    Genetics of resistance to Puccinia graminis tritici in ‘Chris’ and ‘W3746’ wheats (1987)

    Notes: Summary ‘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.

    Notes: Summary Seven genes, viz. Sr5, Sr6, Sr7a, Sr8a, Sr9b, Sr12 and Sr17 were associated with seedling resistance to Puccinia graminis tritici in Kenya Plume wheat. The predominant field cultures were avirulent on seedlings with Sr7a, but possessed virulence for the other six genes. However, Sr7a did not confer adult-plant resistance when present on its own. Adult-plant resistance was attributed to Sr2 and possibly also to the interaction of Sr7a and Sr12. Two genes, Lr13 and Lr14a, were identified in seedling tests with various cultures of Puccinia recondita tritici. Lr13 conferred adult-plant resistance to the predominant field strains. Genetic recombination between Lr13 and Sr9b was estimated at 17.6±3.1%.
