‘Olchanme’ is a new foxtail millet variety developed by Chungcheongbukdo Agricultural Research & Extension Service from 2011 to 2021. This variety was collected in Jecheon and developed through pure-line selection. The culm length of ‘Olchanme’ is similar to that of the standard variety ‘Samdame,’ but its panicle length is longer. The panicle shape differs between ‘Olchanme’ and ‘Samdame,’ but other inherent characteristics (panicle type, grain color, dehusked grain color, and endosperm) are similar. The grain and dehusked grain colors were yellow, and the endosperm was non-glutinous. The heading period is 11 days earlier than that of ‘Samdame,’ indicating that ‘Olchanme’ is an early-maturing cultivar. In local adaptability tests, conducted from 2018 to 2021, excluding 2020, the average grain yield of ‘Olchanme’ is 3.26 MT ha-1. In terms of physicochemical composition, the crude protein content was 10.5% and amylose content was 18.6%, classifying it as a non-glutinous type. Its potassium and magnesium contents were higher than those of ‘Samdame,’ while radical scavenging activity was similar to that of the standard variety. Overall, the new variety ‘Olchanme,’ characterized by higher grain filling than ‘Samdame,’ is expected to demonstrate wide regional adaptability across the entire country, excluding Jeju Island.
