Abstract

Phylogenic relationships and morphological characteristics were classified and investigated among the 233 collected strains of Agaricus spp. The 38 strains were differently identified as different characteristic group using analysis of ITS regions in rDNA. A. bitorquis was showed close relationship in groupA whereas A. campestris was in groupC as different characteristic group among with A. bisporus. There was no phylogentic difference with strains collected by country and different pileus colored Agaricus bisporus. Also the strains were cultivated twice to investigate morphological characteristics of fruiting bodies. The characteristics and yield of collected strains were compared with molecular varieties and seasons by the cultivation. In this result, A. campestirs showed good yield and quality in terms of hardness off-white mushroom was more harder than other number of A. bisporus. Also earliness and color of pileus was influenced by external environment all conditions.

수집된 주름버섯류의 233점의 phylogenic relationship을 분류하고 자실체형태를 조사하였다. 리보좀 DNA의 ITS 부분의 염기서열을 분석을 통해 38점이 다르게 동정되었다. 수집된 주름버섯의 계통수에서는 양송이와 여름 양송이가 group A 내에서 주름버섯은 group B에서 가까운 유연관계를 보였다. 또한 수집된 국가별 및 양송이내 갓색에 따른 유연관계가 있는 지 알아보았으나, 그 차이는 없었다. 수집된 주름버섯류의 자실체 특성을 조사하기 위해 1차, 2차 두 번 재배를 하였다. 이 결과로 주름버섯류 수집균주의 재배의 유무를 알 수 있었고, 버섯 종류와 시기에 따른 수확량 및 자실체의 특성을 비교를 통해 주름버섯이 2차 재배시 수확량 및 경도에서 우수한 특성을 보이며, 양송이 중에는 비백색양송이가 단단하다는 것을 알 수 있었다. 또한, 여름양송이의 초발이 소요일수와 갈색양송이의 갓 색이 외부환경에 영향을 받는 다는 것을 보여주었다.
