... provides vital screens for the development of new cultivars. It is, in addition, the raw material for much of the basic scientific research that generates an understanding of pathogen variation, evolution (on crops and in natural plant populations) and population dynamics. Finally, it constitutes a significant biotechnological resource of particular importance to the genetic engineer. The value ( ...
