Modification of grain, vegetable, and fruit crops has been done for centuries through traditional cultivation methods. From early times, farmers would modify crops through careful selection of favored traits and cross-breeding of those selected plants. Today, this traditional technology continues with modern tools that allow the rapid selection of plant lines for hybridization, the rapid detection of desirable traits, and the confirmation of successful plant crosses. In addition, new technologie…
