| Sumario: | Chromosomal location of resistance to two virulent Argentinean isolatesof<em>Septoria tritici</em>was studied in two wheat (<em>Triticum aestivum</em>L.) cultivars (Cappelle-Desprez & Cheyenne), a synthetic hexaploid(Synthetic 6x) and<em>Triticum spelta</em>in seedlings. Substitution lines of these(resistant or moderately resistant) genotypes into (susceptible)<em>ChineseSpring</em>were selected from a previous screening. For Synthetic 6x,resistance was clearly located in chromosome 7D. Chinese Spring with the7D chromosome substituted by Synthetic 6x showed almost completeresistance, similar to the level of Synthetic 6x. For the substitutions withCappelle-Desprez, Cheyenne, and<em>T.spelta</em>there were no lines with abehaviour similar to the resistant parent. However, some substitutions weremore resistant than the susceptible parent suggesting that severalchromosomes could be involved in the resistance of these genotypes toSeptoria leaf blotch. |
