| Popis: | In Europe, durum wheat is traditionally grown primarily in the Mediterranean region. A question arises as to whether now, in a situation of global climate change, the conditions for durum wheat might be more favourable also in countries with temperate continental climate. Field trials at a location in the south-eastern part of the Czech Republic with a typical European continental climate were established in four harvest years (2011 – 2014). Yield, quality and deoxynivalenol content were evaluated and the impact of year and variety was studied. The best quality was achieved in 2013, when 4 of 5 varieties met all the quality requirements for durum wheat according to Commission Regulation (EU) No. 1272 / 2009. The most frequent reason for unsatisfactory quality was loss of vitreousness and low falling number. In 2012, three varieties froze, and this year was therefore excluded from evaluation. Yield varied between 7.6 t ha−1 in 2013 to 10.9 t ha−1 in 2014 and it was in a negative, statistically significant relationship with most of qualitative traits, particularly with vitreousness (r = − 0.72). The strongest correlation between qualitative traits was found between vitreousness and thousand kernel weight (r = − 0.73) and vitreousness and test weight (r = 0.70). |
