The effect of tillage systems (TS) on wheat quality traits including grain yield, thousand-kernels weight, hectoliter mass, flour extraction rate and flour rheological properties were evaluated. Five different TS were compared in winter wheat (Triticum aestivum L.) production on one experimental field (chernosem) located in the Baranya region, north-eastern Croatia from 1998 to 2001. Tillage systems included conventional tillage (CT), disc harrowing, fine till (DHF), soil loosening (SL) + disc harrowing (DH), disc harrowing, coarse till (DHC) and no-tillage (NT). The most stable grain yield was obtained by DHF and CT in all three experimental years. There was no striking regularity with regard to applied TS and hectoliter mass and thousand-kernels weight. The biggest difference of hectoliter mass was determined between CT and NT. TS had significant influence on the flour extraction rate in all three experimental years. The influence of TS on farinographic parameters was significant for all three experimental years for the quality number. Quality number was greater under CT than under other TS. Tillage effect on extensographic and amylographic parameters in the 3-year average did not show statistically significant differences. To sum up, since disc harrowing (DHF) and (DHC) followed by soil loosening with chisel produced equal grain yield and wheat quality parameters were slightly better than conventional tillage, these systems could be presented as an even handed replacement for ploughing.

A primary objective of the wheat breeder is to develop populations with optimum combinations of genes controlling key traits. As more is known about the control of specific traits by specific genes, more emphasis can be placed on the use of markers for specific genes, or specific alleles of genes, in wheat breeding. Markers that define specific genes are known as “perfect” markers as they are 100% linked to a gene controlling some significant component of the variability in the trait of interest. Perfect markers are of interest not only because they provide the breeder with a direct means of selecting for a trait, but also because they are directly linked to the mechanism underpinning the trait and are therefore highly valuable from a research perspective. In this paper, we discuss the range of perfect markers available for use in breeding and research in wheat quality. The choice of genes selected, the types of polymorphisms in the genes being targeted, the marker systems used to reveal the polymorphism, and strategies for the implementation of the markers in breeding and research are discussed. In addition, we discuss the future potential for the development of perfect markers given the rapid developments in cereal science and genomics.

This paper aims to give an overview on the different aspects of QTL analysis of quality traits of wheat through the brief introduction of molecular genetics, cereal chemistry and the statistical methods developed and applied recently in this area. Some examples are also provided, based on the author's research activity carried out in the National Wheat Molecular Marker Program (NWMMP) established in Australia in 1996.
