INTRODUCTION
Fs-17 originated as an Italian olive clonal rootstock, a variety known more simply as Favolosa; it has been gaining popularity in recent years given its proven resistance to Xylella bacteria. In particular, it is widespread in areas of central Italy.
Given its characteristics, the Favolosa variety is suitable for both high-intensity olive growing and cultivation for traditional plants.
Compared to the Leccino variety, Favolosa has greater resistance to the bacterium that caused the end of huge expanses of olive trees that characterized the Apulian territory.
Aesthetically, it is distinguished from Leccino for a tendentially pendulous bearing and thin, long, flexible fruit-bearing branches laden with olives that often grow in clusters .

WHY ADOPT A FABULOUS OLIVE TREE?
A strength of this plant is its rapid growth and fruiting; it can boast of this advantage from the second year of planting, because new branches are formed with a predisposition to generalized productivity; to further achieve an increase in production, up to an optimal level, one must wait until at least the fourth year of planting.
From the pressing of the olives we obtain an extra virgin olive oil with a fruity taste, quite intense, with small notes of spicy that prevails over the bitterness.

CULTURAL TECHNIQUES
Exposure
This olive variety is adapted to many climates, regardless of soil and climate conditions, but it is not resistant to cold and water stress. It is characterized by good resistance to abiotic factors and pests, as well as being resistant to Xylella bacteria.
Watering
The fabolosa is an olive tree that does not need large quantities of water , on the contrary, it ripens quietly in dry soil. Irrigation is carried out to obtain better productions .
Watering must be regular , so as to allow the soil to absorb water before the next watering takes place.
Pruning
Fundamental for the life of the olive tree is the pruning phase, from which it is possible to obtain different advantages depending on whether it is an ornamental olive tree or a production olive tree.
The first needs a pruning because dry or diseased branches must be eliminated .
For production olive trees, only branches that have borne fruit need to be removed so that young ones can branch out.
Fruit thinning, for the table variety, allows for larger fruit size without altering production.
To renew older plants and, thus, grow new branches in place of exhausted ones, reconstruction or rejuvenation pruning is necessary.
Fruit
The fruit produced by this variety is of medium size, of a vinous red color. It is possible to obtain an excellent quality oil : it is characterized by a medium-high content of polyphenols and a high content of volatile substances that give it a fruity taste.
Harvest
On average, the productivity obtainable from this variety is high , and the fruit production is constant.
About 18% oil yield can be obtained from this variety, a slightly lower percentage than that obtained from Leccino.
Harvesting can be done by hand : it is necessary to shake the branches and foliage with the poles, in such a way as to drop the fruits on the nets previously spread under the olive trees.
Once harvested, the fruits must be stored in a well ventilated place and in not very thick layers.
