Variación genética en procedencias/progenies de polinización abierta de Eucalyptus dunnii Maiden

growth, adaptability and genetic variability of offspring of Eucalyptus dunnii. The tests were set up in a statistical delineation of compact-block families where the main plots corresponded to the provenances and the secondary plots corresponded to the offspring inside the provenances. Six trees row plot were used with ten repetitions. Height, diameter to breast height, cylindrical volume and plant survival were evaluated at Ipatinga and Guanhaes at 42 and 40 months, respectively. The results showed that the growth in diameter height and volume was high in both towns, while highly significant differences were detected at the provenance level for plant survival at Guanhaes. Mortality was high at Ipatinga. For diameter, height and cylindrical volume of plants, highly significant differences were detected at the family level. Heritability values at Guanhaes were high.
