To develop mushroom varieties for cultivating at low temperature on oak logs, a strain with a low fruiting body generation temperature was crossed with Di-mon to select for a line with excellent properties. Selection was followed by cultivation testing. From these studies, Heunghwa 1ho was identified. The optimum temperature for cultivating Heunghwa 1ho, was 13.3℃. The fruiting temperature range was 6.4~20.2℃, identical to that of the parent strain. Growth at 25℃ for 7 days achieved optimal mycelial growth of 61.9±2.10 mm, superior to growth of the parent strain at this temperature. The cap shape of Heunghwa 1ho was convex, cap diameter was 57.8±8.31 mm, and cap color was brown. Heunghwa 1ho showed similar genetic traits to those of the parental strain. However, dry weight (20.1 kg/m3) and cap diameter and color are superior to those of the parent strain. The 3 year fresh oak mushroom yield was 113.8 kg/m3, superior to the respective yields of the parent strains JMI 10047 and JMI 90021 (92.5 kg/m3 and 66.4 kg/m3). 표고 원목재배용 중저온성 품종을 육성하기 위해 자실체 발생온도가 낮은 모본균주를 Di-mon 교배한 후 실증시험에서 우수 계통을 최종 선발하여 '흥화1호'를 품종보호출원하였다. '흥화1호'의 버섯 발생온도는 13.3℃이며, 발생온도 범위는 6.4~20.2℃로 모본균주와 같은 중저온성 품종으로 확인되었다. 또한 최적 균사 생장온도는 25℃에서 61.9±2.10 mm를 생장해 모본균주보다 우수한 생장력을 보였다. '흥화1호'의 자실체 형태는 모본균주의 특성이 많이 유전되어 형태적으로는 유사한 경향을 보였지만, 갓 직경(57.8±8.31 mm)과 색깔(brown), 건조중(20.1 kg/m3)은 모본균주보다 더욱 향상되어 나타났다. 3년간의 생표고 생산성은 '흥화1호'가 113.8 kg/m3를 생산해 모본균주인 JMI 10047과 JMI 90021의 92.5 kg/m3, 66.4 kg/m3 보다 높게 나타났다. 또한 버섯 발생형은 봄·가을 집중발생형으로 나타났다.
