Ramie Urticaceae is a perennial perennial plant root, with strong fecundity. This article ramie breeding methods are summarized as follows: the success rate of seed breeding lower, after planting can not benefit within a few years, commonly known as “three-year planted hemp poor.” The reason is ramie cross-pollinated, natural high rate of outcrossing, progeny of seedlings separated severely, variability larger, the original ramie fiber quality and yield
