Abstract

Investigations on the stem rast resistance of wheat varieties and lines carrying various stem rust resistance genes or gene combinations have been underway for several decades in the artificially infected nursery in Martonvásár. The data recorded between 1994 and 1999 are used in this paper to demonstrate the efficiency of the different stem rast resistance genes and the extent to which cultivated varieties bearing the Sr31 gene become infected. The Sr36 gene provided complete protection against the rast population used in the tests, while genotypes bearing the resistance genes Sr6, Sr7a, Sr 27 and SrGr suffered less than 10% infection. The efficiency of the Sr31 gene was influenced to a considerable extent by the genetic background of the wheat varieties, but further investigations will be required to clarify the reason for these differences.
