Background : Astragalus membranaceus belonging to the family of Leguminosae have been utilized as a traditional medicine. The aim of this study is to elucidate the basic information for breeding to superior Astragalus membranaceus cultivar.
Methods and Results : Selection lines were developed by the medicinal crop breeding team of National Institute of Horticulture and Herbal Science (NIHHS), Rural Development Administration (RDA). The root of A. membranaceus lines were harvested in late October 2017. Calycosin-7-O-β-d-glucoside and calycosin were anlyzed by HPLC. The root yield of six selection lines were increased 8.9 - 74.8% compared with ‘Aseong’ (check variety). Also, the plant height of seven selection lines were shorter than ‘Aseong’. The calycosin–7-O-β -d-glucoside content was higher in six selection lines than ‘Aseong’. The calycosin content was higher in all selection lines except 1 line (1508 - 03) than that of ‘Aseong’.
Conclusion : Three superior lines with short height and high yield were selected. These superior lines will conduct advanced yield trial to make varieties.
