| Research Abstract |
The common ecotype of cogongrass, a perennial grass, is distributed in southern parts of Tohoku region and southward, Japan and the early ecotype is mainly in northern parts of Tohoku region and Hokkaido. The common and early ecotypes collected in early 1980’s and 2009 to 2011 in Tohoku region were distinguished by GOT zymogram and trnL-F region polymorphism of chloroplast DNA to clarify range expansion of the common type resulted from global warming. The hybrids between the common and early ecotypes were widely distributed in northern parts of Tohoku region
