Crop yield breeding is to improve the genetic characteristics of crops, in order to cultivate high-yield and high-quality varieties of technology. Also known as crop variety improvement. It is based on the theory of genetics, and the comprehensive application of plant ecology, plant physiology, biochemistry, plant pathology and biostatistics and other disciplines. It is a low investment and high benefit biotechnology, the development of plantation production is of great significance.
