“…When the value of genetic differentiation among populations is > 15%, the genetic differentiation is substantially high. However, although the value of the genetic differentiation in this study appears to be high according to this criterion, it may not be that high compared to previous studies on einkorn wheat and other primitive landraces (Keskin et al, 2015;Özbek et al, 2011, 2012, 2013Ozbek, 2021). The gene flow and genetic distance data also supported our study.…”

The aim of this study is to investigate genetic diversity in 48 einkorn (Triticum monococcum L. ssp. monococcum) landraces grown in agricultural areas of Bolu and Kastamonu. Therefore, variation in seven agro-morphological traits was investigated. Agro-morphological traits such as leaf weight (mg), coleoptile length (cm), root number (n), root length (cm), fresh root weight (mg), and dry root weight (mg) were examined by the coefficient of variation, ANOVA, and principal components analysis. The highest coefficient of variation (%) was observed in fresh root weight (FRW = 52.09%), while the lowest was in leaf weight (LW = 8.9%). Principal Component Analysis (PCA) was calculated as 76.93% variation in two main components. For molecular characterization, data obtained with iSSR primers were analyzed with the population genetics analysis program PopGene (ver. 1.32). According to PopGene results, the mean number of alleles, the mean number of effective alleles, and average genetic diversity values were calculated as na = 2, nea = 1.33, and h = 0.13, respectively. Among the agro-morphological traits, germination power, root number, and coleoptile length appeared to be reliable traits. The results show that the use of morphological characters alone for genetic diversity in populations is not sufficient to determine the difference between populations and their genetic structure.

This research was carried out to characterize both 200 pure lines selected from Turkish bread wheat landraces and 25 Turkish bread wheat cultivars based on 3 grain quality traits [thousand kernel weight (TKW), protein content (PC), Zeleny sedimentation test (ZSDS)] and 5 mixograph parameters. Univariate and Multivariate(clustering and ordination) techniques were used to investigate the diversity present among the pure lines and cultivars. Both cluster and ordination analyses suggested that there were ten groups of studied genotypes. Applying genotype-by-trait (GT) biplot analysis to the multiple quality trait data revealed that GT-biplot graphically displayed the interrelationships among traits and facilitated visual comparison of pure lines and selection. The results also showed that, based on the quality traits, the pure lines in different groups were belonged to different provinces of Turkey. They were also proved to be highly diverse for 8 quality trait values (both mixograph and grain quality) to breeders and end-users. Especially most of the pure lines had higher PC, midline peak value of mixogram (MPV), midline time x = 8 min integral of mixogram (MTxI) and ZSDS values than some of the cultivars. Also, our results were very contributive in selection of precious pure lines for further breeding programs.

“…Despite having fewer detectable loci than DNA molecular markers, gliadin markers still have great application potential in the identification of genotypes and characterization of genetic relationships between plant germplasms because of their simplicity, speed, and high repeatability (Ma et al, 2012). Hitherto, gliadin has been used as a powerful tool in Apropyron and other Triticeae species to reveal genetic diversity and population differentiation and to elucidate phylogenetic relationships and taxonomic problems (Che and Li, 2007;Özbek et al, 2011). The objectives of this study were therefore to detect genetic diversity and examine inter-or intraspecific systematic relationships among the Agropyron accessions.…”

ABSTRACT. Agropyron Gaertn. is the most important genus in Triticeae (Poaceae), which includes many forage grasses with high economic value. The genetic diversity and relationships of 36 accessions from five crested wheatgrass species were analyzed by gliadin markers. A total of 54 product bands were detected after acid polyacrylamide gel electrophoresis (A-PAGE), of which 100% were polymorphic. The genetic similarity coefficient based on Nei-Li's method ranged from 0.065 to 0.755 with an average of 0.451. The Shannon diversity information index showed that there was a high level of genetic diversity among the accessions. An unweighted pair group method with arithmetic average (UPGMA) dendrogram was constructed based on the Nei-Li's genetic similarity coefficients, which showed the phylogenetic relationships among accessions of different species. Analysis of molecular variance (AMOVA) showed that the proportion of variance explained by inter-and intraspecific variance was 9.34 and 90.66%, respectively, which revealed that the genetic variations within species were higher than the variations among species. Based 5705 ©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 12 (4): 5704-5713 (2013) Genetic diversity in Agropyron species on pairwise genetic distances (Φ ST ) among species, the cluster analysis indicated that A. mongolicum had a low-affinity relationship with other species, while A. fragile showed a close relationship with A. cristatum ssp pectinatum. Finally, the implications of the results for the taxonomy of Agropyron were discussed.
