“…ventricosa segment in which the linkage has been broken, or to another genetic source that promotes yield potential. Previous reports Lind 1999) have shown that cultivars carrying Pch1 with Cappelle Desprez (Pch2 and Q.Pch.jic-5A) in their pedigrees, such as Rendezvous, have enhanced adult plant resistance. However, those varieties are not widely used in breeding as a result of their relatively low yield in spite of the absence of the disease.…”

Eyespot can reduce yields, even up to 50%. There are four genetically characterized resistances in wheat varieties, controlled by: (1) the Pch1 gene, transferred from Aegilops ventricosa; (2) the Pch2 gene, originating from wheat variety Capelle Desprez; (3) the Q.Pch.jic-5A genes was compared with resistance conferred by Pch1 or Q.Pch.jic-5A alone. We found significant differences between infection scores evaluated in resistant lines carrying Pch1 and Q.Pch.jic-5A alone, while no differences in terms of the level of resistance expression were detected between Pch1 alone and Pch1 + Q.Pch.jic-5A, and between wheat lines carrying Pch1 and Pch2 alone. Moreover, we demonstrated that the Pch1 gene, together with an Ae. ventricosa segment, caused statistically significant yield losses, both as a single eyespot resistance source or in a combination with Q.Pch.jic-5A. Yield scores showed that wheat lines with Q.Pch.jic-5A had the highest yields, similar to the yielding potential of Pch2-bearing lines and control varieties.

“…Renan possesses powdery mildew resistance gene Pm4b. It also has Pch1 for eyespot resistance (Lind 1999). Resistance to Fusarium head blight was described by Bai and Shaner (2004) and observed also by Chrpová (personal communication).…”

Our field experiments confirmed the leaf rust resistance of cv. Renan in the Czech Republic. Whereas the leaf rust resistance gene Lr37 possessed by Renan is generally effective as late as at the adult plant stage, we found one leaf rust isolate that caused resistant to moderately resistant reactions on NIL Lr37 as well as on the cv. Renan already at the seedling stage. This isolate was used in the study of genetics of the leaf rust resistance of cv. Renan in greenhouse experiments. The presence of translocation from Aegilops ventricosa carrying the cluster of rust resistance genes Lr37, Sr38 and Yr17 was also determined by a PCR molecular marker. All experiments confirmed the presence of Lr37 gene in cv. Renan. The presence of Lr14a, postulated earlier, could not be verified. The resistance of cv. Renan in the field was slightly higher than that of the line Tc/8//VPM1 possessing Lr37, which may indicate a more complex genetic base of leaf rust resistance in the cv. Renan. In the progeny of the cross Boka/Renan leaf rust resistance gene Lr37 behaved as a recessive or partially dominant gene, stem rust resistance gene Sr38 as a dominant gene.

Eyespot disease caused by the soil-borne facultative fungi Oculimacula yallundae and O. acuformis is the major component of the stem-base disease complex of wheat in temperate regions of the world with a cool and wet climate. In this review, we focus on results of genetic studies concerning both partners of the host-pathogen interaction. This comprises analyses of genetic diversity of the pathogen and identification of particular genes within it, evaluation and screening methods for host resistance, resistance sources and genetics of these resistances, breeding of resistant cultivars in wheat, and application of genetic markers in tagging and tracking of eyespot resistance genes. We also attempt to foresee some of the key issues and developments that may occur in future. The identification of markers tightly linked to eyespot resistance genes is the important research focus opening the door to marker-assisted selection of resistant varieties.
