　A new gerbera variety ‘Yellow Wing’ was released by the National Horticultural Research Institute (NHRI) in 2007. A cross was made between ‘Gold Finger’ with yellow and single and ‘Yellow Springs’ with yellow and spider in 2004. After investigation of the characteristics for 4 years (from 2004 to 2007), it was selected specially for the use of cut-flower. ‘Yellow Wing’ is a vigorous cultivar with yellow (RHS YO14B), green center and spider type. The flower diameter is 10.6cm. And inner ray floret and disc diameter is 2.83cm and 2.03cm, respectively. It produces a large yield with continuous supply of flowers and has adequate peduncle height and brilliant color. We believe that ‘Yellow Wing’ has a great potential for expanding cultivated area of domestic gerbera cultivar and increasing farmers-income.

　A new naked oat cultivar ‘hoyang’(Avena sativa L.) was developed by the breeding team at the Department of Rice and Winter Cereal Crop, NICS, RDA in 2007. It was derived from a cross between ‘ikyonggwiri’and ‘wiri23’ The cultivar, Sikyonggwiri is early heading while the breeding line Gwiri23 has a high yielding potential with large-size grain. Bulk method combined with pedigree selection program was employed in subsequent generations, and the promising line SO96025-B-303- 44-2-5 was selected for agronomic performance in 2002. The line showed both high yield and good husking rate of seed in the Yield Trial tested at Suwon in 2003 to 2004, and was subsequently designated as ‘wiri57’ Gwiri57 was evaluated for winter hardiness, earliness, and yield in four locations, Gimje, Iksan, Jeongeup and Jinju from 2005 to 2007 and was released as Choyang. Choyang headed 11 days earlier and matured 5 days earlier than the check cultivar ‘unyang’in the paddy field condition. The new cultivar Choyang had 97 cm of culm length and 23.4 cm of spike length, 658 spikes per m2, 75 grains per spike, 28.8 g of 1,000-grain weight, and 636 g of test weight. Choyang showed better winter hardiness than that of the check cultivar Sunyang, and similar seed quality to the check cultivar in respect to crude protein (12.9%) and β-glucan content (4.7%). However, it showed higher husking rate than the check cultivar. The grain yield of Choyang in the regional yield trial for 3 consecutive years was averaged 4.67 MT ha-1, which was 38% higher than that of the check cultivar Sunyang. Choyang is recommended for the fall sowing cropping only in the southern area where daily minimum mean temperatures are averaged higher than -4℃ in January, and is not recommended the in mountain area where frost damage is presumable.

A new whole crop silage barley cultivar, “oungyang” was developed from the cross between “unong and Milyang55 at the Yeongnam Agricultural Research Institute (YARI) in 2002. An elite line, YB3882-3B-17-1-3-1, was selected in 1999 and designated as “ilyang111” It showed good agronomic performance in the regional adaptation yield trials (RYT) from 2000 to 2002 and was released by the name of “oungyang”with higher yield and better animal feed quality than that of Olbori. The average heading and maturing dates of Youngyang were May 2 and June 6, which were late by 2 & 1 days than those of Olbori, respectively, in Suwon. Youngyang had longer culm length, 83cm but it had lesser spikes per m2 637 than that of Olbori, respectively, in RYT from 2000 to 2002. The rate of leaf sheath/whole length (culm+leaf) and the rate of the grains/ whole crop weight was similar to Olbori. It showed resistance to BaYMV at the regions of Naju, Jinju, Milyang andt Iksan. however, the response of Youngyang to other environmental stresses (tolerance of cold and wet) was similar to Olbori. The dried whole crop yield potential of Youngyang in the RYT was about 11.67 MT/ha in paddy fields which was about 18% higher than that of Olbori. The grain yield potential was 6.32 MT/ha in paddy fields which was about 5% higher than that of Olbori. Youngyang had lower rate of shattering, higher content of protein and NDF, lower ADF and TDN, and better quality of silage than those of Olbori.

　A new sprout-soybean cultivar, “oseo”was developed at the Honam Agricultural Research Institute (HARI) in 2007. Hoseo was selected from a cross between Camp and Nattosan. The preliminary, advanced, and regional yield trials to evaluate the performance of Iksan 57 were carried out from 2003 to 2007. This cultivar has a determinate growth habit with purple flower, grayish brown pubescence, yellow seed coat, grayish brown hilum, rhomboid leaflet shape and small seed size (7.4 g/100 seeds). The maturity date of “oseo”is 12 days earlier than the check variety, “ungsan” It has good seed quality for soybean-sprout and resistance to lodging. This cultivar has resistance to soybean mosaic virus (SMV) and necrotic symptom (SMV-N). The average yield of “oseo”was 2.51 ton per hectare in the regional yield trials (RYT) for double cropping carried out for three years from 2005 to 2007.

