“…The interest of the breeding studies was mainly related to the formation of high and stable grain yield (Petrović et al, 2013;Banjac et al, 2015), and less attention was paid to crop development and growth, especially during the period prior to anthesis. As previously reported (Pržilj and Momčilović, 2002;Pržulj and Momčilović, 2011), pre-anthesis crop development significantly affects the potential grain yield. For example, leaf and spikelet primordia are formed during the period from emergence to stem elongation, while the number of fertile stems and florets is determined during stem elongation period (Slafer, 2003).…”

Information about dry matter accumulation is of great importance for further increase of barley yield. Various nonlinear and linear curves have been used to describe vegetative and reproductive growth for a number of agricultural crops. Although dry matter accumulation is an important parameter of crop growth, knowledge about biomass production under agro-ecological conditions of the Pannonian Plain are scarce. This study was undertaken to analyze the pattern of dry matter accumulation in two-rowed winter barley cultivars and changes in biological parameters of the logistic curve under different sowing dates and growing seasons. Therefore, trials with two late cultivars of two-rowed winter barley were conducted in two growing seasons and four sowing dates. Results from this study indicate that dry matter accumulation in both growing seasons followed a typical sigmoid shape. Delayed sowing led to a significant decrease in the maximum value of plant dry weight, the termal time needed to reach maximum value and duration of exponential growth, and increase in maximum crop growth rate. These results indicate that apart from appropriate cultivar selection, early barley sowing is also important to achieve high plant dry matters one of the main determinants of grain yield.

“…Compared to other cereals, barley is well adapted to drought [64], but the lack of accessible water in the grain-filling period strikes photosynthesis. This condition results in reduced accumulation of biomass, more abortive flowers and grains, a decrease in the mass of individual grains [65,66], acceleration of the grain-filling period [67], and a reduction of grain yield in two-row barleys by 28.8% [68]. High values of precipitation cause waterlogging and lodging of the stem.…”

Genotype by environment interaction (GEI) is a complex problem that complicates the barley selection and breeding process. The knowledge of the relationship between cereal phenology and climatic data is important for understanding GEI and the physiological pathways responsible for the interaction effect. The grain yield of twenty winter barley genotypes in six environments was observed. Factors influencing the variability were analyzed using a linear mixed model. The partial least squares regression (PLSR) model was applied to determine the most relevant environmental variables in certain stages of development that explained GEI effects. Biplot with environmental variables explained 43.7% of the GEI. The barley was generally the most sensitive to the environmental conditions (relative humidity, maximum temperature and its variation, sun hours, and precipitation) during the anthesis and filling stage (May) which caused GEI. Temperature variables did not show significance only in the vegetative phase. Different genotypes responded differently to environmental factors. Genotypes NS-525, NS-589, and J-103 were highlighted as widely adaptable, and Zaječar was a suitable and reliable location for yield testing. The GEI information presented in this paper can be useful in traditional plant breeding and future breeding programs through molecular research of crop developmental genes and examination of physiological processes in two-row barley.

“…The main environmental factors determining agronomic properties and grain quality of spring barley are temperature, water and nutrition supplies (ZHANG et al, 2006;PETTERSSON and ECKERSTEN, 2007). Barley yield and grain characteristics are determined in both periods from planting to anthesis (VP) and grain filling period (GFP) (SLAFER et al, 2005;PRŽULJ and MOMČILOVIĆ, 2011). Heat stress in VP and GFP can significantly decrease grain yield and quality of barley (CATTIVELLI et al, 2008).…”

Environmental conditions in the Pannonian zone can be characterized with moderate high temperature and partially water deficit during grain filling of spring barley, although low temperature and water deficit are possible also in period till anthesis. This study was conducted to evaluate the variation of the duration of the period from emergence to anthesis (VP), duration of grain filling period (GFP), plant height (PH), spikes number m-2 (SN), grains number spike-1 (GN), thousand grains weight (GW) and yield (YIL) in spring two-rowed barley in conditions of the Pannonian zone. All three factors; genotype, environment and the interaction GxY affected the studied traits. Average VP was 777 GDD, GFP 782 GDD, PH 78 cm, SN 523, GN 28.2, GW 43.2 g and YIL 6.26 t ha-1. Variation across varieties was higher than across growing seasons. Heritability varied from 0.66 for YIL to 0.94 for VP and GFP. This study confirmed that a sufficiently large genetic variability must be base for selecting appropriate varieties for the Pannonian zone conditions. In order to determine high yielding and quality barley extensive research in relation to breeding, variety choice for production and growing practice must be done
