自60年代以来，分子标记技术迅速发展，极大地加深了人们对生物遗传规律的认识。在众多的DNA分子标记中，由Willims等（1990）和Welsh等（1990）建立起来的RAPD（RandomAmplifiedPoly-mbrphicDNA，随机扩增多态性DNA）技术，以其快速、准确、灵敏度高等特点，一开始就受到生物
Since the 1960s, the rapid development of molecular marker technology has greatly deepened people’s understanding of the laws of biological genetics. Of the many DNA molecular markers, RAPD (Random Amplified Poly-mbrphic DNA) established by Willims et al. (1990) and Welsh et al. (1990) is characterized by its rapid, accurate and high sensitivity. By the beginning of biological
