‘Chris’ wheat possessed genes Sr5, Sr7a, Sr8a, Sr9g and Sr12. ‘W3746’, derived from the cross ‘Chris’/‘Baart’, possessed Sr7a and Sr12. The response conferred by Sr7a was influenced by the genetic background. Although Sr7a or Sr12 alone conferred no observable resistance upon adult plants, the adult resistances of ‘Chris’ and ‘W3746’ to predominant pathotypes appeared to be associated with the interaction of Sr7a and Sr12, or genes at closely linked loci.
