The Bosana is the most common cultivar of olives in Sardinia. It makes up over 50% of the olive production on the island. [1] [2] The etymology of the name is uncertain, but it could refer to an alleged origin in the territory of Bosa. It is maintained, however, that the cultivar is of Spanish origin. It is used primarily for oil, but can also be eaten. The Bosana is a variety well adapted to less hospitable environments. [3]
The Bosana is particularly common in the olive-growing areas in the centre and north of Sardinia (Sassari, Nurra, Marghine, Planargia) and to a lesser degree also in central southern Sardinia, particularly in some districts of the province of Medio Campidano. This olive variety can also be found in Montenegro. [4]
It is generally accepted that other varieties of local extent are identical to the Bosana. Synonyms that are mentioned in the literature include: Palma, Aligaresa, Algherese, Tonda di Sassari, Sassarese, Olia de Ozzu, Olieddu, Sivigliana piccola and Bosinca. For the most part these are names identifying other varieties of limited range, that are local types of the Bosana.
It is a cultivar of middle strength, with an expansive growth form, plain, elliptic-lanceolate leaves, an open crown, and average size. The olives are of middle weight (2.5–3 g), slightly egg shaped and quite symmetrical, with the greater diameter towards the top. The apex of the stone is rounded and smooth. The surface is covered in tiny lenticels. [5]
The maturation process starts at the apex and advances from there. When mature, the colour of the fruit is black. It is a middle-to-late cultivar, in Medio Campidano it matures between November and December.
Traditionally considered a dual use cultivar, it is in reality mainly used for extraction of oil, and gives a good yield (17–18%). [3] The quality of the oil is improved if the olives are collected early, at the start of the maturation. Its taste is described as "fruity, bitter and spicy". [1]
The fruits of greater size are often transformed to table olives, whether green or black. They are considered to have the quality of not fading during the process.
It is considered a very productive cultivar, well adapted to use in intensive growth olive groves, also under difficult conditions for growing and harvesting. It lends itself better to alternating use, but in intensive olive groves this can be amended with different forms of land management (manuring, irrigation and pruning).
It is generally agreed that the cultivar is self-sterile, [6] so it can take advantage of a certain presence of pollinators. Among the olive cultivars used for pollination are the Nera di Gonnos (Tonda di Cagliari), Pizz'e carroga, Nera di Oliena (Nera di Villacidro or Paschixedda) and Cariasina.
It does not show and particular vulnerability to the major pests, with the exception of the peacock butterfly (Aglais io), this particularly in the dampest parts of north-central Sardinia. It has an average sensitivity to the olive fruit fly, and a high resistance to heat, moths and Pseudomonas savastanoi . [7]
The olive, botanical name Olea europaea, meaning 'European olive' in Latin, is a species of small tree or shrub in the family Oleaceae, found traditionally in the Mediterranean Basin. When in shrub form, it is known as Olea europaea 'Montra', dwarf olive, or little olive. The species is cultivated in all the countries of the Mediterranean, as well as in Australia, New Zealand, North and South America and South Africa. Olea europaea is the type species for the genus Olea.
Arbequina is a cultivar of olives. The fruit is highly aromatic, small, symmetrical and dark brown, with a rounded apex and a broad peduncular cavity. In Europe, it is mostly grown in Catalonia, Spain, but it is also grown in Aragon and Andalusia, as well as California, Argentina, Chile, Australia and Azerbaijan. It has recently become one of the dominant olive cultivars in the world, largely under highly intensive, "super high-density" plantation.
Empeltre is a type of medium-sized, black olive originating in Spain. It is used both as a table olive and to produce a high-quality olive oil.
The Lucques is a cultivar of olives grown primarily in Languedoc in France. It is primarily used as a green table olive. It can also produce high quality oil, but this is hard to extract. Though vulnerable to certain pests, it is relatively resistant to cold and drought.
The Aglandau is one of the more important of approximately a hundred cultivars of olives in France. It is grown primarily in Provence, but also as far away as Azerbaijan and Ukraine. The 'Aglandau' is primarily used for production of oil, but can also be eaten. When used as table olives, the fruit is normally called Beruguette. The oil is highly valued for its fruity taste.
