신품종 ‘올찬메’는 충북 제천 재래 조를 수집하여 순계분리육종법을 통해 2022년 육성된 신품종으로 주요 특성은 이삭은 원통형으로 아래로 처지는 형태이고, 출수기는 표준품종인 ‘삼다메’에 비해 11일 정도 빠른 조생종 품종이다. 간장은 141 cm로 ‘삼다메’와 비슷하며 기계수확이 가능한 품종이다. 종실과 낟알은 황색이고, 조곡 천립중은 2.9 g이며 수량성은 평균 3.26 MT ha^-1로 나타났다. 재배 및 병해충 저항성에서는 도열병과 깜부기병 발생이 없었으며, 노균병은 낮은 수준으로 나타났다. 노린재 피해는 3 수준으로 신품종과 표준품종 간 차이가 없었다. 이화학적 성분으로는 조단백질 10.5%, 아밀로스 18.6%로 메조에 해당하고, 칼륨 및 마그네슘 함량이 ‘삼다메’보다 높게 나타났으며, 라디컬 소거능은 표준품종과 유사한 수준이었다. 종합해보면, ‘삼다메’에 비해 낟알 충실도가 높은 특성을 가진 신품종 ‘올찬메’는 제주 지역을 제외한 국내 전역에 걸쳐 광지역 적응성을 나타낼 것으로 전망된다.

Abstract

‘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.
