Marilan (Marianna 2624 + Adara) rootstock 

The Marilan rootstock is commonly used for cherry tree plantations in soils where root asphyxiation does not allow the use of other patterns. The Marilan pattern results from the combination of the Mariana and Adara patterns, if you continue reading, you will discover the reason for this successful combination and its main features.

Plum Rootstock for Cherries Adara

The Plum Adara is a cherry pattern selected by the experimental station of Aula Dei in Zaragoza (Spain). Registered in 1995, this rootstock comes from a selection of the Japanese Plum (Prunus cerasifera ). The variety of Adara plum has been an important step in the cherry tree cultivation. Being the Adara rootstock, the first known variety of plum compatible with varieties of Sweet Cherry. Thanks to Adara, the cherry graft on plum is possible and peach, almond tree feet can be used… for cherry growing.

The Adara rootstock allows us to take advantage of the best adaptation of the plum to heavy soils where the root asphyxiation of the cherry tree is inevitable.

Currently sales of the Adara plum pattern have declined in favor of the Marilan combination (Marianna + Adara).

Adara rootstock features:

Vigor of the Adara pattern: The Adara rootstock is vigorous.

Propagation: The Adara pattern can be vegetatively multiplied by taking a semi-woody limb root.

Graft: Adara is usually grafted by gusset at the end of August or during the winter break in March.

Productivity: The Adara rootstock supports a high load level, allowing very good productivity. It improves the precocity slightly with respect to the pattern of frank cherry. In addition, it advances maturation between 3 and 5 days.

Adara pattern pruning: It is necessary to perform the usual cherry pruning to maintain good gauges.

Adara plum root: Resistant to suffocation root and does not generate sierpes. It adapts well to heavy soils.

Compatibility: It is compatible with a significant amount of commercial varieties of cherry sweet. In fact it is the first variety of plum known to be compatible with cherry.

Warning: some varieties of cherry are not compatible  (list of compatible and incompatible cherry varieties).

Recommendations: Interesting for its good resistance to suffocation, rot and adaptation to heavy soils.

Marianna 2624 stone fruit rootstock

The Marianna 26-24 rootstock is obtained by the University of Davis (California) in the United States. Its genetic origin is a cross between Prunus Cerasifera (Garden Plum) and Prunus Munsoniana (Ornamental Shrub). It spread during the forties (1940-1950). Compatible with stone fruit (apricot, plum…), Marianna 2624 rootstock could not be used in patterns for cherry plantations until recently. The discovery of the Adara plum, compatible with cherry, has allowed its use in plantations of various varieties of cherry. The combination between Marianna and Adara is known as (Marilan).

Marianna rootstock features:

Marianna rootstock vigor: The Marianna 26-24 rootstock allows you to get cherry with a high vigor.

Propagation: The pattern Marianna 2624 can be multiplied using micropropagation techniques.

Graft: The Marianna rootstock is directly compatible with plum varieties and some apricot trees.

Productivity: The Mariana 26-24 rootstock allows to obtain good productions even in poor soils or after replanting.

On the other hand, it allows to advance the collection between 3 and 5 days.

Vigor: It is a vigorous pattern, with a slightly greater vigor than Saint Lucie 64 , it adapts well to frames of 6×4 meters and densities of 400 plants / ha. According to some studies, it improves both vigor and productive capacity in Saint Lucie 64. American sources recommend a 6×6 meter frame.

Marilan rootstock (Mariana Adara)
Comparison of vigor between rootstocks

Cherry pattern: It is not directly compatible with the cherry tree. Therefore, the use of Adara is required as a bridge between Mariana and certain sweet cherry varieties.

Marianna plum root: This rootstock is very tolerant of root asphyxiation and tolerates well the conditions of drought. It is also moderately resistant to iron chlorosis, typical of limestone soils where iron is blocked.

Resistances: Other advantages of the Marianna plum 26-24 are its important resistance. It is immune to the nematodes of the gills, resistant to Phythoptora and Rosellinia Necatrix, of moderate resistance to Armillaria. On the other hand, it is sensitive to agrobacterium (bacteria that generates tuberculosis) and the injuring nematodes.

Recommendations: Marianna 2624 is a good pattern for areas of replanting or areas where there are problems of root asphyxiation and fungi. Due to its vigor, it is appropriate to plant it together with varieties of high productivity.

Marilan Plum (Marianna-Adara)

The Marilan rootstock is the union of the plum varieties Marianna and Adara. As we have seen Marilan is a plum pattern with excellent characteristics. The Marianna rootstock is very tolerant of root asphyxiation and allows planting in soils where it was previously unfeasible. Therefore, and its important resistance, the root of the Mariana plum 26-24 is used instead of directly using the Adara plum.

Adara for its part, is compatible with a significant amount of commercial varieties of sweet cherry. Therefore, it has a fundamental role as a bridge in the union between the Mariana 26-24 rootstock and the corresponding cherry variety.

Important: For a perfect affinity between Adara and the cherry variety, it is important to leave 40cm of Adara bridge between Marianna and the cherry graft.

The Marilan pattern, therefore, has the excellent features and resistance offered by the Marianna plum 2624 and, in addition, thanks to Adara it is compatible with different varieties of sweet cherry.

Curiosities: Currently the Marilan rootstock is well known for its high vigor and high productive capacity.
