Genetic Characterization of the Norwegian Apple Collection

Round 1

Reviewer 1 Report

An interesting publication describing the research on the genetic diversity of the collected genotypes of apple and their origin. In the introduction, give some details marked in the text. Well-described research methodology. Numerous editorial errors in the spelling of the names of species and varieties, without giving the author of the Latin name or its incorrect spelling. In the summary, you can give the names of particularly valuable genotypes, or what valuable features the collected individuals have, all at the level of generalizations.

Reviewer 2 Report

The article “Genetic Characterization of the Norwegian Apple Collection” was studied by using SNP polymorphism. This article provides some important research information. It has very important research value. It also provides useful reference for breeding of horticultural plants (apple).  Minor problems: The author should list the plant materials used in this study, including sampling location, plant characteristics, genetic background, etc.

 

How to select the favorable results of apple plant resources from 12517 SNPs? 

 

The font in Figure 4b is too small to read clearly. It is recommended that author specify or annotate different clusters.

 

In Figure 5, several groups of representatives have similar colors. It is very confusing and difficult to read the picture.

 

The conclusion say, SSR markers were useful for first screening of the material preserved in the Norwegian Apple Collection. However, I did not see the result or process of SSR screening in the article.

 

The authors should validate these important SNPs.
