Fig. 5. Test for the potential gene flow from genetically modified (GM) grass to wild-type (WT) grasses within a 3-km radius during a 2-yr period from 2003 to 2005. The GM grass field is centrally located in the Wimi-Ri test field in Nam Jeju County. The sampling sites shown were randomly chosen where Zoysia grasses grew. The sampling site distribution is biased in the north easterly direction from the GM grass site, whereas other directions are less favorable for grass growth due to geo-topographic factors (volcanic rocks, bushy jungles, forest, etc.).
