PLANT GENETIC RESOURCES FROM THE BALKAN PENINSULA IN THE WORLD’S GENEBANKS

An overview is given of plant genetic resources that originate from countries of the Balkan Peninsula and are preserved in genebanks worldwide. For each country, the number of genebanks holding ma-terial from this country, and the number of accessions are presented. A summary is also provided by crops (scientific names). The survey is based on databases such as FAO WIEWS (World Information and Early Warning System), EURISCO (European search catalogue for plant genetic resources), and Genesys (worldwide database on plant genetic resources)

Genetic differentiation and geographical Relationship of Asian barley landraces using SSRs

Genetic diversity in 403 morphologically distinct landraces of barley (Hordeum vulgare L. subsp. vulgare) originating from seven geographical zones of Asia was studied using simple sequence repeat (SSR) markers from regions of medium to high recombination in the barley genome. The seven polymorphic SSR markers representing each of the chromosomes chosen for the study revealed a high level of allelic diversity among the landraces. Genetic richness was highest in those from India, followed by Pakistan while it was lowest for Uzbekistan and Turkmenistan. Out of the 50 alleles detected, 15 were unique to a geographic region. Genetic diversity was highest for landraces from Pakistan (0.70 ± 0.06) and lowest for those from Uzbekistan (0.18 ± 0.17). Likewise, polymorphic information content (PIC) was highest for Pakistan (0.67 ± 0.06) and lowest for Uzbekistan (0.15 ± 0.17). Diversity among groups was 40% compared to 60% within groups. Principal component analysis clustered the barley landraces into three groups to predict their domestication patterns. In total 51.58% of the variation was explained by the first two principal components of the barley germplasm. Pakistan landraces were clustered separately from those of India, Iran, Nepal and Iraq, whereas those from Turkmenistan and Uzbekistan were clustered together into a separate group

Chromosomal passports provide new insights into diffusion of emmer wheat

PubMedID: 26024381Emmer wheat, Triticum dicoccon SCHRANK (syn. T. dicoccum (SCHRANK) SCHÜBL.), is one of the earliest domesticated crops, harboring a wide range of genetic diversity and agronomically valuable traits. The crop, however, is currently largely neglected.We provide a wealth of karyotypic information from a comprehensive collection of emmer wheat and related taxa. In addition to C-banding polymorphisms, we identified 43 variants of chromosomal rearrangements in T. dicoccon; among them 26 (60.4%) were novel. The T7A:5B translocation was most abundant in Western Europe and the Mediterranean. The plant genetic resources investigated here might become important in the future for wheat improvement. Based on cluster analysis four major karyotypic groups were discriminated within the T. dicoccon genepool, each harboring characteristic C-banding patterns and translocation spectra: the BALKAN, ASIAN, EUROPEAN and ETHIOPIAN groups. We postulate four major diffusion routes of the crop and discuss their migration out of the Fertile Crescent considering latest archaeobotanical findings.: © 2015 Badaeva et al.Russian Foundation for Basic Research: 14-04-00142
