“…These results were in agreement with previous studies [ 32 , 33 , 34 ] where the variation in the environmental and soil conditions was found to contribute to differences in morphological traits such as grain yield, number of grains/spike, leaf area, chlorophyll content, plant height, and grain weight for the same genotypes. Additionally, the third environment (E3) was more suitable for most of the barley genotypes due to exposing the genotypes to favorable growth conditions, which resulted in the better overall performance of the genotypes under this environment [ 35 , 36 ]. The results of barley resistance to leaf rust, net blotch, and powdery mildew diseases indicated a correlation between these diseases and the eco-geographical characteristics of the locations used, including average annual rainfall, altitude, and average annual temperature [ 37 , 38 ].…”

In recent years, barley has attracted more interest as a food and feed source because of its high soluble dietary fiber and β-glucan content compared with other small grains. Twenty-five barley genotypes (20 imported genotypes and five check cultivars) were grown in three environments for two successive seasons: 2015/2016 and 2016/2017. The first environment was in El-Nubaria, Alexandria, Egypt during 2015/2016, while the second and third environments were in El-Bostan, Elbhera, Egypt during 2015/2016 and 2016/2017. The experiments were conducted in a randomized complete block design with the three replicates. The primary objectives of the current study were to evaluate the performance of 20 imported barley genotypes under several environmental conditions. The imported materials were superior to the local commercial cultivars for several traits, including grain yield. Therefore, the superior genotypes will be further evaluated and used in barley breeding programs. Our future work will focus on creating several crosses among the selected superior genotypes to improve yield and other important traits, while applying marker-assisted selection.

“…To interpret the experimental data of multi-environment trials, it is necessary to use the most appropriate statistical models (Eeuwijk et al, 2016). To evaluate barley yield stability a number of parametric and non-parametric stability indices have been used (Dimova et al, 2012;Verma, 2017). However, comprehensive genotypeenvironment data analysis must cover not only genotype evaluation, but two other important aspects: mega-environment analysis and test-environment evaluation (Yan and Tinker, 2006).…”

In modern conditions it is necessary to create varieties of spring barley with combination of high grain yield and stability. For this purpose, multienvironment trials of nine advanced breeding lines and the standard variety Vzirets were carried out in three different ecological zones in Ukraine: Central Forest-Steppe, Polissia and Northern Steppe. High yield variability of spring barley breeding lines has been established. The ANOVA revealed reliable contributions from all three source of the variation: genotype, environment and genotype-environment interaction. The part of influence for environment was the highest -90.42 %. A set of statistical indices (regression coefficient (b i ), deviation mean squares (S 2 d i ), variety superiority measure (P i ), nonparametric stability indices (S i (1) and S i (2) ), homeostaticity (Hom i ), breeding value (Sc i )) and GGE biplot were used to interpret the multi-environment trial data. The applied statistical indices in different ways characterized the investigated barley breeding lines. Some indices estimated the stability only, without considering yield level (S 2 d i, S i (2) ). Other indices were related with the mean yield (P i ), with the maximum (b i ) or minimum (S i (1) , Hom i , Sc i ) its value. The combination of statistical indices and graphic model was effective for comprehensive evaluation of the genotype-environment data from multi-environment trials. This approach allows identify the best of the best breeding lines at the final stage of breeding work. The breeding lines Deficiens 5005, Nutans 4855, Nutans 4941 and Nutans 4890 have been submitted to the State Strain Testing of Ukraine as new varieties MIP Visnyk, MIP Ekspert, MIP Myroslav, MIP Vdiachnyi, respectively.

“…The main objective of any wheat breeding program is to create varieties with high yield potential, possessing a complex of biological and agricultural quality, resistant to biotic and abiotic stress factors and suitable for low input (Rachovska et al, 2003;Dimova et al, 2006;Ivanova and Tzenov, 2009b;Tzenov et al, 2009;Bozhanova et al, 2009a). By approaching the limits of biological productivity and as a result of global climate change, the need for new sources material to create new varieties that meet the climate change has greatly increased.…”

Fifteen winter bread wheat cultivars from Romania and Serbia were evaluated with regard to their tolerance to osmotic stress. Evaluation was made by applying the indirect physiological method, recognizing the growth depression seedling, cultivated in solution with increased osmotic pressure (Atm). Water deficit in most of the genotypes suppresses to a great extent the growth of roots compared to that of the shoot. The average coefficient of root growth depression was 55.77% during the moderate osmotic stress trial and 55.83 % during the strong osmotic stress trial, while with shoots the percentage was 35.76 % and 50.12 %, respectively. The average root length / shoot length ratio (R/Sh ratio) for all genotypes in the control was 1.70; in the 0.5 M and 1 M sample solution sucrose it was 1.14 and 1.55, respectively. In genotypes most tolerant to osmotic stress as Renesansa, Dragana, Izvor and Faur the root/ shoot length ratio is decreased in the highest degree. It was established there is negative regression dependence between the growth of the root/shoot and the solution with increase of osmotic pressure. The equations showed the strong limitation role of osmotic pressure for the growth of the seedling. The results of this study showed that the varieties Renesansa, Dragana, Izvor and Faur had the best ability of osmotic regulation.
