Therefore, the remaining farmers to seize the opportunity to do a good job positioning and selection. Positioning is the selection of crops according to the best genetic advantage of the site for the selection, is a new selection technology. The seeds selected by the positioning and selection method can give all the good performance and traits of a variety to the next generation, so that the performance of the elite seeds can be fully utilized and the stable and high-yielding can be achieved economically and effectively. Several kinds of crop location and selection of the best genetic advantage parts are as follows:
