A plant breeding cycle would be called a 'generation' in people or animals. A plant breeding cycle begins with pollination, and the subsequent production of true seed. It ends when the next pollination occurs among selected plants that become the parents of the next breeding cycle. Most breeding programs require some 10-15 breeding cycles. In the temperate regions, there will normally be one breeding cycle each year but, with potatoes, it may be possible to complete two breeding cycles each year (see 180-day breeding cycle).
