“…Several investigations reported that STB resistance is either quantitative or qualitative, and the inheritance of the resistance may follow dominant, partially dominant, epistatistic, recessive, additive, and non-additive gene action (McCartney et al, 2002;Chartrain et al, 2009 be monogenic or oligogenic, and the near-complete nature of resistance follows the gene-for-gene model (Somasco et al, 1996;Arraiano, 2001;McCartney et al, 2002;Brading et al, 2002). Other authors claimed that resistance was often quantitative, polygenic and provides partial resistance to a wide variety of isolates (Jlibene et al, 1994;Simon and Cordo, 1998;Zhang et al, 2001;Chartrain et al, 2004;Arraiano and Brown, 2006). The partial resistance is durable under field conditions and is expressed as a reduction in epidemic development (Chartrain et al, 2004).…”

During the last decade 18 major resistance genes (Stb1-Stb18) to STB have been identified and mapped in the wheat genome (Arraiano et al, 2007;Goodwin, 2007;Chartrain et al, 2009;Tabib Ghaffary et al, 2011a;2011b).…”

Septoria tritici blotch, causal agent Mycosphaerella graminicola (Fuckel) J. Schröt. (anamorph: Zymoseptoria tritici Desm.), is the major foliar disease of wheat (Triticum aestivum L.) in Tunisia causing frequent epidemics on T. turgidum L. var. durum (Desf.) Bowden, and important yield and grain quality losses. To determine the inheritance of resistance to septoria, a cross was made using resistant ('Salim') and susceptible ('Karim') cultivars. Parents, and the 149 derived recombinant lines, were tested for resistance to septoria under field conditions during the 2009 and 2010 crop seasons. The inheritance of resistance to septoria was quantitative where a continuous and normal distribution (W = 0.93) was shown among segregate progenies. During 2009 and 2010 crop seasons, the mean disease severities of recombinant inbred lines (RILs) ranged from 29.1% to 41.8%, respectively, and 53% of RILs were associated with lower disease severity than the mid-parent value. The severity was significantly affected by Genotype × Year interaction (p < 0.01). Broad sense heritability was 0.55 suggesting a quantitative inheritance of resistance to M. graminicola. These results would imply that genetic resistance to STB could be attributed to additive gene effects. Thus, using identified sources of tolerance to STB in a breeding program would enhance the development of cultivars that are adapted to the prevailing isolates in field conditions.

“…Arina,Flame and TE 9111) were specifically resistant to the largest number of isolates collected in different regions (Abrinbana et al 2012). Also Chartrain et al (2004a) did not find resistance in Arina, carrying the genes Stb6 and Stb15 (Arraiano et al 2007), specific to any of the three fungal isolates used in the tests and no QTL controlling a major part of the Arina resistance was identified either, suggesting that its resistance may be dispersed and polygenic. It was shown (Keller et al 2000;Goudemand et al 2013) that partial or quantitative resistance which is isolate non-specific, polygenic and generally more durable than race specific resistance should provide a more sustainable strategy in resistance breeding.…”

“…Resistance to Zymoseptoria tritici is based on the monogenic isolate -specific Stb genes (Chartrain et al 2009;Ghaffary et al 2012) and quantitative, non-isolate-specific resistances (Chartrain et al 2004a;Goudemand et al 2013). Brading et al (2002) reported firstly that isolate-specific resistance of wheat to Septoria tritici blotch follows a doi: 10.17221/44/2015-CJGPB gene-for-gene relationship.…”

AbstractŠíp V., Chrpová J., Palicová J. (2015): Response of selected winter wheat cultivars to inoculation with different Mycosphaerella graminicola isolates. Czech J. Genet. Plant Breed., 51: 86-95.Five winter wheat cultivars, differing in resistance to Septoria tritici blotch (STB), were spray inoculated under field conditions for two years and at two locations with nine Mycosphaerella graminicola isolates and a mixture of isolates that were obtained from different regions of the Czech Republic. Main aims of this study were (i) to compare isolate, host cultivar and environmental effects on five traits indicative of STB severity and (ii) to analyse pathogen aggressiveness and host-pathogen relations for improving evaluation of cultivar resistance. ANOVA showed in all traits, except the reduction in 1000 grain weight, significant isolate effects. However, the effects of isolate and genotype by isolate interactions were much lower (2.3-4%) than cultivar (19.1-53.7%) and environmental (11.9-58.6%) effects. Cultivar resistance to the disease limited much the loss in grain weight per spike to a halve, from 34.7% in the susceptible Bakfis to 17.3% in the resistant Arina. Visual scoring of symptoms in the middle and at the end of disease development (performed on the 1-9 scale), reflecting the disease progress and infected leaf area, showed the highest cultivar effect (54%) and could be recommended for evaluation of cultivar resistance in breeding practice. All examined traits were significantly interrelated, but significant differences between all the five cultivars were only detected after examination of the % coverage of flag leaves with lesions bearing pycnidia. Resistance in the cultivar Arina was detected by all isolates and the isolate mixture. In spite of significant differences in classification of resistances in the cultivars Bohemia and Mulan after inoculation with one isolate (1081), specific interactions between cultivars and isolates collected in this Central European region are rare. The study leads to a conclusion that investigation into stability of STB resistance across a wide range of environments is more valuable for breeding purposes than the study of cultivar response to different isolates. Combination of important isolate properties in a mixture of isolates is stressed as well

“…Breeding for septoria leaf blotch disease resistance has lagged due to the scarcity of resistant germplasm and an inadequate understanding of hostpathogen relationships. In spite of recent achievements in the identification of resistance to septoria leaf blotch in bread wheat (Chartrain et al 2004), limited progress has been achieved in the case of durum wheat (Yahyaoui et al 2000).…”

Genomic Constitution and Expression of Disease Resistance in Agropyron cristatum * Durum Wheat Derivatives

et al. 2007

Septoria leaf blotch, powdery mildew and yellow and brown rusts are major wheat diseases characterized by a worldwide distribution. The level of genetic resistance against these diseases is low in durum wheat (Triticum turgidum) germplasm, while some wheat relatives, such as crested wheatgrass (Agropyron cristatum), are resistant. In an attempt to incorporate resistance genes into durum wheat, crosses were carried out between durum wheat and a fertile allotetraploid (2n = 4x = 28; DDPP) previously obtained from a cross between diploid wheat (T. tauschii) and crested wheatgrass (A. cristatum). The plants were backcrossed twice to durum wheat and studied for their reaction to the diseases. The genomic constitution of all the backcross derivatives from these crosses were analyzed by fluorescence in situ hybridization (FISH) using both total genomic DNA of A. cristatum and the pAs1 repetitive DNA sequence isolated from T. tauschii. All of them retained chromosomes or chromosome segments of A. cristatum. All the analyzed plants were immune to septoria leaf blotch and powdery mildew and showed a high level of resistance to yellow and brown rusts.
