The spur bearing trait of the Hickman Walnut makes it especially desirable for black walnut orchards. Agronomists at the University of Missouri have created a new cultivar of black walnut that grows ...

Scientists map where the endangered butternut tree can survive, offering new hope for restoring the species across eastern U.S. forests.

UC Davis scientists discovered how walnut trees switch between male and female flowering, a trait that’s been stable for 40 million years. The trees’ “sex timing” depends on two ancient gene variants ...

Three new species of walnuts have been found above the Arctic Circle, remnants of a time when the North and South Poles were covered in forests. In a new study, scientists describe three new, but long ...

By mapping conditions linked to natural resistance which the tree has developed to a pest, researchers are guiding restoration strategies.

UC Davis graduate student Jeffrey Groh has discovered how walnut trees are able to produce flowers of different sexes at different times in the same season. The genetic mechanism is similar to sex ...