A new covered barley variety, “eungangbori”was developed from the cross between Milyang 55 which have lodging tolerance and easy brittleness and Suweon 260 with good quality by barley breeding team in the Yeongnam Agricultural Research Institute (YARI) in 2002. A promising line, YMB3855-3B-14-1-1-1, was selected in 1999. It was designated as the name of Milyang 110. It was prominent and had good result from regional adaptation yield trials (RAT) for three years from 2000 to 2002 and released as the name of “eungangbori” Geungangbori is resistant to barley yellow mosaic virus and moderately resistant to powdery mildow. The average maturing date was same with Olbori on paddy field in regional adaptation yield trials for 2000-2002. Its culm length is 17 cm shorter than that of Olbori and the spike length is 4.4cm, it’ longer than olbori. The 1,000 grain weight of Geungangbori was 34 g, same as Olbori, but the number of spikes per m2 and test weight ware lower than those of Olbori. The yield potential of Geungangbori was 4.22 MT/ha on paddy in regional adaptation yield trials for 2000-2002. which was 7% higher than that of Olbori. The cooking quality of Geungangbori were similar to Olbori such as water absorption rate and expansion rate. But the crude protein content is lower than Olbori. This variety is suitable for double cropping system with rice in the southern part of the Korean Peninsula.

A new mungbean cultivar Daseon (Vigna radiata (L.) Wilczek) was derived from the cross between KM9003-2B-783 and Keumseong at the Jeollanamdo Agricultural Research ＆ Extension Services (JARES) in 2006. Daseon has erect growth habit, heart leaflet, greenish purple hypocotyl, black and straight pod when matured, and dull green seed surface. A thousand seed weight was 52 g, sprout yield ratio was 630%, and the anthocyanin (delphinidin 3-glucoside) of fresh sprouts contained 1.7 ug/g. The average plant height was 2 cm shorter than the check cultivar (Owool). It is field resistance to mungbean mottle virus, cercospora leaf spot, and powdery mildew. The average yield was 1.76 ton/ha, which was 21% more than check cultivar.

Biomass crops have potential as a source of renewable CO2-neutral energy to ease concerns about fossil fuel consumption. Therefore, there is an increasing interest in high biomass crops such as switchgrass (Panicum virgatum L.). Switchgrass is a perennial C4 grass that requires low cost for biomass production. In the previous study, we evaluated forty-six switchgrass germplasms for biomass yield and classified the germplasms into the high-, medium-, and low-yielding groups. In this experiment, we analyze physiological characteristics affecting biomass productivity and composition of organic compounds for the two selected lines from each biomass yield group. Among the characteristics related to carbon assimilation, photosynthetic rate, real CO2 absorption rate(Delta CO2(CO2 reference - CO2 analysis(corrected for dilution))), P.A.R incident on leaf surface, and chlorophyll content were positively related to biomass yield of the selected lines. Positive correlation was found between biomass yield and ash content but no relations were found between biomass yield and content of organic compounds such as lignin, glucose, crude protein, cellulose, holocellulose, hemicellulose, ADF, and NDF. This study was supported by Technology Development Program for New Bioenergy(subject number-20070301030016), Rural Development Adiministration, Republic of Korea.

KNU corn breeding team in collaboration with International Corn Foundation (ICF) is dedicated to develop super corn hybrids for developing countries like Nepal and Cambodia. The team works to develop high bio-energy maize hybrids for Korea. Crossing of temperate with tropical germplasm shows new heterotic patterns. Four tropical inbred lines from IITA, Nigeria, ten sub-tropical lines from Nepal and two temperate lines (P45 and 69B) from Korea were crossed to produce single-cross hybrids. Besides, four single-cross hybrids from Nepalwere crossed with P45 and 69B to produce three-way crosses. Gray leaf spot (Cercospora zea-maydis) being the most important problem of corn in mid-hills of Nepal, GLS resistant materials from IITA were crossed with Nepal materials in Cambodia to produce GLS tolerant hybrids. Single-cross hybrids were evaluated at ICF Agriculture Center in Cambodia and KNU farm, Gunwi in Korea in 2008. The three-way crosses were planted at Gunwi farm and the GLS resistant materials were planted at Khumaltar station of Nepal Agricultural Research Council, Kathmandu. Crosses of Tzi-25 with RML-4 and RL-111 and RL-105xNML-2 were found outstanding in Cambodia. Four tropical x subtropical hybrids (Tzi-18xRML-4, Tzi-18xRL-14, Tzi-25xRL-14 and RL-47xTzi-25), four temperate x subtropical hybrids (P45xRL-111, P45xRML-8, RML-5x69B and 69BxRL-105). P45xGaurab was the most suitable for both grain and biomass production.
