玉米是重要的粮食和饲料作物,也是现代食品、医药、化学工业的重要原料作物。所以,加快玉米育种的进程,提高玉米的产量和质量是育种工作者迫切解决的问题。近年,随着分子生物学的迅速发展,遗传标记技术在玉米育种中也得到了广泛的应用,并且遗传标记的种类和数量也发生了显著的变化,即在原有的形态标记、细胞标记、生化标记基础上增加了分子标记。
Corn is an important food and feed crop and is also an important raw material crop in modern food, pharmaceutical and chemical industries. Therefore, to speed up the process of corn breeding and improve the yield and quality of maize is a problem that breeders urgently solve. In recent years, with the rapid development of molecular biology, genetic marker technology has also been widely used in maize breeding, and the types and numbers of genetic markers have also undergone significant changes, that is, in the original morphological markers, cell markers, biochemical Marker based on the addition of molecular markers.
