Unimproved landraces and wild relatives of crops are sources of genetic diversity that were lost post domestication in modern breeding programs. To tap into this rich resource, genome wide association studies in large plant genomes have enabled the rapid genetic characterization of desired traits from natural landrace and wild populations. Wild barley (Hordeum spontaneum), the progenitor of domesticated barley (H. vulgare), is dispersed across Asia and North Africa, and has co-evolved with the ascomycetous fungal pathogens Pyrenophora teres f. teres and P. teres f. maculata, the casual agents of the diseases net form of net blotch and spot form of net blotch, respectively. Thus, these wild and local adapted barley landraces from the region of origin of both the host and pathogen represent a diverse gene pool to identify new sources of resistance, due to millions of years of co-evolution. The barley - P. teres pathosystem is governed by complex genetic interactions with dominant, recessive, and incomplete resistances and susceptibilities, with many isolate-specific interactions. Here we provide the first genome wide association study of wild and landrace barley from the Fertile Crescent for resistance to both forms of P. teres. A total of 14 loci, four against P. teres f. maculata and ten against Pyrenophora teres f. teres, were identified in both wild and landrace populations, showing that both are genetic reservoirs for novel sources of resistance. We also highlight the importance of using multiple algorithms to both identify and validate additional loci.

“…All three of the major barley loci conferring resistance to P. teres f. maculata confer seedling resistance (Liu et al , ) and are designated Rpt4, Rpt6 and Rpt8, respectively (Table ). The Rpt4 locus located on chromosome 7H was found in Galleon, CI9214, Keel, Tilga, Chebec (Williams et al , , ), PI67381, PI84314 (Tamang et al , ) and possibly TR251 (Grewal et al , ). The Rpt6 locus was found on the short arm of chromosome 5H in CI9819 (Burlakoti et al , ; Manninen et al , ) and Rpt8 was found on chromosome 4H in Q21861 (Franckowiak and Platz, ; Friesen et al , ).…”

Summary Pyrenophora teres f. teres and P. teres f. maculata are significant pathogens that cause net blotch of barley. An increased number of loci involved in P. teres resistance or susceptibility responses of barley as well as interacting P. teres virulence effector loci have recently been identified through biparental and association mapping studies of both the pathogen and host. Characterization of the resistance/susceptibility loci in the host and the interacting effector loci in the pathogen will provide a path for targeted gene validation for better‐informed release of resistant barley cultivars. This review assembles concise consensus maps for all loci published for both the host and pathogen, providing a useful resource for the community to be used in pathogen characterization and barley breeding for resistance to both forms of P. teres.

A recombinant inbred line mapping population was developed from a cross between the heritage malting barley (Hordeum vulgare ssp. vulgare) cultivar ‘Golden Promise’ and ‘Otis’, a feed barley cultivar developed in the 1960s suitable for the high dry plains. The Golden Promise/Otis recombinant inbred line (RIL) population (MP‐3, NSL 545640 MAP) consists of 190 F5:7 individuals. The parental lines exhibited significant differences in several agronomic traits including height, heading date, yield/plant, and lodging. Transgressive segregation in the RILs was evidenced by the broad range of values observed for these agronomic traits. The RIL population was genotyped using the Illumina 50k iSelect single nucleotide polymorphism (SNP) arrays. Of the 10,810 polymorphic markers that were identified between the two parents, 4617 markers were used for generating a genetic map that spanned 4566 cM with an average distance of 1 cM between markers. The fact that Golden Promise is a malting cultivar developed in the United Kingdom, versus Otis, a feed barley bred in the United States for dryland cultivation, indicates that this population may be useful in identifying the genetic basis of many other traits.
