“…The absence of a relationship between grain yield and thousand grain weight can be explained by the observation that in the last decades grain yield improvement was closely correlated to the increase of grain number per unit area both in barley (Bingham et al, 2012) and wheat (Sanchez-Garcia et al, 2012), and was not associated with the increase of grain weight (Zhou et al, 2014). Although we found that grain yield was not associated with thousand grain weight, the malting industry will continue to impose additional criteria regarding development of new cultivars with its strict quality requirements.…”

“…Modern cultivars have already achieved high values of harvest index, and further improvement of barley and wheat cannot be associated with additional harvest index increase (Foulkes et al, 2007). Therefore, Zhou et al (2014) suggested that further improvement of grain yield potential should be achieved by increasing the biomass production, while maintaining or even increasing the harvest index.…”

In the 20 th century, grain yield of winter barley has increased due to advances in both breeding and crop management practices. Knowledge about the association of agronomic traits with genetic gains in yield potential is necessary to improve future breeding programs. Therefore, we studied the variation in grain yield, spike length, heading date, thousand grain weight, hectolitre mass and plant height of two-rowed winter barley cultivars that were released between 1977 and 2010, in a 2-year field trial. Our results showed that most of the analyzed traits were significantly affected by the cultivar, year and cultivar-by-year interaction. The present study showed that grain yield was positively correlated with the year of release. The average rate of grain yield increase in Serbia was 46 kg ha -1 per year. Further, grain yield was negatively correlated with plant height and heading date. Plant height and hectolitre mass of modern cultivars showed a significant declining trend, from the oldest to the newest cultivars. An improved understanding of the changes in agronomic traits over the last 40 years of barley breeding will help to identify targets for further breeding progress and improve the genetic potential of barley.

Wheat and rice are the most important food crops in agriculture providing around 50% of all calories consumed in the human diet. While both are C3 species, the evolution and domestication of wheat and rice occurred in very different environments, resulting in diverse anatomical and metabolic adaptation. This review focuses on the current understanding of their adaptation in an agronomic context. The similarities and differences between wheat and rice are discussed, focusing on traits related to phenology, photosynthesis, assimilate partitioning, and lodging resistance, these being the main abiotic drivers of yield expression in most agro-ecosystems. Currently, there are significant knowledge gaps in the major biological processes that account not only for differential adaption among cultivars within each species, but even between the two species. By addressing what is known as well as where gaps exist in a comparative context, this review aims to highlight translational research approaches that could provide insights into the genetic improvement of both crops.

“…The absence of significant changes in plant dry matter at physiological maturity showed that the canopy traits associated with radiation use efficiency did not change significantly during the development of new cultivars (Araus et al, 2008). Accordingly, further increase in grain yield should be achieved by developing new cultivars with the higher dry matter at anthesis and maturity, while maintaining high values of the harvest index (Zhou et al, 2014).…”

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.
