林木遗传连锁图谱构建研究进展与发展方向Research Progress in Forest Tree Genetic Linkage Map Construction and Its Future Prospects
遗传连锁图谱 QTL定位 表达序列标签多态性（ESTP） 比较作图
2008/1/16
摘要本文就目前国内外林木连锁遗传图谱领域的研究进展进行了综述，指出了该领域研究中存在的主要问题，即一方面是作图个体的数量有限，另一方面是采用的标记以随机标记为主，导致了建成的图谱以及利用图谱获得的数量性状基因位点（QTLs）信息具有杂交组合特异性，造成了QTLs的可信度和在林木遗传改良以及标记辅助选择中的实用性降低等现象。针对存在的问题，讨论了根据林木生物学特点选择合适遗传标记的意义，指出进行林木...
