        At present, oak sawdust and rice bran are mainly used as the medium materials for bag cultivation of Lentinula edodes. This experiment was conducted to develop the optimum medium of ‘Nongjingo’, a new variety of Lentinula edodes. We investigated oak sawdust, oak fermented sawdust, poplar sawdust, and douglas fir sawdust as main materials, and rice bran and wheat bran as nutrient resources, respectively. The medium composition was consisted of main material 80%+nutrient 20% based on the volume ratio. Eight treatments of medium composition were tested. The period of mycelial incubation in ‘oak sawdust 40%+douglas fir sawdust 40%+rice bran 20% was 86 days (39 days in dark incubation and 47 days in browning) shortened up to 18 days compared to the control. The 1st yield of commercial fruiting bodies in this treatment was 48.1 g/bag which was 44.8% higher than that in control. We expect that the cultivation period of ‘Nongjingo’ will be shortened, and the yield increased in the medium replaced half of oak sawdust by douglas fir sawdust.

        ‘Baekseung’, a new variety of Flammulina velutipes, was bred by mating two monokaryotic strains isolated from KMCC 4210 and KMCC 4216 in Mushroom Research Division, Baekseung ARES in 2016. Baekseung showed fast mycelial growth and high mycelial density on MEA (Malt Extract Agar) media for 7days of incubation. Spawn running period on the sawdust substrate required 30days at 25°C. The cultivation period and optimum temperature were 11±1 days at 14°C for primordia formation and 14±1 days at 7°C for fruiting body development. The length of pilei and stipes in Baekseung harvested in optimal stage exhibited 11.3±0.4㎜ and 89.2±7.1㎜ and Megumi harvested in optimal stage showed 8.2±1.0㎜ and 95.9±5.0㎜ respectively. Yield of Baekseung and Megumi strain grown of sawdust substrate was 153.7±12.5g and 150.5±29.7g per 850ml in bottle cultivation. The inferred tree exhibited the difference of phylogenetic relationship between the Korean white fruiting body strains such as Baekseung, Uri1ho, Fv-14-a-38, and Fv-14-a-51 and the Japanese white fruiting body strain Megumi.

        In this study, we investigated the amino acids content of shiitake mushrooms grown in eight different media and under three different temperature conditions. The sawdust media were supplemented with 4 kinds of nutrients - rice bran, barley, bean curd refuse, and red ginseng refuse in an 8:2 ratio with or without 0.5% calcium chloride, and the fruiting temperature was set to low (13–15oC), medium (18–20oC), or high temperatures (24–26oC). Seventeen amino acids were detected, and the content varied depending on the compositions of the media. The highest total amino acid content (209.7 mg/g) was measured in mushrooms from the media with red ginseng refuse, and the glutamic acid content was the highest (51.3 mg/g) in mushrooms from the media with barley. In terms of fruiting temperature, the amino acid content was the highest (38.2%) at medium temperature followed by the content at low (32.5%) and high temperature (29.3%). The amino acid composition of shiitake mushrooms was similar between the medium and low temperature conditions.

        The purpose of development new variety ‘Miho’ (Hordeum vulgare L.) is a favorite with livestock feed and develop varieties resistant to disease and lodging. ‘Miho’ was carrying out the growth habit of group Ⅲ with green and mid-wide leaf. Awn that is related to preference of livestock is a semi-smooth awn. This cultivar had 96 cm of culm length, 650 of spikes per m2. Heading date of ‘Miho’ was April 27, and maturing date on May 30, which were later than cultivar ‘Youngyang’. It also showed strong winter hardiness, and similar resistance to shattering and bariy yellow mosaic virus (BaYMV) compared with those of check one. The best thing among the traits of a good quality with the plant green at the latter growing period. The average forage dry matter yield in the regional yield trial was about 13.1, 12.1 MT per ha in upland and paddy field, respectively, which were 9%, 2% higher than that of the check cultivar. It’s also showed 6.8% crude protein, 27.1% ADF (acid detergent fiber), and 67.5% TDN (total digestible nutrients), including higher silage quality for whole crop barley. This cultivar would be suitable for the area whose average minimum temperature was above -8℃ January in Korean peninsula.

