Background: Astragalus membranaceus belonging to the Leguminosae family is often utilized as a traditional medicine. The aim of this study was to elucidate the basic breeding information required to develop short stem A. membranaceus cultivars.
Methods and Results: Roots of A. membranaceus advanced yield trial (AYT) lines were harvested in late October 2017. Root yield of six AYT lines were increased in a range of 8.9 - 74.8% compared with ‘Aseong’ as control (check variety). The height of seven AYT lines were shorter than that of ‘Aseong’. In addition, stem diameter of nine AYT lines was thicker than that of ‘Aseong’. Consequently, 1502-56, 1503-90, and 1510-80 were selected as elite lines for the development of short stem cultivars. HPLC analysis was perfromed to identify lines with high level active components such as calycosin-7-O-β-D-glucoside and calycosin. The levels of both active components were higher in 1502-56, and 1503-90, but not in 1510-80 compared to ‘Aseong’. In addition, 2,2-Diphenyl-1-picryl hydrazyl (DPPH) radical scavenging activity was higher in the 1502-56 compared to ‘Aseong’. Considering these results, two AYT lines, 1502-56 and 1503-90 were selected as short stem lines with high calycosin-7-O-β-D-glucoside and calycosin content.
Conclusions: Taken together, Two short stem lines were identified in this study. In our future study, regional yield trial (RYT) will be conducted using these selected lines to develop new cultivars.
