Barley Genotypes

In 2008-2011, grain yield and chemical composition were assessed in a set of spring barley genotypes with standard and changed amylose/amylopectin ratio (non-waxy and waxy, respectively) at two locations (Kroměříž, Žabčice). Genotypic as well as environmental effects were important for the variations in contents of chemical compounds. The waxy genotypes had statistically significantly higher levels of β-glucans and protein (6.9% d.m., 12.1% d.m., respectively) than genotypes with the standard starch character (5.4% d.m., 11.5% d.m., respectively). The hull-less waxy genotype KM2619.413.4 was statistically significantly different from all other genotypes in the set due to its highest content of β-glucans (10.80% d.m.). We found statistically significant differences between genotypes divided by the type of grain (hulled vs. hull-less) and also by the starch character (standard vs. waxy) in average starch contents as follows: hull-less genotypes with the standard starch composition (64.8% d.m.) > hull-less waxy genotypes (63.7% d.m.) > hulled genotypes with standard starch composition (61.4% d.m.) > hulled waxy genotypes (60.0% d.m.). Genotypes with elevated grain constituents (higher starch and BG contents) could be important from the point of a prospective use of barley for food production as was already found for example in the hulless waxy genotypes KM2645.412.3.4.6 (63.7% and 8.0%, respectively) and KM2551.469.1-2 (64.1% and 7.0%, respectively).

And Storage

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.

Growing Environment

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.
