Abstract

Since the discovery of the pure culture methode of shiitake mushroom spawn, the production of shiitake mushroom has steadily increased. More than 260 cultivars (varieties) among the spawns on the market were analysed by the Forestry Agency and the numbers of reported spawn makers amounted to 126 in 1983. This study intended to analyse the relation between the degree of the necessity of the choice and the criteria of the choice for shiitake mushroom cultivators. The result indicated mushroom cultivator's characteristic process of the choice of variety. "As the important purpose of the improvement of variety was generally to increase the adaptability to natural phenomena, the natural condition played an important role for the crop caltivators to decide their varieties. But for the mushroom cultivators, owing to spawn makers' great efforts for its improvement, the process of their choice was different from the other crops cultivators.
