Genetic Background of the Resistance against Parasitic Nematodes in Wheat

Resumo

The state of the art in research on the genes responsible for the resistance of soft wheat Triticum aestivum L. against cereal cyst nematode Heterodera avenae and root lesion nematode Pratylenchus neglectus and the use of these genes in plant breeding programs are described. Most genes responsible for the resistance to these plant pathogens are listed and their chromosomal localization and resistance specificity are described. The sources of resistance genes widely used to control the cereal cyst nematode are presented. The alternative methods for transferring nematode resistance genes into wheat are outlined.
