Abstract:
The worldwide climate change is influencing agriculture in Central Europe. The extreme weather conditions like drought and heat often result in poor crop yields. In Austria it is especially the Pannonic region which suffers from drought damages on crops. Due to this background a research project has been set up in October 2009. A field experiment arranged in a randomized lattice design with three replications was set up at three locations in the East of Austria. At all sites a core set of 25 winter wheat varieties and a supplemental set with 72 genotypes was studied. The objective of this master thesis was to test and evaluate the novel selection criteria (chlorophyll content - SPD, canopy temperature - OTE, stomatal conductance - STO, osmotic potential - OSP and electrical capacitance of roots - EKA) and to determine their correlations to drought stress indicators, growth stages, plant morphology, yield and quality parameters. Genotype variability (p ≤ 0.05) was noticed for SPD, OTE, STO and OSP. SPD seem to be an effective selection criterion whereas OTE, STO and OSP were considered as critical traits. Due to the fact that EKA showed a non significant genotype effect and high variations within the replications of one plot, it has to be seen as a critical selection criterion too. Regarding the correlations it was determined that in the core set no associations among the novel selection criteria were found. Interactions (p ≤ 0.05 and p ≤ 0.01) were shown between the novel selection criteria and the stress indicators, the growth stages, the plant morphology, the yield and the quality parameters. Further correlations were noticed between the stress indicators and the growth stages, the plant morphology, the yield and the quality parameters. The yield and quality parameters were significantly associated with the growth stages and plant morphology.
