Abstract
'Gonji10ho', a new variety of Neolentinus lepideus, was bred by mating two monokaryotic strains isolated from 'GMNL66037' and 'GMNL66014' in Mushroom Research Institute, Gyonggi-Do ARES in 2012. The optimum temperature for the mycelial growth of 'Gonji10ho' was $29^{\circ}C$ on PDA medium and that for the primordia formation and the growth of fruiting body of 'Gonji10ho' was $20{\pm}1^{\circ}C$. In bottle cultivation of 'Gonji10ho', the period of spawn running was around 35 days at $22{\pm}1^{\circ}C$ and the period from scratching of inoculum to harvesting was 27 days. 'Gonji10ho' had thicker pileus and stipe than control variety('Solhyang'). The number of available stipe was fewer than that of control variety. During the cultivation of 'Conji10ho', the occurrence rate of Trichoderma spp. was lower than that in control variety. In bottle cultivation, the yield of fruiting bodies of 'Gonji10ho', which was 38% higher than that of control variety, was 69.6 g/900 ml bottle, and in bag cultivation, that of 'Gonji10ho', which was 10% higher than that of control variety, was 114.2 g/1 kg bag. In physical characteristics, the strongness and brittleness of the pileus of 'Gonji10ho' were higher than those of control variety. When considered in the period available for sale, the shelf life of 'Gonji10ho', which was 5 days longer than that of control variety, was 34 days.
잣버섯의 다수성 신품종 개발을 위하여, 단포자교잡에 의해 육성된 신품종 '곤지10호'의 주요 특성은 다음과 같다. 균사생장적온은 $29^{\circ}C$, 버섯 발생 및 생육온도는 $20{\pm}1^{\circ}C$로 대조품종과 같았으며, 균사 활력도 대조품종과 비슷하였다. 갓형태는 반반구형이며, Hunter 색체값으로 볼 때 갓색은 L 79.3, b 24.8, 대색은 L 84.3, b 10.9로, 갓색에 있어서 대조품종에 비하여 황색도가 더 높았다. 미송톱밥+옥분(90:10, v/v)배지로 병재배 시 배양일수는 $22{\pm}1^{\circ}C$에서 35일, 발이일수와 자실체생육일수는 $20{\pm}1^{\circ}C$에서 15일과 12일로 재배일수는 62일이 되어 대조품종보다 2일 길었다. 자실체 생육 특성은 대조품종에 비하여 갓두께는 6.3 mm로 두꺼웠으며, 유효경수는 3.5개로 적었고 대 직경은 21.6 mm로 굵었다. 재배접종 후 배양 및 생육 중 푸른곰팡이병(Trichoderma spp.) 발생율은 4.9%로 대조품종보다 낮았다. 수량은 생산력 검정 결과 병재배 시 900 ml병당 69.6 g, 봉지재배 시 1 kg봉지당 114.2 g으로 대조품종 대비 38%와 10%씩 많았다. 자실체 물리성에서 갓의 강도와 취성이 대조품종보다 강했고, 저장성은 판매가능기간으로 볼 때 34일로 대조품종에 비하여 5일 길었다.
