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.

The Atlantic Rainforest is a Neotropical plant formation, traditionally present in Brazil, Paraguay, and Argentina. In Brazil, it followed the country coastal
zone, from Rio Grande do Norte to Rio Grande do Sul, reaching inland the Province of Misiones in North-Eastern Argentina, and east of Paraguay. It is a
threatened tropical forest and its surface has been fragmented discontinuously due to intensive deforestation of the biome, mainly in the twentieth century.
It still holds one of the greatest biodiversities on the planet. It covered important stretches of mountain ranges and escarpments of the Brazilian plateau and was the extension of the Amazon rainforest. It was the second largest tropical forest in expansion in South America. The largest area continues as original surviving forest, the best preserved of this ecosystem is in the Argentine province of Misiones. However, Uruguay has small remnants of Atlantic forest that make it the final limit of the southern distribution. The edaphoclimatic conditions of Uruguay are different from those in the rest of this biome. It has four distinct seasons with contrasting temperatures. The low relief soil does not represent a physical barrier for the winds, making the changes of weather very variable. The aim of this work is to describe five genetic resources species of this biome, its potential for reforestation and productivity in the current scenario of climate change. These are Parapiptadenia rigida, Ilex paraguariensis, Myrcianthes pungens, Eugenia invlolucrata, and Cordia americana. We propose Conservation in situ, improvement and international germplasm interchange.
