Mankind has been involved in improving the quality and produtivity of crops ever since it bean using plants as food, fiber, and medicine. At first, early farmers selected the seeds of the best plants for replanting. However, when the science of genetics was discovered prior to the turn of the century, the ability to enhance plants was increased significantly. The basis of modern agriculture was norn as plants were cross-bred to produce new varieties with desirable characteristics such as higher yields or resistance to diseases. The next advance in plant improvement came with the development of hybridization of plant species starting in the 1920s. These conventional processes for plant improvement were relatively slow and imprecise. Cross-breeding plants takes years of trial and selection to achieve desired characteristics and to eliminate undesired ones, In the past ten years, since has developed a way to speed up the process of plant improvement and to make it much more precise.
