Identification of Powdery Mildew Blumeria graminis f. sp. tritici Resistance Genes in Selected Wheat Varieties and Development of Multiplex PCR

“…However, the results are doubtful, because the authors indicated that the presence of the Pm6 gene was indicated by a product of 135 bp, which is contrary to the source methodology. Similar studies were also conducted by Tomkowiak et al [39], who identified a product of 230 bp in all analyzed varieties and lines.…”

“…The latter variety may be a good source of powdery mildew resistance, because, the analyses showed that it contained all the analyzed genes, i.e., Pm2, Pm3, Pm4b and Pm6. According to literature data, Kredo might be an equally useful variety, in which Huang and Roder [11] identified the Pm3a gene, and Tomkowiak et al [39] showed the presence of the Pm2, Pm4b and Pm6 genes.…”

“…A 241-bp marker product appeared only in 3 out of 7 tested varieties: Assosan, Atomic and Sparta. Tomkowiak et al [39] also analyzed, among others, Assosan and Atomic varieties for the presence of the Pm4b gene using the STS_241 marker and did not show the presence of the gene in these varieties. Yi et al [31], Hao et al [20] and Tomkowiak et al [39] considered the non-analyzed VPM line as a reliable source of the Pm4b gene.…”
