“…Also other studies on related Brassica crops have shown low or no correlation between molecular marker analysis and morphological studies, e.g. AFLP markers (Qi et al, 2008) and RAPD markers in Brassica napus (FahMi et al, 2012). The results in our studies are in line as well with the study made by toMsone et al (2012), where Latvian horseradish accessions have been evaluated according to the phenol content and molecular markers (RAPD analysis).…”

Morphological diversity was studied in 101 accessions of horseradish (Armoracia rusticana) collected from old gardens in Denmark, Norway, Finland and Sweden. The characterization work was performed over three years, where a total of 19 descriptors from the UPOV guidelines TG/191/2-2001 were recorded each year. The results showed high diversity among the studied accessions, both for leaf and rhizome characters. A morphotype with long leaves and a high leaf length/leaf width quota was the most common, but also elliptic and heart-shaped leaf types were found. Some characters showed stability over the years, although there were variations in the results. Correlations between descriptors were found and five different clusters of descriptors were identified. In two of the clusters, only leaf characters were found, whereas the rhizome characters were divided into three other clusters. Correlation between descriptors can be used to reduce the number of descriptors for further studies of horseradish. The results showed that there is a high diversity both in leaf and rhizome characters, despite that horseradish is a vegetatively propagated plant.

“…For erucic acid content, only moderate association was found with UBC 137_750. This is in agreement with the results of other authors who found no association between the phenotypic and morphological traits and the RAPD markers (BURLACU et al, 2011;FAHMI et al, 2012;PAULAUSKAS et al, 2013).

“…RAPD analysis combined with cluster analysis was found to be an adequate method for genetic characterization and grouping of many plant species, including rapeseed (FAHMI et al, 2012) and these markers can also be useful in taxonomic studies (DIMITRIJEVIĆ et al, 2014). Our results of cluster analysis showed a concordance between the position of varieties in the cluster and their pedigree information, but also enabled separation of spring and winter varieties ( Figure 2).…”

“…Genetic diversity estimates were considerably high for B. napus L. as it was observed in previous studies (Fahmi et al, 2012;Fazeli et al, 2008;Hasan et al, 2006;Marjanovic et al, 2009;Moghaddam et al, 2009;Qu et al, 2012). In addition, slightly higher genetic diversity was observed in the harvested varieties than the varieties provided by the commercial companies.…”

In cultivated commercial crop species, genetic diversity tends to decrease because of the extensive breeding processes. Therefore, germplasm of commercial crop species, such as Brassica napus L. should be evaluated and the genotypes, which have higher genetic diversity index, should be addressed as potential parental cross materials in breeding programs. In this study, the genetic diversity was analysed by using randomly amplified polymorphic DNA analysis (RAPD) technique in nine Turkish commercial rapeseed varieties. The RAPD primers (10-mer oligonucleotides) produced 51 scorable loci, 31 loci of which were polymorphic (60.78%) and 20 loci (39.22%) were monomorphic The RAPD bands were scored as binary matrix data and were analysed using POPGENE version 1.32. At locus level, the values of genetic diversity within population (H s ) and total (H T ) were 0.15 and 0.19 respectively. The genetic differentiation (G ST ) and the gene flow (N m ) values between the populations were 0.20 and 2.05 respectively. The mean number of alleles (n a ), the mean number of effective alleles (n ae ), and the mean value of genetic diversity (H e ) were 2.00, 1.26, and 0.19 respectively. According to Pearson's correlation, multiple regression and principal component analyses, eco-geographical conditions in combination had significant effect on genetic indices of commercial B. napus L. varieties were discussed.
