15-16: Miscanthus plant named Geodaeuksae #1 for biomass production

We had developed miscanthus plant named Geodaeuksae#1 for high biomass production.  Geodaeuksae#1 was selected plant from wild population in southern part of Korea.  Taxonomically the plant is belonging to M. sacchariflorus which is native in East Asia including Korea.  By counting chromosome number with microscope, the plant was identified to tetraploid which chromosome numbers are 76.  Heading date of Geodaeuksae#1 is 7^th Oct. which is 10 days later than normal M. sacchariflorus. This long vegetative growth duration can be positive to high biomass yield.  Stem and rhizome of Geodaeuksae#1 are 10.3mm and 11.3mm respectively which are thicker than those of normal M. sacchariflorus which are 5.9mm and 7.2mm respectively. The stem length of Geodaeuksae#1 is about 400cm which is longer than one of normal M. sacchariflorus, 265 cm. The dry matter yield of Geodaeuksae#1 is 30ton/ha which is 50% higher than normal M. sacchariflorus.  The content of cellulose and hemicelluloses in Geodaeuksae#1 is 44.0% and 27.5% respectively which is also higher than that of normal M. sacchariflorus.  Ash content of Geodaeuksae#1, 1.5%, is less than that of normal M. sacchariflorus.  Because of those good characteristics of Geodaeuksae#1, this giant miscanthus can be a promising feedstock for cellulosic bioethanol in Korea.
