ABSTRACT.
The objective of this study was to compare a conventional genomic model (GBLUP) and its extension to a linear reaction norm model (GLRNM) specifying genotype by environment interaction (G*E) for tick resistance in Brazilian cattle. Tick counts (TC) from 4,363 Hereford and Braford cattle from 146 contemporary groups (CG) were available of which 3,591 animals had BovineSNP50 Illumina v2 BeadChip genotypes. The reaction norm covariate was based on CG estimates of TC from a first-step model. Analysis was conducted based on adapting the single step GBLUP/REML procedure. Five-fold cross validation based on K-means and random partitioning was used to compare the fit of the two models. Cross validation correlations were strong and not significantly different between models for either partitioning strategy. Nevertheless, it seems apparent that G*E for tick infestation exists and can captured by GLRNM models. |

Abstract.
In Uruguay, 228 hectares are cultivated with garlic, with an average yield of 2 ton/ha. Propagating material lacks any sanitary or productive selection. Garlic is worldwide affected by viruses of the poty and carlavirus groups that considerably decrease yields. Reports from the Las Brujas Experiment Station (EELB) in 1978 already showed the almost total infection by viruses of the garlic crop in Uruguay. Some works were started in 1991 to provide information to support an EELB program to produce virus-free material of garlic: a) Serological identification of the viruses that infect Uruguayan garlic crops. b) Antisera production and adjust of techniques for virus detection. c) Indexing of in vitro propagated materials. Flexous rod-shaped viral particles were observed using serological techniques combined with electron microscopy. These particles showed a strong serological reaction in the immunosorbent electron microscopy with decoration technique (ISEM-D) against onion yellow dwarf virus, leek yellow stripe virus, carnation latent virus antisera and other antiserum called "garlic yellow stripe virus", probably obtained since a mixture of garlic viruses. Viruses mixture from garlic was purified and an antisera was obtained. It was used in ISEM-D and ELISA detecting concentrations of purified viruses less than 1.25 μg/ml, and showing clear differences between healthy and diseased plants. Eighty one in vitro tissue-cultured plants were tested using ISEM, detecting viral particles in 63 of them (78%). Nearly half (47%) of the infected plants were detected using the antisera prepared against the mixture of viruses, requiring the use of others antisera to detect the rest of them.
