Outline of Final Research Achievements |
The intensive use of herbicide glyphosate has resulted in the evolution of herbicide-resistance in several problematic weeds. One of the most problematic weeds is Amaranthus parmeri, which occurs in several states of USA. The USA is the largest import counterpart of crops in Japan and A. parmeri would be inevitably introduced to Japan as contaminants in imported grain commodity. This study were to elucidate (i) glyphosate resistant A. palmeri was established in three major grain-importing ports, (ii) interspecific hybridizations between A. palmeri and other congeneric species were not detected in this study, and (iii) glyphosate resistant trait was inherited to progeny.
