Powdery mildew caused by the airborne ascomycete fungus Blumeria graminis f. sp. hordei (Bgh) is one of most common diseases of barley (Hordeum vulgare). This, as with many other plant pathogens, can be efficiently controlled by inexpensive and environmentally-friendly genetic resistance. General requirements for resistance to the pathogens are effectiveness and durability. Resistance of barley to Bgh has been studied intensively, and this review describes recent research and summarizes the specific resistance genes found in barley varieties since the last conspectus. Bgh is extraordinarily adaptable, and some commonly recommended strategies for using genetic resistance, including pyramiding of specific genes, may not be effective because they can only contribute to a limited extent to obtain sufficient resistance durability of widely-grown cultivars. In spring barley, breeding the nonspecific mlo gene is a valuable source of durable resistance. Pyramiding of nonspecific quantitative resistance genes or using introgressions derived from bulbous barley (Hordeum bulbosum) are promising ways for breeding future winter barley cultivars. The utilization of a wide spectrum of nonhost resistances can also be adopted once practical methods have been developed.

“…Barley (Hordeum vulgare L.) has played a pivotal role in Old World agriculture since its domestication about 10 000 years ago (Piffanelli et al, 2004) and is the fourth most important cereal crop in the world, after wheat, maize and rice (Czembor, 2001;Anonymous, 2009b). Barley is also one of the most important cereals in Latvia.…”

“…It is particularly prevalent under cool conditions when the maximum daily temperature does not exceed 25°C (Dreiseitl et al, 2006). Powdery mildew is one of the most destructive foliar diseases of barley in regions such as Europe (Czembor, 2001). In Latvia, where the climate is moderate, the pathogen develops in two stages: in the vegetation period, numerous conidia are formed, which ensure propagation and dispersal of the fungi; in autumn, cleistothecia with spores are formed on senescing parts of plants.…”

“…More than 100 mildew resistance genes have been identified in barley cultivars, landraces, and wild or related Hordeum species. Mlg was the first gene introduced on a large scale in the 20 th century (Brown and J¸rgensen, 1991;Czembor, 2001). Many mildew resistance alleles have been identified on chromosome 4H and chromosome 1H of the barley genome.…”

“…Most genes in the Mla locus have lost their effectiveness during the recent few years in different regions of Europe, due to the high level of pathogenic variability of powdery mildew (Müller et al, 1996;Caffier et al, 1999;Limpert et al, 1999;Hovm¸ller et al, 2000;Dreiseitl, 2004a;2004b;Kokina and Rashal, 2005a;2012). Most of the powdery mildew resistance genes, including Mla1, Mla3,Mla6,Mla7,Mla9,Mla12,Mla13,Mlat,Mlk,Mlg,Mlh and Mlra,are commercially derived from the Mediterranean region (Czembor, 2001). Barley plants carrying recessive alleles of the Mlo locus are resis-PROCEEDINGS OF THE LATVIAN ACADEMY OF SCIENCES.…”

samples of the causal agent of barley powdery mildew were collected in Daugavpils (south-eastern Latvia, Latgale region), Stende (north-western Latvia, Kurzeme region) and Priekuïi (north-eastern Latvia, Vidzeme region). Virulence frequency, complexity and pathotypes were calculated in the pathogen populations. Significant differences of virulence detected by the genes Va1, Va3 and Va13 occurred among samples of the pathogen population collected in different parts of Latvia. Nei index, Müller's index, Kosman index, Shannon index and Simpson index showed considerably higher diversity in Daugavpils and Stende during 2009-2010. In Daugavpils, the population of Blumeria graminis f.sp. hordei was particularly characterised by high diversity.

This study was conducted to determine the resistance to powdery mildew in 218 barley landraces collected in Near East (Israel, Lebanon, Syria, Turkey, Iran, Iraq), North Africa (Egypt, Algeria, Morocco) and Southern Europe (Greece, Bulgaria, Yugoslavia, Italy, Spain). Plants with resistant reactions were found in 31 (14%) landraces from which 41 single plant lines were selected. These lines were tested with 20 differential isolates of powdery mildew. Eight (19.5%) lines originated from 7 landraces (5 from Israel, 1 from Syria and 1 from Greece) were resistant to all powdery mildew virulence genes prevalent in Europe. The value of new identified sources of highly effective powdery mildew resistance to breeding programes and barley production was discussed.
