ABSTRACT.
Members of the Fusarium graminearum species complex (FGSC) are the primary pathogens causing Fusarium head blight (FHB), Fusarium graminearum is the main pathogen of FHB and can produce various mycotoxins in wheat, in particular type B trichothecenes. This review presents information on the Fusarium species and chemotypes diversity associated to FHB in wheat in Uruguay. In surveys performed in 2001 and 2002, Fusarium graminearum was the most frequently isolated species (76 %), while other non FGSC species were also identified. Among species from FGSC Fusarium graminearum sensu stricto was the most frequently isolated (97 %), while F. cortaderiae and F. austroamericanum were also identified. The predominant chemotype was 15ADON (95 %), followed by 3ADON (3 %) and NIV (2 %). Isolates identified as F. graminearum sensu stricto were characterized according to the levels of DON production, the aggressiveness on different wheat cultivars, the ability to form perithecia on wheat straw. The sensitiveness to the fungicide tebuconazole of FGSC isolates was evaluated. Most isolates showed high sensitivity levels, but a few resisted higher levels of fungicide. Lower sensitivity seemed to be tied to species since F. cortaderiae isolates showed the highest MIC values. |

In Uruguay, reforestations with Eucalyptus sp. is of fundamental importance to supply paper, pulp, and wood production. This study investigates genetic, productivity, stability, and adaptability parameters in the selection of Eucalypts grandis x Eucalyptus globulus full-sib hybrid clones. The study was conducted in a clonal test, repeated in two different soils types, in Rio Negro State, Uruguay. The population was characterized phenotypically for diameter at breast height (dbh) and genotyped
for SNP markers (EuCHIP60K chip). Mean dbh was similar between sites and the genotype?environment interaction was simple. We found high genotype correlation in clone performance between environments (0.708), indicating the possibility of selecting the same clones for both study locations. Mean heritability between clones (0.724), coefficient of individual genetic variation (10.9 %), and relative variation (0.916), suggest the possibility of gains (estimated at 3.1 % for both sites together) by selecting clones with higher growth rates. A total of 15,196 SNPs were used to confirm parentage and test a genomic selection model for dbh. The predictive capacity was negative (-0.15) given the small population size (78 individuals). The most adaptable material among the tested study sites presented higher values for SNP heterozygosity. Thus, using molecular markers to identify clones responsive to environmental changes can act as a powerful tool in Eucalyptus breeding programs. The hybrid population showed greater adaptability than E. globulus for this region.
