【摘要】 本文介绍了限制性片断长度多态性 (RFL P)、随机扩增多态性 DNA(RAPD)、扩增片断长度多态性(AFL P)、简单重复序列 (SSR)、染色体原位杂交 (ISH)分子标记的基本原理、特点及其在植物育种中的应用。在植物育种中分子标记可用于绘制品种、品系的 DNA指纹图谱、种质资源遗传多样性的研究、种质资源的创新与鉴定、分子标记辅助选择。更多还原

【Abstract】 The molecular marker principles and characteristics of RFLP,RAPD,AFLP,SSR,ISH and its applications to plant breeding were reviewed.Molecular markers could be used in drawing DNA fingerprint patterns of cultivars,studing genetic diversities of germplasm resources and innovating and identificating germplasm and assisting selection.更多还原
