Response to stripe rust (Puccinia striiformis Westend. f. sp tritici) and its coincidence with leaf rust resistance in hexaploid introgressive triticale lines with Triticum monococcum genes



Response to stripe rust (Puccinia striiformis Westend. f. sp tritici) and its coincidence with leaf rust resistance in hexaploid introgressive triticale lines with Triticum monococcum genes



Journal of Applied Genetics 50(3): 205-211



Triticale introgressive lines were developed by incorporating diploid wheat (Triticum monococcum [TM16]) genes into the hexaploid triticale genotype LT522/6. The synthetic allotetraploid T monococcum cereale (A(m)A(m)RR) was used as a bridging form to introduce the genes. A group of 43 introgressive lines, parental stocks and a check cultivar were inoculated at the seedling stage (in the greenhouse) and at the adult plant stage (in the field) with four pathotypes of Puccinia striiformis f. sp. tritici to determine if the stripe rust resistance was derived from TM16 and to analyze the expression of the diploid wheat gene(s) at the hexaploid level. At the seedling stage, 14 triticale introgressive lines expressed resistance to some of the used pathotypes, showing introduction of a genetic material from the T monococcum genome. Among them, 7 lines were resistant to all four stripe rust pathotypes applied at this stage. In the field, adult plant resistance and percentage of infected leaf area were scored and transformed into the coefficient of infection. Plant response to stripe rust was compatible at these two developmental stages with a high statistical probability showing the genetic dependence on the same genetic background. Also observed was a full concordance of the adult plant resistance to stripe rust with previously assessed resistance to leaf rust, as well as the highly significant linkage of the resistance to the both diseases at the seedling stage in the set of the tested introgression lines. This result strongly suggests that T monococcum genes responsible for these characters are located in proximity.
