Haploid embryogenesis in treesexample, inbreeding in dioecious trees is restricted to sib-mating, never selfing. Although haploids could be used to speed up bredeing programs, to study inheritance of qualitative traits and to establish linkage maps, there are relatively few tree species which have been amenable to induction of haploids.

Advances in the protoplast culture of woody plants). Thus, it will be possible to use protoplast-based genetic engineering to add one or a few desirable traits to already proven varieties so that the development time for a saleable product can be reduced.

Maturation and rejuvenation in woody speciesribe changes such as reduced growth rate and type of branching due to increased size and complexity of the tree, which disappear when a scion is grafted onto a young rootstock or when a stem cutting is rooted.
