“…The production parameters were found to be strongly affected by the climate treatments as displayed in Table 2, and differences between cultivar responses were prominent as reported by Ingvordsen et al (2015). Elevated temperature decreased overall grain yield (55.8 %), number of grains and also aboveground vegetative biomass and HI.…”

Future barley cultivars will have to produce under the constraints of higher temperature in combination with increased concentrations of atmospheric carbon dioxide and ozone as a consequence of climate change. A diverse set of 167 spring barley genotypes was cultivated under elevated levels of temperature (?5°C) and [CO 2 ] (700 ppm) as single factors and in combination as well as under elevated [O 3 ] (100-150 ppb) as single factor. The setting in general resembled changes projected by IPCC (AR5) to take place at the end of this century. A genome-wide association study (GWAS) was performed to identify markers for increased primary production under climate change conditions and reveal possible genes of interest. Phenotyped traits included grain yield, number of grains, number of ears per plant, aboveground vegetative biomass, harvest index and stability of the production parameters over the five applied treatments. The GWAS encompassed 7864 SNP markers (Illumina iselect), a compressed mixed linear model with the GAPIT package, and conservative validation of markers. A total of 60 marker-trait associations [-log 10 (P value) 2.97-5.58] were identified, e.g. grain yield under elevated temperature on barley chromosome 2H, static stability of grain yield on 7H, sites for exploitation of elevated [CO 2 ] on 4H Electronic supplementary material The online version of this article (

“…The details of the experimental set ups are provided in (Ingvordsen, 2014) and Ingvordsen et al (2015). For the LCA study, we considered a subset of data, including 13 cultivars listed in Table 2 (Ingvordsen et al, 2015). Among these cultivars we further selected the five cultivars with the highest grain yield under the double-factor treatment, and considered them as a separate group, as reported in Table 2.…”

The paper has two main objectives: (i) to assess the eco-efficiency of spring barley cultivation for malting in Denmark in a future changed climate (700 ppm [CO 2 ] and +5ºC) through Life Cycle Assessment (LCA) and (ii) to compare alternative future cultivation scenarios, both excluding and including earlier sowing and cultivar selection as measures of adaptation to a changed climate. A baseline scenario describing the current spring barley cultivation in Denmark was defined, and the expected main deviations were identified (differences in pesticide treatment index, modifications in nitrate leaching and change in crop yield). The main input data originate from experiments, where spring barley cultivars were cultivated in a climate phytotron under controlled and manipulated treatments. Effects of changed climate on both crop productivity and crop quality were represented, as well as impacts of predicted extreme events, simulated through a long heat-wave. LCA results showed that the changed climatic conditions will likely increase the negative impacts on the environment from Danish spring barley cultivation, since all environmental impact categories experienced increased impact for all investigated scenarios, except under the very optimistic assumption that the pace of yield improvement by breeding in the future will be the same as it was in the last decades. The main driver of the increased environmental impact was identified as the reduction in crop yield. Therefore, potential adaptation strategies should mainly focus on maintaining or improving crop productivity. The LCA also showed that selection of proper cultivars for future climate conditions including the challenge from extreme events is one of the most effective ways to reduce future environmental impacts of spring barley. Finally, if yield measurements are based on relative protein content, the negative effects of the future climate seem to be reduced.

Growth performance, productivity and diseases susceptibility of barley varieties in Slovenia within the Cobra project’s site comparison

Different plant genotypes react differently in different climates. A field experiment was carried out to estimate the growth performance, productivity and diseases susceptibility of spring barley varieties in the Slovenian climate. We received some varieties, mainly of Nordic origin, from the Technical University of Denmark, a COBRA project partner, which were previously tested in estimated future climate in RERAF phytotron. Varieties of the highest grain yield (3,993 kg ha -1 in 'Evergreen' to 5,146 kg ha -1 in 'Sebastian') were rather shorter (58.7 cm to 67.1 cm) and mostly had the highest specific grain weight (54.3 to 58.6 kg 100 L -1 ) and 1000-kernel weight (30.2 to 37.1 g). They developed 1,561 to 2,532 tillers m -2 and 515 to 840 ears m -2 and reached a heading stage between 13 th and 25 th of May. The tested varieties seem rather insusceptible to most common diseases, but susceptible to cereal leaf beetle attacks.
