Why transition from moneocious to Dioecious and different forms of Dioecious were found in some plant families? Is this an evolutionary adaptation or due to some other reasons?

The course of evolution is steered by selection pressure. For example, giraffes with the longest necks can reach more food, so the "long neck" trait is favored in reproduction. Over large time...

Dear all, I would like to hear ideas on how to speed up multiple trait introgression in plants. For example, introgression of multiple resistance traits or any other interesting trait. Anyone...
