Sensitivity of European wheat to extreme weather

Popis výsledku v původním jazyce

The frequency and intensity of extreme weather is increasing concomitant with changes in the global climate change. Although wheat is the most important food crop in Europe, there is currently no comprehensive empirical information available regarding the sensitivity of European wheat to extreme weather. In this study, we assessed the sensitivity of European wheat yields to extreme weather related to phenology (sowing, heading) in cultivar trials across Europe (latitudes 37.21o to 61.34o and longitudes -6.02o to 26.24o) during the period 1991-2014. All the observed agro-climatic extremes (GREATER-THAN OR EQUAL TO31. oC, GREATER-THAN OR EQUAL TO35. oC, or drought around heading; GREATER-THAN OR EQUAL TO35. oC from heading to maturity; excessive rainfall; heavy rainfall and low global radiation) led to marked yield penalties in a selected set of European cultivars, whereas few cultivars were found to with no yield penalty in such conditions. There were no European wheat cultivars that responded positively (+10%) to drought after sowing, or frost during winter (-15. oC and -20. oC). Positive responses to extremes were often shown by cultivars associated with specific regions, such as good performance under high temperatures by southern-origin cultivars. Consequently, a major future breeding challenge will be to evaluate the potential of combining such cultivar properties with other properties required under different growing conditions with, for example, long day conditions at higher latitudes, when the intensity and frequency of extremes rapidly increase.
