Responses of winter wheat (Triticum aestivum L.) to drought

Popis výsledku v původním jazyce

Six winter and one facultative wheat varieties were observed at two different localities Obora and drier Písky in Žabčice, South Moravia, during growing season 2019/2020. The effect of drought was observed on ear formation and yield components of chosen varieties. Drought affected the ear formation e.g. number of fertile spikelets per ear, number of fertile florets per ear, number of grains per ear and the yield components such as number of fertile tillers and thousand grain weight. All these traits were generally lower at the plants grown in drier location Písky. The most sensitive varieties to drought with the highest differences between yields of these two localities were Bohemia and Balitus, on the contrary, the least sensitive varieties were IS Conditor and Tybalt. Timing of drought stress led to the reduction of the yield components and the yield itself. The weather played a crucial role and in the year 2020, precipitation came during flowering time which was beneficial for later varieties. The recommendation to sow early varieties on dry locality is not always valid, especially in the conditions of Czech Republic where drought is unpredictable.
