“…This is probably due to the farmers' preferences and the lack of cultivation tradition of oats with dark lemma. Diederichsen (2008) also observed a lower than expected frequency of dark lemma accessions in Eastern Europe.…”

“…In the presented study within the 67 accessions there were five botanical varieties according to the classification by Rodionova et al (1994). However, if we applied the grouping criteria set out by Diederichsen (2008) that number of groups would decrease to three. The low level of morphological diversity could explain somehow the high genetic similarity of test accessions.…”

“…Analysis of genetic variation carried out for 670 accessions from 79 countries indicated that the highest level of variation occurred within those obtained from Russia and the Unites States, while, the accessions from Mediterranean basin were characterized by the highest genetic distinctiveness (Fu et al 2005). The analysis of genetic diversity within a world collection of cultivated hexaploid oat based on qualitative morphological characters of the 10,105 accessions from 85 countries showed the presence of 118 morphological groups (Diederichsen 2008). In these studies, the region of Eastern Europe was characterized as the third largest in terms of diversity.…”

“…In these studies, the region of Eastern Europe was characterized as the third largest in terms of diversity. The accessions from the Poland were divided into 15 groups, which indicated that Polish collection was the most varied in the region (Diederichsen 2008). In the presented study within the 67 accessions there were five botanical varieties according to the classification by Rodionova et al (1994).…”

All over the world about 220,000 accessions of the genus Avena is preserved in gene banks. Polish oats collection, in the National Centre for Plant Genetic Resources, consists of about 2,500 accessions. More than 80 % of them belong to the species Avena sativa. Only 136 accessions have the landrace or traditional cultivar status and 91 of them were collected in Poland. The main objective of this study was to estimate genetic diversity of a set of 67 Polish landraces using inter simple sequence repeat (ISSR) markers. We also tried to determine whether genetic diversity depended on the region and altitude of collection site and if there was a relationship between DNA polymorphism and some morphological traits. The accessions were collected between years 1973 and 1999 from areas of Northern, Southern and Eastern Poland. The obtained results indicated a relatively low diversity (0.09-0.37) of the common oat landraces. Analysis of molecular variation (AMOVA) showed that there were no significant differences within designated geographic regions. It indicated that at the same time the altitude of collection site had significant effect on the genetic differentiation of the accessions. AMOVA also showed the presence of variance between groups formed on the basis of the colour of lemma. White lemma accessions were also characterized by highest genetic distinctiveness. Considering the evident impact of local climatic conditions on the genetic distinctiveness of Polish landraces utility of them in the Polish breeding programs should be considered.

“…Morphological traits are considered easy to observe, and it is possible to screen and categorize large amounts of genotypes at a low cost, which is a great advantage when managing large germplasm collections (Diederichsen, 2008). However, the optimal utilization of morphological descriptors involves the evaluation of agronomic performance in the farm (Zammouri et al, 2009).…”
