Abstract

'Daejang 3ho' is a new cultivar of oyster mushroom for high productivity than that of Chunchu 2ho. This cultivar was bred by Di-mon mating between monokaryotic strains isolated from 'Daejang 1ho' and dikaryotic strain 'Jangan 5ho'. The color of pileus and the shape of pileus of new cultivar were dark gray and deeply funnel shape, respectively. The length and thickness of stipe were longer and thicker than those of Chunchu 2ho. It took 4~5 days to formation of primordia, that was a similar to Chunchu 2ho. The optical temperature of fruit body was $14-17^{\circ}C$. Yield of 'Daejang 3ho' was 13.9% higher than that of Chunchu 2ho. Analysis of RAPD by URP-primer of #03, #08, #10 and #11 showed that different band pattern those of other strains. There were no significant differences between the texture properties of 'Daejang 3ho' and Chunchu 2ho.

갓색이 진한 장안5호와 기존에 다포자임의교배법으로 육성된 대가 길고 두꺼운 특징을 가지는 대장1호를 Di-mon교잡하여 '대장3호'를 육성하였다. 갓색은 진회색이며 갓모양은 깊은깔때기형이다. 대길이와 대굵기는 각각 77.4 mm와 13.5 mm로 춘추2호보다 두껍고 길었다. 초발이는 4-5일로 춘추2호와 비슷하였으며, 생육온도는 $14-17^{\circ}C$로 조금 낮은 편이었다. 춘추2호와 비교하여 수량은 13.9% 높았다. 생육시 습도가 높으면 춘추2호와 '대장3호'는 대표면이 회백색을 띄기도 하였다. URP-primer를 사용하여 RAPD를 하였으며, URP primer #03, #08, #10, #11에서 '대장3호'와 모균주, 그리고 다른 교잡균주들과 동일하지 않음을 알 수 있었다. 대조직의 물리적 특성은 깨짐성과 응집성은 춘추2호보다 컸으며, 강도와 경도, 씹힘성은 춘추2호보다 낮았으나 통계적 유의성을 나타내지 않았다.
