It severely limits plant growth and development as well as agricultural characteristics including the final yield. The aim of this review is to summarise recent results of the breeding of barley (Hordeum vulgare) and wheat (Triticum aestivum; T. durum) for improved resistance to drought stress. First, drought-associated terms and definitions are outlined and plant strategies to cope with drought are presented. A brief overview of plant physiological mechanisms involved in water uptake and release is provided. Photosynthesis-related parameters (CO2 availability and associated features such as ribulose-1,5-bisphosphate carboxylase/oxygenase activity, 13C discrimination activity, water use efficiency) are discussed due to the crucial role of plant leaf stomata in both photosynthesis and water management. The second part describes the present state of research on drought resistance-associated traits in barley and wheat. Different strategies of plant water management aimed at maximising the final yield under various types of drought stress are discussed. Possibilities of the detection, identification and characterization of quantitative trait loci (QTLs) in barley and wheat germplasm are discussed and the future approaches to breeding for enhanced drought resistance as a complex physiological and agronomical trait are outlined.

China Title: Genetic analysis and molecular mapping of leaf rust resistance genes in the wheat line 5R618 Abstract: The wheat (Triticum aestivum L.) line 5R618, bred at the China Agricultural University, is resistant in the seedling stage to the majority of the current Chinese pathotypes of wheat leaf rust (Puccinia triticina). To identify and map the leaf rust resistance gene in the 5R618 line, F2 plants and F2:3 families from a cross between 5R618 and Zhengzhou5389 (susceptible) were inoculated in the greenhouse with the Chinese P. triticina pathotype THJP. Results from the F2 and F2:3 populations indicate that a single dominant gene, temporarily designated Lr5R, conferred resistance. Using the molecular marker method, Lr5R was located on the 3DL chromosome. It was closely linked to the markers Xbarc71 and OPJ-09 with genetic distances of 0.9 cM and 1.0 cM, respectively. At present only one designated gene (Lr24) is located on the 3DL chromosome. The genetic distance between Lr5R and Lr24 confirms that Lr5R is a new leaf rust resistance gene.

Genotype data were compared with technological malting quality parameters. The analysis of variance showed significant differences between varieties used for the given PGI and varieties used for other beer types in six variables. Three clusters of varieties specific to the PGI and three clusters specific to malting barley genotypes for other beer types were identified using a Bayesian approach. The remaining four clusters expressed effects of parent lines. The discrimination analysis based on malting quality and molecular variables identified only one barley breeding line suitable for the PGI "České pivo".

Screening for resistance in the seedling and first clonal generations is a cost-effective and efficient way to reduce the time needed to create a new variety. Unlike the phenotypic assessment of resistance to nematodes, marker-assisted selection (MAS) can be applied at early stages of selection. The frequent question among breeders is about the impact of early selection for resistance on the agronomic value of finally selected resistant progeny. The study presents a relationship between the presence of markers TG689 and 57R and some agricultural traits in field grown seedlings and three successive vegetative generations. Both markers are linked to H1 gene, which confers resistance to the golden cyst nematode Globodera rostochiensis. Clones with these markers had higher total tuber and starch yield than those without the markers. A negative relationship between marker presence and quality was not observed.

This is one of the most destructive pathogens of this species. A new cleaved amplified polymorphic sequence (CAPS) marker C2-25 was developed for the detection of the dominant gene Frl, which confers tomato resistance to FORL. C2-25 was amplified from a conserved ortholog set II (COSII) sequence C2_At2g38025. The XapI-derived restriction product of 700 bp was informative for the identification of FORL resistant tomato genotypes and can be used as a diagnostic marker in tomato breeding programmes and hybrid seed production.

Determination of virulence was based on infection types on Thatcher near-isogenic lines (NILs) with the resistance genes Lr1, Lr2a, Lr2b, Lr2c, Lr3a, Lr9, Lr10, Lr11, Lr13, Lr15, Lr17, Lr19, Lr21, Lr23, Lr24, Lr26 and Lr28, respectively. Virulence for Lr9 and Lr 19 occurred only sporadically in the investigated period. On average, virulence for Lr2a, Lr2b, Lr24 and Lr28 was low. The highest frequency of virulence was found for Lr3a, Lr10, Lr11, Lr13, Lr15, Lr17, Lr21, Lr23 and Lr26. During the investigation period we recorded a shift from prevailing virulence for Lr2c and avirulence for Lr1 to avirulence for aLr2c and virulence for Lr1. Ther virulences in the leaf rust population were compared with matching resistance genes in the registered wheat cultivars. The most frequent resistance gene was Lr37, while the genes Lr3a and Lr26 were less frequent.
