Graft hybrid

The stock receives the scion and serves as the root system for the grafted plant.

[9][7][4] Graft hybridisation is explained by horizontal gene transfer, DNA transformation, and the long-distance transport of mRNA and small RNAs.

[12] Hybridisation through grafting has the potential to create economically significant hybrid plants.

[7] Graft hybridisation is a simple and practical method for breeding woody plants, particularly helpful for overcoming reproductive isolation and difficulties due to highly heterozygous genotypes.

This idea has been widely rejected for more than a century, until it has been proven to occur with modern methods.
