Strawberry plants have now joined an elite group of plants that include grapes, rice, and soy. What do these plants have in common? They have all had their genome completely mapped. The strawberry species that has been sequenced is Fragaria vesca, the woodland strawberry (also known as the Alpine Strawberry, one of the “wild” strawberry varieties). The strawberry plant genome is what determines the life cycle of the strawberry plant, how many strawberries it will produce, and everything else about it. It is the life code that is passed from generation to generation of strawberries through either the strawberry runners or the strawberry seeds.
With the Strawberry Plant Genome Sequenced…
With the strawberry plant genome sequenced in a collaborative effort involving 75 researchers from 38 research institutes, new research is expected to yield breakthroughs in multiple areas. Through more detailed study of strawberry genetics, it is hoped that the metabolic pathways of ripening will now be better understood. Also, enzymatic activity in the production of aromatic compounds in strawberries and other related species will be better understood.

Strawberry plants have a very unique diversity when it comes to their genetic makeup. The genetics of most things are relatively complex, but the genetics of strawberry plants throw an additional twist into the mix. Strawberry plant species have varying numbers of chromosomes (see the Strawberry Plant page for introductory information).
Most species are diploid, meaning they have two sets of chromosomes, one set of chromosomes is normally inherited from each parent. Polyploidy, a condition more common in plants, occurs when multiple pairs of chromosomes are present in the genetic component of an organism. Strawberry species and hybrids can be diploid, tetraploid, pentaploid, hexaploid, heptaploid, octoploid, or decaploid (having 2, 4, 5, 6, 7, 8, or 10 sets of the seven strawberry chromosomes, respectively).
Use the sortable table below to see a list of the polyploid genetics of strawberry plants. The various major species of strawberries are listed, along with their genetic makeup and informational notes. For more information, see the Strawberry Varieties page.
