics showed a tendency to increase with the delay of flowering and harvesting time, such as plant height, leaf length etc. As the flowering time and harvesting time were delayed, the number of trees increased. The selected early line showed 89.4 ㎝ in plant length, 38.3 g grain weight, medium line 69.5 ㎝, 61.0 g, late line 136.4 ㎝, 111.2 g.
Conclusion : When the cultivars are selected for the selected strains, it is expected that the cultivars with high physiological activity characteristics will be able to develop the cultivars as high quality varieties and high yield varieties.
