Abstract

Two strains Pleurotus eryngii 'Aeryni' and 'Na' carrying superior traits of a pileus and a earliness of harvest were selected to improve previously bred strains by single crosses. New hybrid, Aeryni 3 (Aeryni10 ${\times}$ Na5) showed superiority to other hybrids in yield, fruit body shape and days for harvest. The new strain, Aeryni 3 was harvested earlier than Keunneutari No. 2 by 2~3 days, and yielded 110.5 g/bottle (850 mL) which was 108% of that of Keunneutari No. 2. The ratio of diameter of pileus and stipe was 1.8 indicating that new stain will be likely low damage rate of fruit body during a distribution, and that was better than 2.1 of Keunneutari No. 2. A sensory test of taste of the new strain showed that 84.7% of evaluation panels selected "very good" while that of Keunneutari No. 2 was 55.5%. In purchasing intent test, 86.9% of panels will buy the new stain whereas 46.8% will buy Keunneutari No. 2 implicating that the new strain will likely be more marketability than previously bred strain.

기존 큰느타리버섯 품종의 단점을 개선하고자 단교배를 통하여 여러 가지 형질을 복합적으로 지니는 품종을 육성하고자 애린이와 나 계통을 모본으로 선택하고, 이들 계통으로부터 유래한 단핵균사간의 단교잡을 실시하였다. 애린이10${\times}$나5계통이 수확량, 생육소요일수, 전체적인 모양에서 다른 계통보다 우수하였고 이 계통을 애린이 3으로 명명하였다. 애린이 3은 큰느타리2호보다 수확일이 2~3일 빠르고, 수확량도 110.5 g으로 기존품종의 108%수준이었다. 갓직경과 대두께의 비율은 1.8로 기존품종의 2.1보다 우수하여 수확이나 유통시 버섯의 손상이 적을 것으로 사료된다. 소비자에 대한 맛과 구매의향 조사에서 육성계통은 31.4%가 매우우수, 53.3%가 우수로 평가한 반면 기존 품종은 20.7%가 매우우수, 34.8%가 우수로 판정하였다. 구매의향도 총 86.9%가 높음 이상이어서 기존 품종의 46.8%보다 높아 시장성이 높을 것으로 사료된다.