The Salonenque, carrying the name of Salon-de-Provence, is a cultivar of olives grown primarily in Provence. Though it is used for producing oil, and gives a good yield, it is valued primarily as a table olive. It is produced as a so-called cracked olive, which means that the fruit is cracked to speed up the curing process.
The Picholine is a French cultivar of olives. It is the most widely available cultivar in France. Though originally from Gard in southern France, it is today grown all over the world. The Picholine is best known as a cocktail olive, though it is also used to make olive oil. It is the most common variety of olive used for oil from Morocco.
The Olivière is a cultivar of olives grown primarily in the Pyrénées-Orientales region of southern France, where it is the most prevalent variety of olives. It is highly valued for its exceptionally high tolerance to cold. The Olivière is primarily used for oil, and even though the fruit yields a low percentage, the trees carry large quantities of olives, and the oil is of high quality.
The Tanche, probably the best known French olive cultivar, is grown primarily in the Drôme and Vaucluse regions of southern France. It is often referred to as a perle noire, the "Black Pearl of Provence". The Tanche is said to have been introduced to France by the Greeks of Massilia, around the fourth century BC.
The Bouteillan is a cultivar of olives grown primarily in Provence. Originally from the town of Aups in the Var département, it is today grown also in Australia and the United States. It is mostly used for the production of oil. The Bouteillan is vulnerable to certain pests, but has a good resistance to cold.
The Cailletier, also known in English by the Italian name Taggiasca, is a cultivar of olives grown primarily in the Alpes-Maritimes region near Nice and the Riviera di Ponente, Italy. It is best known under the name Niçoise, which signifies its curing method. It is commonly used as an important ingredient in the salade niçoise. It can also be used for the production of oil. This cultivar is particularly susceptible to the olive fruit fly.
The Grossane is a cultivar of olives grown primarily in the Vallée des Baux and Bouches-du-Rhône regions of southern France. Though it can be used to produce oil, it is primarily used as a black table olive. Vulnerable to certain biological pests, it is highly resistant to cold and drought.
The Germaine, also Ghjermana, Ghermana, Germana, and sometimes as Romana, is a cultivar of olives grown primarily in Corsica, but also in parts of northern Italy. Genetically it is close to the cultivar Frantoio, that is grown in the Italian region of Tuscany. The Germaine has a good yield of oil, and the plant is resistant to cold weather.
The Sabine is a cultivar of olives grown primarily in Corsica. In the Balagne region of Haute-Corse it is the main variety. The olive yields an exceptionally high amount of oil; more than 30%. Vulnerable to certain biological pests, it is relatively tolerant of cold. The Sabine olive variety should not be confused with the olive oil produced in the Sabina region of Italy.
The Cayon is a cultivar of olives grown primarily in the Var region of southern France. It is used primarily for the production of olive oil. The Cayon is highly valued for its role as a pollinator of other olive varieties.
The Nera di Arbus, more fully Pecora Nera di Arbus, is a breed of small domestic sheep indigenous to the Mediterranean island of Sardinia, Italy. It takes its name from the comune of Arbus, in the province of Medio Campidano, in the south-western part of the island. It is raised in the provinces of Cagliari, Nuoro, Oristano and Sassari. The breed achieved official recognition in 2008.
Verdale-de-l'Hérault is an olive cultivar developed in the department of Hérault, in the southern French region of Occitanie. The fruit produces a sweet oil with a light and fruity aroma of greenery, nuts, and apple, and exhibits no bitterness.
Ascolano is a cold-hardy table variety olive cultivar from the Marche and Tuscany regions of Italy that is also grown in California for olive oil.
Manzanilla olives ("man-zah-nee-ya") or Manzanillo, also Manzanilla de Sevilla, originally from the area of Seville, Spain, are sometimes referred to as Spanish olives but along with Arbosana, Arbequina, Cacereña, Hojiblanca, Empeltre, and Gordal there are over two hundred varieties grown in Spain as well as other areas.
