African Mahogany (Khayaivorensis) is a species that has aroused the interest of producers in use in commercial plantations for the supply of high quality and high-value wood. This study aimed to verify the existence of differences in diameter and height between African Mahogany progenies in the juvenile phase. They collected seeds from seven main selected trees located in the northern region of the state of Mato Grosso, taking into account the size, being named: AF01, AF40, FS04, FS05, FS11, FS15 and FS30. The test was conducted in a completely randomized design in subdivided plots scheme with seven treatments, four replications, plots of 25 trees, 3,6x4m spacing. Three months after planting the seedlings to the field, they were carried out assessments of the growth in height and stem diameter. It has been found that there are differences among the progeny both the diameter and the height of the plants. The AF01 of progenies stood out as superior both in height and diameter, and the progenies of lower AF40, differing from the others both in height and diameter.
