This study was conducted to investigate the physiological activities and nutrition contents of Gonji No.10 and Solhyang, the strains of Neolentinus lepideus. In nutritional contents of two strains of N. lepideus, the content of free sugars and sugar alcohols and total polyphenol were more in Gonji No.10 than Solhyang. The total contents of amino acids and ${\beta}$-glucan in Solhyang are more than those in Gonji No.10. Solhyang also showed higher DPPH radical scavenging activity than Gonji No.10. In particular, hot water extract of Solhyang has higher inhibitory activity of ${\alpha}$-amylase and ${\alpha}$-amyloglucosidase while Gonji No.10 has higher anti-inflammatiory effect than Solhyang. But, they have similar effects on nitrite scavenging activity.

We aimed to develop a new variety of Neolentinus lepideus from about forty strains by bag culture. To this end, "Solhyang" which means pine smell in Korean was selected as a new commercial variety of N. lepideus. N. lepideus have yellow pileus and pine smell, which characteristics make a favorable impression on the far east Asia, Korean and Japanese. The optimum temperatures for mycelial growth and fruit body development ranged $26{\sim}32^{\circ}C$ and $18{\sim}20^{\circ}C$, respectively. The required periods of mycelial incubation and fruit body growth were 30 days and 7 days, respectively. The fresh weight of fruit body was 115g/kg with pine sawdust and corn meal power(9:1, v/v) substrate.

'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.
