Název v původním jazyce

Improved root system for better wheat drought tolerance

Popis výsledku v původním jazyce

Larger root system allows better use of water and nutrients from the soil as has been already proven several times. Deep-rooting varieties can be successful on soils with higher levels of groundwater in dry years. It is necessary to precisely identify suitable phenotypes for deliberate plant breeding e.g. for tolerance to drought. The aim of the research was to analyze the measured data on the size of the root system in three phenological stages in the years 2015-2017, to evaluate the relationship between the root system size (RSS) and the yield of the grain. The root system size and winter wheat grain yield were evaluated in the field experiment at a dry locality in Branišovice (South Moravia, Czech Republic). The properties of the root system of various genotypes in years with different meteorological conditions were identified. The correlation analysis of the relationships between RSS and grain yield was significant particularly in 2015. Early genotypes created a larger root system at the time of RSS measurement which was subsequently reflected by an increase in grain yield.
