         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.

        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.
