Contenido:

The global area forested with Eucalypt has exceeded 20 million hectares, distributed in more than 90 countries with the most diverse climates. About 50% of these
surfaces are located in low temperature countries with frequent frost. This is risky for the production and can cause death in juvenile trees; and also combined with
other damages like fungal or insects reducing its growth. The correct species and provenance selection for cold resistance phenotypes is a key factor before starting
the tree improvement program. The comparison of native original climates with the exotic regions can be inferred with climate mapping software, associated
with genetics studies and field tests. A wide range of genetic variability of Eucalyptus genus ensures the availability of species and germplasm resistance. The
species E. globulus, E. dunnii, E. nitens, E. viminalis, E. benthamii and E. pauciflora, are originated from the coldest region of Australia. These species have good
frost resistance and optimal growth. In the case of E. Pauciflora is distinguished by its extreme cold resistance, representing optimal model specie for the physiological
basis to cold resistance researches. These species were used in different countries and continents, producing different results on each of the experiences. The aim of
this article is to review different strategies and results obtained from cold resistant breeding around the world
