Abstract:A new method called as “crossing method” was proposed in this paper for evaluating the transgenic impacts on plant genetic diversity. In this crossing method, the transgenic plant and its wild type (populations or species with a same genetic background, except the foreign gene) were crossed by using representative plants (cultivars) group and the impacts of transgenics on plant genetic diversity were evaluated based on the genetic variations of important agronomic characters among their offsprings. In our e...
