Název v původním jazyce

Effective use of water by wheat varieties with different root system sizes in rain-fed experiments in Central Europe

Popis výsledku v původním jazyce

Effective use of water (EUW) was evaluated along with grain yield in the same environment over different years and locations. The root system sizes of sets of winter wheat varieties (20, 20, 20 and 18 varieties in 2007, 2008, 2009 and 2010, respectively)were evaluated by measuring thein electric capacity. The RSS results were compared with the yield and grain quality in official variety trials at 20, 22, 23 and 23 stations in 2007, 2008, 2009 and 2010, respectively. All varieties were tested under twoconditions with low and high inputs, and in some years they were also tested after late sowing and after unsuitable forecrops at a few stations. The RSS was mostly controlled by the location; the varieties differed significantly, explaining 2.6-15.6% ofthe variation in RSS, while 1.7-3.9% of the total variation was unexplained. In 2007, a dry year, the RSS was significantly correlated with yield in both variants (r2 = 0.285* and 0.284*, respectively) and with yield of starch (r2 = 0.248
