The objective of the study was to provide information about the occurrence and distribution of resistance genes in wheat cultivars, including old cultivars, land races and advanced breeding lines grown in China. Ninety?four accessions were analysed with a set of 11 differential powdery mildew isolates. Forty?four cultivars did not possess any major mildew resistance genes. Thirty cultivars revealed the response pattern of individual resistance genes. The most frequently encountered gene was Pm8, which occurred singly in 11 cultivars, combined either with Pm4a in three cultivars or with Pm4b in another three cultivars. However, 12 cultivars possessing the wheat?rye translocated chromosome pair T1BL?1RS did not express Pm8. Gene Pm2 was found in four cultivars and in combination with Pm6 in one cultivar. Genes Pm4a and Pm4b were observed in four and five cultivars, respectively. Another six cultivars carried Pm5. A gene combination of Pm2+Pm4b+Pm6 was found in one cultivar. Twelve cultivars and breeding lines exhibited a response pattern that could not be assigned to resistance genes or gene combinations present in the differential cultivars. Five out of these 12 cultivars/lines showed resistance to all the isolates tested. There is an urgent need to search for novel sources of mildew resistance in order to sustain resistance to existing and emerging powdery mildew pathogens. |
