Presentation of the Kosmos-cov apricot tree for professional producers in France

The Kosmos-cov apricot tree is an early variety developed by PSB (Pépinières et Sélections Bernard) and protected by a Plant Variety Certificate (PVC) . This variety is distinguished by its high productivity, good-sized fruit and excellent tree stability, making it particularly interesting for producers wishing to optimize their production at the start of the season.

Geographical origin and varietal status

The Kosmos-cov apricot tree is the result of a varietal selection program, although its precise geographical origin is not mentioned. It is protected by a COV , which means that its propagation and marketing are regulated . Any commercial exploitation requires a license from the PSB breeder, guaranteeing consistent quality of the variety.

Tree characteristics

The Kosmos-cov is a medium to strong tree, with a habit not specified in the available sources. Like many modern apricot trees, it is suitable for intensive orchard management with regular pruning to optimize production and aeration of the foliage.

Its flowering is early and requires compatible pollinators , as it is not self-fertile . It is essential to select varieties with simultaneous flowering to ensure efficient pollination and maximize productivity.

Fruit characteristics

Kosmos-cov fruits are medium to large (AA) in size , with an average weight of 67.6 g per fruit . Their shape is round , with a light orange skin and a red blush on the sun-exposed part, which gives them strong commercial appeal.

The flesh is firm , ensuring excellent shelf life after harvest and good resistance to transport. This characteristic is valuable for producers targeting long supply chains and large-scale distribution.

In terms of taste, Kosmos-cov apricots are rated AA in organoleptic quality , which suggests a fruit balanced in sugar and acidity, suitable for fresh consumption.

The fruit has very good stability on the tree , limiting losses linked to premature falls and facilitating a more staggered harvest.

Earliness and harvest period

Kosmos-cov is a very early variety , maturing around May 22. This precocity allows producers to capture the market for early apricots, which is often more profitable, and to optimize their harvest schedule.

Its productivity is high , with an observed average of 61.6 kg per tree , which makes it a particularly profitable variety for professionals.

Pollination

The Kosmos-cov apricot tree is not self-fertile and requires cross-pollination to ensure good fruit set. Sources do not specify recommended pollinator varieties , but it is advisable to associate Kosmos-cov with early-flowering apricot trees to maximize fruit set.

Consultation with specialist nurserymen is recommended to select the best varietal combinations based on local conditions.

Resistance to diseases and parasites

Available sources do not provide precise information on the disease and pest resistance of Kosmos-cov . It is therefore recommended to adopt rigorous monitoring and appropriate cultural practices to limit the risks associated with the main apricot diseases:

• Moniliosis , which affects flowers and fruits in humid conditions.
• Bacteriosis , responsible for cankers on branches.
• Sharka (Plum Pox Virus) , whose sensitivity to Kosmos-cov is not documented.

A preventive technical itinerary must be put in place, in particular by choosing suitable rootstocks and ensuring good aeration of the trees.

Resistance to environmental stresses

No specific information on Kosmos-cov's resistance to drought, limescale, and root asphyxiation is mentioned in the available sources. However, like most apricot trees:

• It tolerates drought moderately once well established, but benefits from regular watering during the fruiting period.
• It tolerates slightly calcareous soils , although selecting a suitable rootstock can improve this tolerance.
• It requires well-drained soil , as apricot trees are susceptible to root asphyxiation .

The choice of rootstock will influence resistance to abiotic stresses and must be adapted to the specific conditions of the orchard.

Compatible and recommended rootstocks

Although the sources do not specify the specific rootstocks for Kosmos-cov , several options commonly used for apricot trees in France can be considered:

• Montclar® : Provides vigor and good adaptation to well-drained soils.
• Rubira® : Interesting for filtering soils and better vigor management.
• Rootpac® R : Promotes tolerance to harsh conditions and improves productivity.
• Rootpac® 20 : Suitable for heavier soils.

Before choosing a rootstock, growers are recommended to consult experts to optimize the growth and production of Kosmos-cov according to local constraints.
