“…A. strigosa is a self-pollinating species or it may prove that the genetic pool of this species is quite narrow. The values of PIC coefficient were consistent with literature data, however, they were lower than those obtained by using ISSR markers for eight sand oat accessions [14]. This is probably due to differences in the type of analysed genome regions i.e.…”

“…Tis kind of information, especially in case of self-pollinating plant species, can be the first indicator of internal accession diversity and can be used as a genetic integrity marker. Botanical differentiation at sub-species level has been identified earlier, for example for Avena sativa L., A. strigosa and Triticum monococcum L. [14, 32, 33]. Among the 56 accessions investigated here, only seven out of 17 botanical varieties were found.…”

“…below 0.05. In our earlier study, only two (ACP and MDH) out of the same 12 systems, showed the presence of varied alleles in eight landraces of sand oat [14]. In Kubiak’s paper [8], in which 19 A. strigosa ecotypes were analysed, only two (MDH and EST - esterases) out of six applied systems showed polymorphism.…”

“…In the phylogenetic study of Festuca-Lolium complex all obtained fragments were polymorphous [55]. A lower detected level of polymorphism may result from the analysis of pooled samples from accessions with a high level of internal variability [14]. However, it may also result from the flowering biology, i.e.…”

Background Sand oat ( Avena strigosa Schreb.), one of the four cultivated species of the genus Avena, could be considered as another alternative crop. In gene banks 865 germplasm samples of this species have been preserved that have not been thoroughly investigated so far. The results of phenotyping (36 traits), isoenzymatic (12 systems) and genetic (8 pairs of Sequence-related amplified polymorphism markers) variation were used to obtain the complete description of 56 accessions diversity originated from different parts of world. Results Breeded and weedy forms represented similar pool of morphological traits that indicated a short-term and extensive breeding process, albeit all accessions which we classified as cultivated were characterized by better grain and green mass parameters compared to the weedy ones. Isoenzymes showed relationships with geographical origin, which was not possible to detect by SRAP markers. There was no similarity between morphological and biochemical results. The polymorphism level of SRAP markers was lower than indicated by the available literature data for other species, however it may result from the analysis of pooled samples of accessions with a high internal variability. The extensive type of breeding and its relatively short duration was also reflected in the population structure results. Joint analysis revealed that a secondary centre of diversity is being created in South America and that it has its genealogy from the Iberian Peninsula. Conclusions Despite the relatively large representation of this species is in various gene banks, it is highly probable that the vast majority of stored worldwide accessions are duplicates, and the protected gene pool is relatively narrow. Sand oat meets all the requirements for an alternative crop species, but further studies are needed to identify the genotypes/populations with the most favourable distribution of utility and quality parameters.

“…As a consequence, it is very difficult to detect the linkage between the genetic and geographical distance in crops (Boczkowska and Tarczyk 2013 ; Diederichsen 2008 ). However, in the case of minor crops not so intensively bred, the relationship with the region of origin is much more evident (Podyma et al 2017 ; Podyma et al 2019 ). Earlier analyses of rye also indicated a lack of a link between the genotype and place of origin.…”

Common rye (Secale cereale L.) is one of the most important cereals in Europe. Nevertheless, its germplasm collections are among the least numerous compared with cereals. There are only about 27,000 Secale accessions in 70 gene banks around the world. Despite extensive research on the molecular characterization of genetic resources, only a fraction of this collection has been described. The main objective of the presented study was to perform genotypic and phenotypic characterization of an obsolete gene pool represented by 100 accessions originated from 28 countries around the world and preserved in the gene bank of the Polish Academy of Sciences Botanical Garden – Center for Biological Diversity Conservation in Powsin. Genetic analysis using simple sequence repeat markers showed that the obsolete gene pool is relatively large. This indicates that different sources of variability were used in breeding programs. However, the genetic variation is in no way related to the place of origin. Despite the great differences in the genetic make-up, the collection showed a broadly common phenotype. This could result in a low level of interest among breeders in the stored germplasm, undervalued as a source of important but not easily observable traits, e.g., high disease resistance, which was found in some accessions.
