Fusarium head blight (FHB) is a barley disease, which occurs every year in various areas of barley cultivation all over the world and the increasing incidence has been confirmed in the Czech Republic also during the last years. We aimed to emply AFLP (Amplified fragment length polymorphism) and SSR (Single sequence repeats) markers to describe diversity among breeding lines with a sufficient level of resistance towards FHB and to find marker(s) associated with the analysed traits. The number of eight accessions including five expected resistance donors and three sensitive lines were tested in the field and laboratory. The field values and the amount of deoxynivalenol were positively correlated (r = 0.92). The laboratory test and content DON manifested also a high correlation (r = 0.73). Several DH lines developed from androgenetic barley progenies of the F1 hybrids between the susceptible line PI 383933 and resistant line PEC 210 or the susceptible line PI 383933 and resistant cultivar Chevron were found resistant towards Fusarium infection in both the field and laboratory tests. Low infestation was found at line DH 37 from combination Chevron × PI 383933 and lines DH48, DH49, DH50 and DH55 from the combination PEC 210 × PI 383933. Cluster analyses based on 68 AFLP and 18 SSR markers demonstrate a genetic relationship among parental genotypes and DH lines.Some DH lines combined a sufficient degree of resistance against FHB and extract content (basic parameters malting quality). Statistically significant differences in malt-extract values were observed between groups of the DH lines possessing and not possessing the AFLP marker CAA/AGC 341bp. The markers will be further evaluated and optionally used for MAS.

Seed longevity of 76 spring barley gene pool samples (Hordeum vulgare L. subsp. distichon, convar. distichon: 56 nutans Schubl., two deficience (Steud.) Koern., two erectum Rode ex Shuebl., two medicum Koern.; convar. nudum (L.) A.Trof.: one nudum L. та subsp. vulgare: convar. vulgare: nine pallidum Ser., three rikotense Regel.; convar. coeleste (L.) A.Trof.: one coeleste (L.) A.Trof.) from 26 countries, 11 years and four places of reproduction was analyzed. Seeds with 5–8% moisture content were stored in chamber with unregulated and 4oC temperature. The possibility of seed storage under these conditions for at least 10 years without significant changes in germination has been established. The importance of meteorological conditions in the formation and ripening of seeds for their longevity is confirmed. The relationship between the decrease of barley seeds longevity and storage conditions, amount of rainfall, temperature regime during the growing season of plants is discussed.

Arabinoxylan and beta-glucan contents are limiting factors for a wider use of barley production. Arabinoxylan and beta-glucan contents were assessed in grain samples in sets of seven malting hulled varieties, three hull-less lines and one hull-less spring variety grown in the localities of Branišovice, Žabčice, and Kroměříž in 2009 to 2011. Further, the effect of growing technologies on the level of these non-starch polysaccharides was studied. Variability of arabinoxylan contents was affected most significantly by a genotype and growing technology whereas variability of beta-glucan contents was mostly affected by a genotype and growing environment (interaction of year with locality). The highest values of arabinoxylans and beta-glucans were determined in the grain samples of hull-less lines (KM 1057: 6.16% of arabinoxylans and KM 2084: 6.41% of beta-glucans) and on the contrary, the lowest values of arabinoxylans were found in the grain of hull-less variety AF Lucius (3.85%) and lowest amounts of beta-glucans were found in malting variety Radegast (3.92%). The samples of the growing technology without fungicide treatment had on average more arabinoxylans and beta-glucans than the fungicide non-treated ones.

Salinity Resistance

Abstract The results of salinity resistance assessment of 5 spring barley ranges (Hordeum vulgare L.) Grass family (Poaceae) - Yaromir, Nadezhny, Znatny, Zlatoyar, and 9 types of own plant-breeding lines which are supposed to be perspective for the future use are given in this article. NaCl impact in the concentration of 0.7 and 0.9 mPa (0.98 and 1.26% NaCl) on seed germination and morphological indicators such as length and quantity of roots, length of seedlings were studied. The salinity stress resulted in the inhibitions of the roots length and seedlings in the provocative background if to compare with the control group background samples. At the concentration of 0.7 mPa salinity resistance value varied from 62.4 to 96.6% which corresponds to 1-2 salinity resistance groups. At the concentration of 0.9 mPa salinity resistance varied from 27.9 to 80.8% which corresponds to 1-3 salinity resistance groups. The yield capacity and adaptive qualities were examined on the initial data basis. Thus, there was a correlation dependence at both of sodium chloride concentrations revealed between the yield capacity of the field experience samples and the laboratory test samples.
