Das Projekt "Establishing of improved cultivars of high yielding food crops by means of conventional in vitro-breeding, mutagenesis and selection techniques (non-GMO)" wird vom Umweltbundesamt gefördert und von Phytotech Foundation durchgeführt. In previous projects of the EC and Switzerland a non-GMO approach of conventional in-vitro breeding and mutagenesis was used to introduce a good number of new genotype of crop plants with significantly enhanced properties for metal accumulation, extraction and exclusion, for improving of the effieciency of phytoextraction technique for cleaning of contaminated soil. Within COST Action 859 most efficient genotypes of sunflower, Brassica and tobacco and specific cultivation methods will carefully be assessed and comparative field experiments in Switzerland and Belgium will be continued with the aim to optimise and validate the 'improved phytoextraction technique' and to bring this sustainable remediation procedure towards a practical use.