        Geoni, a new variety of Auricularia polytricha, was bred in JARES(Jeollanamdo Agricultural Research and Extension Services) in 2012. Geoni was selected through the monospore hybridization with JNM21008 and JNM21014 in 2010. Based on a performance test conducted from 2011 to 2012, the Geoni was selected from a line showing an excellent light brown pileus and strong pest resistance. Geoni has a favorable chewiness, light brown and smooth pileus. In addition, Geoni was rich in dietary fiber. MCM(mushroom complete medium), Malt and PDA(Potato Dextrose Agar) mediums were suitable for cultivating the Geoni. The number of effective stipes was 39 ea/0.9 kg and minor axis and major axis of pileus were 6.9 cm and 8.7 cm respectively. The yield of Geoni was 291 g/0.9 kg in plastic bag. Geoni was required 40~54 days for culture at 20oC and 24days for the primordia and growth period, which is longer than that of the control(Pung-un). Somatic incompatibility was formed between parental strains and Geoni. Analysis of the genetic diversity of the new variety "Geoni”revealed a different profile from the parental strains when RAPD(random Amplified Polymorphic DNA) primers were used.

        ‘Mantari’ is a new variety of oyster mushroom for bottle culture. It was bred by crossingmonokaryons isolated from ‘DM11732’ and ‘Chunchu-2ho’. The optimum temperature for the mycelial growth was 26~29°C on PDA medium, and that for the primordia formation and the growth of fruiting body of ‘Mantari’ on sawdust mediawas 18°C and 16°C. It took 32 days to finish spawn running, 4 days to finish primordia formation, and 3 days to finish fruiting body growth in the bottle culture. The fruitcharacteristics: the pileus was round and gray-black in color, and the stipe was long, thin, and light gray in color. The yield per bottle was 179 g/900 ml and was 5% higher than that of the control variety (Chunchu-2ho). The physical properties of the fruit body were as follows: springiness, cohesive, gumminess, and brittleness of the stipe tissue were 96%, 76%, 160 g, and 15 kg, respectively.

        Since the first Korean button mushroom ‘Sae-Ah’ developed in 2010, most farmers had wanted to cultivate a new variety. A new variety, ‘SaeJeong’, was developed in 2011, but this variety was difficult to cultivate in mushroom farm. To solve the variety problem, a new variety ‘Sae-do’ was developed in 2012. The variety, ‘Sad-do’, was made by crossing hetrokaryon A175 and homokaryon ASI1346-15 selected by genetic analysis. The heterokaryon A175 is crossed line between ASI1038-211 and ASI1346-20. The mycelium of ‘Saedo’ on CDA (compost dextrose agar) grew well at 25°C. The optimum pin-heading temperature of it was 13-15°C and optimum growing temperature was 13-20°C. Earliness (days required from casing to first harvesting) was 2 days shorter than control ‘Saejeong’. Even though the diameter of mature cap and the length of stipe were shorter than a control, the individual weight of fruiting body was heavier because of thick pileus and stipe. Therefore, the yield was increased by 1.89 times than control and the hardness of pileus was stronger. The field experiment of ‘Saedo’ variety has been started since 2013. Most farmers evaluated that the variety has good compost colonization and cap shape, and high yield in harvesting. For that reason, ‘Saedo’ has occupied half of the of distribution rate of Korean varieties. Also distribution rate of Korean varieties was increased from 26.1% in 2014 to 37% in 2015.

        느타리버섯(Pleurotus ostreatus)의 품종 육성을 위해서는 많은 노력과 시간을 필요로 하고 있어, 최근에는 분자육종방법으로 마커를 이용하여 빠르고 정확하게 교잡주를 선발하고 있다. 본 실험에서는 육종효율을 증진하기 위해 교잡효율이 높은 Di-Mon 교배방법으로 부친의 핵과 모친의 미토콘드리아를 가진 세포질전환 교잡주를 선발하였다. 느타리버섯 수한3호와 흑변이체의 교잡종인 ‘다굴’의 이핵균주에 춘추2호의 단핵균주와 교잡하여 120여개의 교잡주를 얻고 여기에 1차로 미토콘드리아 microsatellite DNA 마커 (MtPO1)를 이용하여 단핵균주 춘추2호의 미토콘드리아 밴드를 형성하는 교잡주 80개를 1차 선발하였다. 선발된 80균주중에서 URP 프라이머를 이용하여 ‘다굴’의 2핵균주 핵 DNA 패턴을 가진 26교잡주를 선발하였다. 이 중에서 수량성이 우수한 3개 교잡주의 자실체 특성을 조사한 결과 초발이일수가 2일이나 빠르면서 수량성이 좋은 품종을 선발하여 ‘천화심’이라 명명하였다. 천화심은 수량이 높으면서 여름에도 재배가 가능해 춘추2호의 약점을 보완함으로써 춘추대체품종으로도 재배가 가능하리라 본다.
