초록

'용아'는 목이버섯 국내 수집 자원인 JNM21008과 JNM21013의 단포자 교배를 통해 2014년 전남농업기술원에서 육성한 품종이다. 2011년부터 2014년까지 자실체 특성 및 생산력 검정을 실시하였으며, 그 결과 2014년 갓 모양은 파도형으로 진한 흑갈색이며 연락맥은 갈회색을 띤 흑목이버섯을 최종 선발하였으며 2015년 품종보호출원, 2018년 품종보호등록하였다(제169호). '용아'의 재배적 특성과 수량성은 다음과 같다. 배양기간은 대조품종보다 더 빠르며 초발이 소요일수 또한 10일로 대조품종보다 5일 정도 빨랐다. 톱밥 봉지재배 시 자실체 특성으로 갓색은 대조품종보다 더 진한 흑갈색이었으며 유효경수는 13개/0.9 kg로 많았고 갓 장경 9.7 cm, 단경 5.6 cm로 갓 크기는 큰 경향이었다. 배양기간은 $20^{\circ}C$에서 약 40일이며 발이 및 생육기간은 24일로 기존 품종보다 더 짧은 편이며 수량은 0.9 kg 봉당 291 g이었다. 교배모본과 대치선이 형성되었으며 모균주와 구별성을 보였다.

'Yong-A' was bred by Jeollanamdo Agricultural Research and Extension Services in 2015. It was primarily selected through monospore crossing between JNM21008 and JNM21013 in 2009. The strain is named as JNM-Mi-194 and 'Yong-A', showing major characteristics with good production yield. The cultivation characteristics, yield potential, and fruiting body characteristics of 'Yong-A' are as follows; The wrinkle of the fruiting body was of branching type its shape was wave type. MCM, YM, Malt, and PDA media were suitable for growth of this cultivar. The number of effective stipes was 13 ea/0.9 kg. The minor axis of pileus was 5 cm and the major axis was 9 cm. The yield was 291 g per plastic bag (0.9 kg). Yong-A required 60 days for mycelial running at $20^{\circ}C$. The growth and primordial period required 24 days, which was shorter than that of JNM-Mi-21002 (the conventional cultivar). Somatic incompatibility was observed between parental lines and Yong-A. Analysis of genetic diversity in the new variety 'Yong-A' showed a different profile compared to that of the parent strain when Random Amplified Polymorphic DNA primers were used.
