“…Grain yield and quality traits of spring barley can vary greatly due to growing conditions (Leistrumaite and Paplauskiene, 2005). In a previous study, also at Stende, a significant effect of year on variation of yield of HB genotypes was also observed (Bleidere et al, 2012). Overall in this current study, grain yield, TGW, TW, starch and b-glucans in 2011 were significantly lower than in 2012.…”

The aim of the study was to evaluate the yield and grain quality (1000 kernel weight, test weight, crude protein, starch, β-glucans, total phenolic content, antiradical scavenging activity and α-tocopherol content) variation of three hulless spring barley (Hordeum vulgare L.) genotypes under different levels of N, in relation to weather characteristics. The field experiments were carried out at the State Stende Cereal Breeding Institute. Three hulless barley genotypes ‘Kornelija’; ‘ST 1165’; ST 1185’ were studied during two years (2011 and 2012) using three levels of nitrogen (N80; N80+40; N80+80) by split application at the end of the tillering stage. The effects of genotype, N treatment and genotype by N treatment interaction contribute the variation in yield and grain quality traits for hulless barley genotypes. There were considerable differences between crop years in response of hulless genotypes to top-dressing N, with significantly (P < 0.05) higher grain yield, 1000 kernel weight, test weight, starch and β-glucans in the growing season of 2012, when rainfall was optimal at the tillering and stem-elongation growth stages. In 2012, a significant (P < 0.05) response to top-dressing N was recorded for grain yield and 1000 kernel weight (at rate N120), crude protein, starch and β-glucans (at rate N160). The maximum values of total phenolic content, antiradical scavenging activity (in 2011) and -tocopherol content (in 2012) were obtained with application of 160 kg N ha-1. Hulless line ‘1185’ gave the highest grain yield, starch, α-tocopherol content and radical scavenging activity, but variety ‘Kornelija’ formed significantly higher TKW, crude protein and β-glucans content.

“…significant difference between different years within the same trial sites for the NGS trait (Table 2). Bleidere et al [38] and Dofing et al [39] studying advanced bred cultivars of spring barley reported similar results in their studies showing significant interactions for environment x cultivar in different climatic conditions. One of the reasons for the environmental effect between Kyrgyzstan and Latvia is that there are differences in day lengths.…”

Barley (Hordeum vulgare L.) is an important cereal crop around the world and is of major importance to many countries [1][2]. In terms of global acreage and production, barley is the fourth major cereal crop after wheat, rice and corn globally [3], and is regarded as one of the most tolerant crops for drought and alkaline soils, and it has the highest water-use efficiency compared to other cereal crops, but it is less tolerant to acidic soils [4][5][6][7].Cultivation conditions of barley genetic diversity are essential for adapting to future environmental changes,

“…Leistrumaite and Paplauskiene (2005) found that the grain yield and quality traits of spring barley varieties vary greatly due to growing conditions. Significant effect of year as a factor to HB grain yield was observed in previous research carried out at Stende (Bleidere et al, 2012). Bleidere et al, (2013) found significant influence of genotype and nitrogen supply to the HB yield and quality characteristics.…”

The aim of this study was to evaluate the genetic and environmental variation of yield and food quality characteristics (protein, starch, β-glucan and husk content, test weight and thousand grain weight) of covered and hulless barley genotypes in organic management conditions. Two different field experiments were carried out. In the first experiment, hulless barley genotypes 'Kornelija', 'Irbe', '1165', '1185' and the covered varieties 'Ansis' and 'Maali' were studied in two locations in Latvia and in one location in Estonia during 2014. 'Ansis', ‘Kornelija', '1165' and '1185' were included in the second experiment carried out at Stende during three sequential years (2011-2013). The effect of genotype, environment (location and year) and co-effect of these factors contributed significantly to the variation in yield and grain quality traits of the barley genotypes. As a result of experimental treatments grain yield and quality traits varied by all tested factors. There were considerable differences in impact of studied sources of variation. Grain yield was influenced more by environmental factors than by genotype. Impact of genotype was highest for husk content and test weight. Integral evaluation method was carried out for comparison of barley genotypes to identify the best ones by the lowest deviation from the desired value. The covered barley variety 'Maali' showed good adaptation to different environmental conditions, having good yield, β-glucan content and high thousand grain weight. The line '1165' and variety 'Kornelija' showed best results among hulless barley varieties
