The origin of the heterochromatic regions on the long arm of maize B chromosome was studied in two ways: the Southern signals of the CL-repeat; and its deletion, insertion, and mutation variants.

本研究分别以CL-repeat的南方杂合讯号以及因缺失、插入和突变造成的序列变异两个角度，来探讨玉米B染色体长臂远端异染色质(distal heterochromatin， DH)区的起源。

中文摘要本研究分别以CL-repeat的南方杂合讯号以及因缺失、插入和突变造成的序列变异两个角度，来探讨玉米B染色体长臂远端异染色质(distal heterochromatin， DH)区的起源。

Clustering was based on SSR markers. Six maize populations were divided into 4 heterotic groups.

根据SSR标记的遗传距离，将供试的6个玉米群体划分成为4大优势类群。

The objectives of this study were: 1 to assess the breeding potential of maize populations including 2 of tropical origin and 7 of temperate origin;2 to find a new heterotic pattern among the 9 populations.

评估2个热带群体和7个温带群体的育种价值，并在这些群体之间寻找新的杂种优势模式，为利用这些种质提供有用的科学信息。

Heterotic grouping of 15 maize inbreds with RAPD markers.

RAPD在玉米类群划分研究中的应用。

Heterotic groups were classified by cluster analysis with RAPDs based on 16 important maize inbreds.

利用RAPD分子标记技术，对16个玉米自交系进行亲缘关系的类群划分。

The six groups classified by cluster analysis of SSR markers is consistent with the available pedigree and the result of combining ability. So it is feasible to analyze the genetic diversity of maize population by SSR markers and to distinguish heterotic group by method of mixed sampling.

6个玉米群体的聚类结果与系谱来源和田间配合力测定结果基本一致，说明，用若干单株混合取样分析玉米群体SSR的遗传多样性，进而对不同玉米群体划分杂种优势类群是可行的。

The principles of several DNA Molecular markers and their application on assessment of germplasm genetic diversity, fingerprinting construction, classification of heterotic groups and heterosis prediction for maize were reviewed.

DNA Molecular markers ； DNA分子标记是继形态标记、细胞标记和生化标记之后发展起来的一类重要的遗传标记，已在生命科学领域中广泛应用。

The principles of several DNA Molecular markers and their application on assessment of germplasm genetic diversity,fingerprinting construction,classification of heterotic groups and heterosis prediction for maize were reviewed.The present problems and prospective of molecular markers application in germplasm resource we...

介绍几种DNA分子标记的原理，综述了DNA分子标记在玉米种质遗传多样性鉴定、绘制指纹图谱、杂种优势类群划分和杂种优势预测等方面的应用，并探讨了在玉米种质研究中存在的问题和应用前景。

Clustering results showed that the clusters were not corresponding to heterotic groups and pedigrees,which suggested that the A-PAGE of seed storage proteins might not be a good method for large-scale analysis of genetic diversity and heterotic grouping in maize germplasm.

利用盐溶蛋白多态性完成的聚类分析结果和自交系系谱及杂种优势群之间没有明显的对应关系，表明储藏蛋白A-PAGE方法对于大规模玉米种质资源的遗传多样性分析和类群划分可能存在局限性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
