        This study compared the quality and drying characteristics of dried king oyster mushroom (Pleurotus eryngii), shiitake mushroom (Lentinus edodes GNA01) and maitake mushroom (Grifola frondosa) slices obtained by sundrying, hot-air drying (40, 50, 60 ), low-temperature vacuum drying (20, 25, 30 ), heat-pump dehumidifying drying (30, 40, 50 ), and freeze drying. The quality changes investigted included color, browning degree, hardness, general components, -glucan. Color changes in king oyster mushroom during freeze drying were β less than that between control (raw) and treated mushrooms. Compared with other drying methods, low-temperature vacuum drying of shiitake mushroom resulted in less color changes. Browning degree differed significantly between the different drying methods. As temperature increased, low-temperature vacuum drying resulted in decreased browning while heat-pump dehumidifying drying resulted in increased browning. In king oyster mushroom, hardness increased with temperature under hot-air drying, low-temperature vacuum drying and heat-pump dehumidifying drying. In shiitake mushroom, hardness increased with increasing temperature under hot-air drying and heat-pump dehumidifying drying. β-glucan content after drying was found to be between 28.29 and 39.39% in king oyster mushroom, 23.05 and 29.48% in shiitake mushroom and 16.10 and 24.51% in maitake mushroom.

        This study was carried out to analyze correlation between heterosis of F1 hybrids and the genetic distance of parental lines. Growth characteristics such as number of leaves, plant height, bulb diameter, bulb height, bolting rate and marketable yield were examined in 15 F1 hybrids. The genetic distance among one male sterile line and fifteen restorer lines were analyzed with SSR markers. 21 primer pairs amplified polymorphic band and the average number of polymorphic allele was 3.4. As a result of UPGMA cluster analysis, the similarity coefficient value among parental lines ranged from 0.43 to 0.63. Combination of M1 and R14 is high similarity and number of leaves, plant height and yield are 10.2, 66.7cm and 6,818kg·10a-1. The case of the lowest value combination, they are 9.0 and 63.7cm and 7,728kg·10a-1, respectively. The results showed that there are no significant correlations between genetic distance and heterosis of F1 hybrids and only molecular marker does not predict growth traits and yield of onion.
