“…Cluster analysis based on Nei (1972) distances separated, with some exceptions, the genotypes according to their row type. Our results correlate with previous studies showing a clear separation between two-and six-row types (Usubaliev et al 2013;Chaabane et al 2009;Chen et al 2009;Lasa and Igartua 2001;Franckowiak and Lundqvist 1997). Historically, in ICARDA, breeders had made several two-by-six row crosses which was evident in this study by the identification of admixtures (Fig.…”

Plant breeders are interested in using diverse genotypes in hybridization that can segregate for traits of importance with possibility of selection and genetic gain. Information on molecular and agromorphological diversity helps the breeders reduce the effort for parental selection and helps the advancement of generations. A phenotypic and molecular diversity study, using 24 traits (agronomic and disease) and 6519 SNPs in a diverse collection of 336 spring barley genotypes, was carried out at Marchouch and Jemma Shiam research stations in Morocco. Based on structure and multivariate analyses, strong differentiation between the two-and six-row types were observed. The linkage disequilibrium (LD) decay of the current collection (for the combined population) was up to 3.58 cM (r 2 = 0.15) while LD decay were estimated 3.91 and 2.36 cM for two-and six-row barley, respectively. PCA of agro-morphological traits revealed grain per spike, net form of net blotch (NFNB), spot form of net blotch (SFNB), and 1000 kernel weight were the most discriminatory traits in the current collection. Association mapping in the two independent populations will be ideal for identification of markers, and QTL related to traits. The generated information on relatedness between individuals will help identify diverse genotypes for breeding programs.

“…Furthermore, cultivation of heterogeneous accessions is advantageous for farmers since it lowers the risk for complete yield loss in case of unfavorable growing conditions, shortage of fertilizers and lack of plant protection measures. A similar situation was observed in barley accessions collected from farmers’ fields in Kyrgyzstan, indicating seed mixtures (Usubaliev et al ).…”

Evaluation of microsatellite-based genetic diversity, protein and mineral content in chickpea accessions grown in Kyrgyzstan

et al. 2014

The genetic diversity of 23 chickpea accessions representing Kyrgyz landraces and cultivars, ICARDA breeding lines, Spanish and Turkish cultivars was characterized using nine microsatellite (SSR) markers which generated a total of 122 alleles. The number of alleles (Na) per locus varied from 9 to 20. The observed heterozygosity (Ho) ranged between 0.05 and 0.43 (average 0.13) whereas both the expected heterozygosity (He) and polymorphic information content (PIC) ranged from 0.71 to 0.90 (average 0.83). Analysis of molecular variance (AMOVA) showed that 62% of the total genetic variation was found within accessions while the remaining 38% was found among accessions. Principal coordinate analysis (PCoA) indicated the presence of two groups. The two Kyrgyz cultivars were found apart from these groups. Cluster analysis generally confirmed the results of PCoA and also separated the Kyrgyz cultivars from the subcluster formed by Kyrgyz landraces and the subclusters formed by breeding lines from ICARDA along with landraces from Turkey and Spain. In addition, protein content and mineral concentration were determined. Protein content and mineral concentrations for Ca, S, Mg, P, K, Fe, Mn, Cu and Zn varied significantly among accessions. The results show that Kyrgyz germplasm provides a source of diversity for improvement of chickpea.

“…The genetic distinctiveness of these two types of barley was indicated, among others, by tests performed for 336 ICARDA accessions, 116 accessions representing five Chinese eco-geographic populations and 175 accessions from the Spanish barley core collection [28,48,49]. However, there are also reports where such a clear division was not observed, e.g., analysis of spring barley accessions from Kyrgyzstan [50]. Moreover, there were some overlaps between two-and six-row barley in the ICARDA collection [28].…”

The extensive genetic diversity of crop landraces deposited in gene banks is an important part of future breeding programs. However, in order to exploit this potential, it is necessary both to preserve germplasm and to collect and share a wide range of data on its characteristics and evaluation. The main objective of the presented paper was to evaluate the diversity of spring barley landraces originating from Poland. Historical data from standard field evaluation of agronomic traits, genetic data obtained from Inter Simple Sequence Repeat (ISSR) analysis and grain morphometric data were used. The analysis showed that groups of hulled and hulls barley accessions were substantially separate. Genetic and grain morphological variation did not show any relationship with eco-geographical conditions in the place of origin. There was also no clear division into forms with two- and six-row ears. The combination of the results of various types of analyzes describing this collection makes us believe that its chances of being used in research and breeding will increase.
