Abstract
Nut tree species have a great economic and cultural value for many countries across the world. Their highly nutritious content makes them one of the most favourite healthy foods of the global population, with strong evidence of their positive impact on human health. Nut tree crops are very diverse in terms of nut chemical content and shape, growing climates, and domestication history. However, all of them have a very long juvenile phase that makes classical breeding challenging and time consuming. Also, their cultivation is very resource demanding. The application of genomic-assisted breeding can accelerate the development of adaptive cultivars of nut tree species. In this article, we summarize recent successes in genomics for nut tree crops, specifically almond, chestnut, hazelnut, pecan, pistachio, and walnut. We report the recent discoveries on the genetic control of target traits for the genetic improvement of these species, with suggestions for future directions and breeding applications.
