Dough mixing properties are important in determining wheat processing and end-use quality. The Reomixer is a mixograph type device which provides mixing curves, described in detail by a total of 17 parameters. We analyzed the Reomixer mixing parameters of 26 breeding lines grown in 2007, in four contrasting environments (with and without Nitrogen fertilization, under water stress or irrigated). Using these data, we attempted to condense the information by identifying the most suitable parameters for use in a breeding program. We used the following criteria: high reproducibility (minimum coefficient of variation among repetitions), high genotype influence (i.e. high heritability), larger amount of information about overall variation of the other mixing parameters and complementarity of information (low correlation with other selected parameters). Mixing parameters varied widely for all criteria and no one parameter was best for all of them. Based on average performance we selected: “initial slope”, “peak time”, “peak height”, “end width” and “breakdown”, as having better ranking for the first three criteria and being less correlated between themselves than other mixing parameters. The five selected parameters cover all phases of dough development and describe all basic rheological aspects of mixing properties.

The integration of conventional plant breeding and plant transformation is necessitated by the fact that, prior to the gene technological phase, traditional breeding methods have to be used to develop agronomically valuable homozygous genotypes which can then be modified for a gene or genome segment by means of gene manipulation techniques. Once the genotype selected by means of conventional breeding has been transformed, traditional methods are again used to examine the agronomic properties of the lines developed from the transgenic plant and the stability of the transgenic variety, following the DUS criteria elaborated by UPOV. The seed production of genetically modified plant varieties must be safe and economical and the cultivation of the variety should contribute to the sustainable development of up-to-date crop production.
