The research progress in genetic linkage map construction of forest tree species both at home and abroad were reviewed in the paper.Two main problems involved in the field were discussed.One was the limitation of the number of individuals of mapping populations and the other was the random markers mostly employed by the majority of studies.These problems have resulted in crossing combination specificity in the constructed maps and the QTLs located on the basis of the maps.As a result,the QTLs discovered up to now have low credibility and poor practicability in marker-assisted selection.
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。

The key to feature extraction is to select the optimal feature combination from all the features. In this study, the optimal color feature combination,{/G,(R+4G+B)/6, H variance, S variance}, is selected using genetic neural network at first. Then the main texture features including the mean, variance, energy and entropy of the cooccurrence matrix, the secondary texture features including the maximum frequency number, absolute uniform, inertia and importance of the co-occurrence matrix are extracted.
