A sample of 480 bread wheat varieties originating from 15 European geographical areas and released from 1840 to 2000 were analysed with a set of 39 microsatellite markers. The total number of alleles ranged from 4 to 40, with an average of 16.4 alleles per locus. When seven successive periods of release were considered, the total number of alleles was quite(More)
The correctness of the genealogical approach to the estimation of genetic diversity has been substantiated. The approach implies a comparison of the estimates of similarity based on genetic markers and coefficients of parentage. A method of the application of the genealogical approach to the formation of the core collection has been developed. The adequacy(More)
Hulled wheat species (einkorn, emmer, spelt) are presumed to be an alternative to bread wheat in organic agriculture since the yield penalty is less pronounced under organic farming and generally higher prices can be achieved for specialty grains. The present study analyzed differences between wheat species with respect to biomass production, harvest index,(More)
Organic farmers look to the possibilities of growing neglected crops, such as the spring forms of hulled wheat – einkorn, emmer and spelt – for support in developing the organic farming system. In 2008, 169 landraces from the gene bank at the Crop Research Institute in Prague were tested on certifi ed organic plots. The experiment was aimed at fi nding(More)
Mother of FT and TFL1 (MFT) participates in the regulation of seed dormancy in wheat. A single-nucleotide polymorphism (SNP) in the promoter of MFT on chromosome 3A (MFT-3A) can explain the difference in the levels of MFT-3A expression, and the difference in seed dormancy, between Chinese Spring (CS) and the CS line with a substituted chromosome 3A from(More)

Organic farmers have become more interested in the marginally grown (neglected) cultivars, as spring forms of the hulled wheat varieties (eincorn, emmer wheat, spelta wheat) or intermediate forms of the soft wheat. 173 land races from the gene bank at the RI in Praha-Ruzyně were grown on the organic certified parcel and evaluated in 2008. The trial aimed to(More)
Wheat genetic resources may be grown in organic farming systems or in less favourable areas for bread wheat species. Characteristics of hulled wheat species (23 varieties of einkorn, emmer wheat, spelt wheat) were studied and evaluated within a two-year trial period (which was executed on certified organic fields) and they were compared to characteristics(More)
Microgreens from common and tartary buckwheat genotypes were evaluated for total flavonoid content (rutin, quercetine and kaempferol separately), bound phenolic acids content, carotenoids and α-tocopherol content and antioxidant activity. The results have shown that in common and tartary buckwheat microgreens antioxidant activity was found. High level of(More)
