Key message: Data from multiple traits obtained in this platform, complemented by molecular selection technologies, would increase the prediction value of phenotype/genotype data for new germplasm emerging from the partners breeding pipelines.
Breeding for durable disease resistance in wheat is a challenging task since it is usually quantitatively inherited, thus relying on the accumulation of QTL involved in resistance. This goal could be achieved by the use of a broad spectrum of resistance sources. Moreover, breeders usually need to test their materials in different abiotic and biotic stress conditions to know their adaptability to diverse environments. In order to improve the quality and speed of wheat breeding, CGIAR-WHEAT Initiative has promoted the establishment of field-based Precision Wheat Phenotyping Platforms (PWPP) accessible to public and private breeding partners. In 2015, a partnership between CGIAR and INIA launched the PWPP-Uruguay to test genotypes for multiple diseases: Fusarium head blight (FHB), Septoria tritici blotch (STB) and leaf rust (LR). These diseases are phenotyped each year in separate field trials. Trials are artificially inoculated with pathogen races identified as representatives of the pathogen regional population. Wheat material is sowed in plots; with susceptible checks every 50 entries. Disease severity and other variables characterizing the disease development are measured in internationally standard scales at dates when the expression of plant resistance is optimal. Disease variables are measured at more than one date, to determine the response of the material to the disease at different moments of the epidemic development. Plant height, heading date, growth stage at disease scoring dates and agronomic score are also measured. In 2016, 1544 genotypes were screened for the three diseases. These materials had diversified origins (ten different institutions, public and private, from six countries) and were of different types: from recent commercialized cultivars to ancient ones, advanced lines, International CIMMYT nurseries, mapping populations or association mapping panels. Disease variables were measured at three dates for all materials, except for FHB trial, with two measurements dates. Genotypes could be selected because of their high level of resistance for each set of material (from each institution) in the FHB, STB and LR trial. A 9% to 25% range of genotypes were found highly resistant when selected only from one disease. From these resistant genotypes, up to 5% were resistant against two diseases and near 2% were resistant to the three diseases screened. Data from multiple traits obtained in this platform, complemented by molecular selection technologies, would increase the precision and prediction value of phenotype/genotype data for new germplasm emerging from the partners breeding pipelines.

Background: Cyathostomosis is the infection by nematode larvae of small strongyles belonging to the subfamily Cyathostominae
(cyathostome). It is primarily a disease of young horses with global distribution. The parasites cause severe injuries
to the intestine and the clinically affected animals have severe diarrhea, colic, intussusception, and less frequently intestinal
infarction. The aim of this study is to describe the pathological findings of enteritis by cyathostome on a donkey in Brazil.
Case: A donkey (Equus asinus), crossbred female mongrel, approximately four-months-old, was referred to the Veterinary
Hospital of the Federal University of Campina Grande, Patos, PB, Brazil with a history of trauma. On clinical examination,
complete fracture of the left femur was identified. After performing euthanasia the donkey was necropsied. The animal was
skinny with pale mucous membranes. The perineal region, base of the tail and hind limbs were dirty with yellowish fecal
content. At necropsy, the large intestine had a pasty content and the mucosa was thickened with the multifocal whitish or
dark red nodules. The cut surface of these nodules showed caseous material, sometimes associated with larvae in the submucosa.
Microscopically, it was observed granulomatous and eosinophilic chronic multifocal associated with intralesional
larvae of cyathostome-like nematodes. In the mucosa and submucosa of the colon and cecum, there were multifocal to
coalescing granulomas composed by moderate inflammatory infiltrate composed of eosinophils, macrophages, epithelioid
cells, neutrophils and occasional multinucleated giant cells, surrounded by fibrous tissue and infiltrated by lymphocytes
and plasma cells. At the center of these granulomas transverse and longitudinal sections of nematode larvae with approximately
160-550?m in diameter were observed within the necrotic material. The parasites presented a smooth, thick and
eosinophilic outer cuticle, clear platymyarian muscles, internal cuticular crests, vacuolated lateral strings, and intestine
composed of multinucleated cells in the large colon and caecum. There were no mature gonads, featuring the larval stage.
Discussion: Parasitic infections are the most common diseases that threaten donkey health and performance. In this species,
small strongyles infections are severe, since the larvae can infiltrate and form cysts in the wall of the large intestine
causing serious damage. The most common clinical signs caused by cyathostome are weight loss and diarrhea, which are
non-specific and consequently can lead to an underestimation of the disease occurrence. In this case, massive infection of
small strongyles was observed in the large colon and caecum. In contrast to the large strongyles, the small strongyles do
not migrate through tissue but severely injure the large intestine of donkeys, zebras and horses. Other possible causes of
enteritis in horses include Salmonella spp., Rhodococcus equi, Clostridium perfringens, Clostridium difficile, Neorickettsia
(Ehrlichia) ristcii infections, and idiopathic and neoplastic conditions (lymphoma). In the present report, the diagnosis
of larval ciatostomose was based on clinical signs, and especially in the severity of pathological findings associated with
morphological characteristics of the larvae of nematodes compatible with cyathostome in the large intestine. MenosBackground: Cyathostomosis is the infection by nematode larvae of small strongyles belonging to the subfamily Cyathostominae
