Dipteryx alata Vog. presents an excellent economic potential because of its multiple uses. However, it is currently threatened as a result of the degradation of the biome in which it occurs, the Brazilian Cerrado. Therefore, our goal was to provide subsidies for future breeding and ex situ conservation programs of D. alata. We evaluated genetic variation in growth, stem form, and wood quality traits in a progeny and provenance test planted in a random complete block design. The traits were measured in 37-year-old trees. Significant effect for provenance was obtained for all evaluated traits except bifurcation, but progeny effect was significant only for acoustic wave velocity (AWV). The estimates of individual narrow sense heritability were of low magnitude for all traits except AWV (0.24 ± 0.09). Eleven groups were formed based on Mahalanobis genetic distance with 83.1% of progenies allocated to one group. Dipteryx alata has genetic variability between progenies and provenances that can be explored to obtain genetic gain, especially for AWV. We also recommend the use of multi-trait selection index to obtain gains for both growth and wood quality traits. Controlled pollination between individuals from different progeny groups would increase variability in next generation breeding.

Dipteryx alata Vog 的生长和木材质量特征。（豆科）后代和来源测试

双翅鸟 alata Vog。由于其多种用途，呈现出极好的经济潜力。然而，由于它所在的生物群落巴西塞拉多的退化，它目前受到威胁。因此，我们的目标是为 D. alata 未来的育种和异地保护计划提供补贴。我们在以随机完整块设计种植的后代和种源测试中评估了生长、茎型和木材质量性状的遗传变异。这些性状是在 37 岁的树上测量的。除分叉外，所有评估性状均获得了显着的出处效应，但后代效应仅对声波速度（AWV）显着。除 AWV (0.24 ± 0.09) 外，所有性状的个体狭义遗传力估计值均较低。根据 Mahalanobis 遗传距离形成 11 个组，其中 83.1% 的后代分配到一个组。Dipteryx alata 在后代和种源之间具有遗传变异性，可以通过探索获得遗传增益，特别是对于 AWV。我们还建议使用多性状选择指数来获得生长和木材品质性状的增益。来自不同后代群体的个体之间的受控授粉将增加下一代育种的可变性。
