Introducing the 'Triple Crown' mulberry variety
The thornless mulberry variety 'Triple Crown' is today one of the most promising references for professional producers in France. Originally from the United States, it is distinguished by the exceptional size of its fruits, its remarkable vigor, its tolerance to diseases , and a flavor very appreciated both fresh and in processing . It meets the requirements of short supply chains, self-service picking and sustainable agriculture.
Fruit characteristics
The fruit of 'Triple Crown' is of exceptional size , frequently reaching 3 to 5 cm in length for an average weight of 8 g , well above market standards (Loch Ness, Chester, wild blackberry). It has an elongated shape , with a shiny black skin when ripe and a colorimetric evolution typical of blackberries (green > red > black). The flesh, probably dark purple , is very juicy, fleshy and melting , with little grainy sensation.
In terms of taste, the fruit develops a soft, sweet and fragrant flavor , accompanied by a slight balancing acidity . It is sweeter and more aromatic than industrial varieties such as 'Chester' or 'Loch Ness'. The Brix level reaches 12.7% , which indicates an excellent sugar content .
Post-harvest storage is good , with storage for 3 to 5 days in a cold room (1-2°C). Beyond this, the loss of firmness becomes noticeable, which directs marketing towards quick sale or freezing .
Fruiting period
'Triple Crown' is a non-remontant variety , with a single annual harvest, generally from August to October , with peak production occurring between August and September . Flowering ranges from May to August , depending on the region.
Commercial uses
Thanks to its large size, intense aroma, good firmness and absence of thorns , 'Triple Crown' is ideal for fresh consumption , especially for direct sale or self-picking. It is also perfectly suited to artisanal and industrial processing : jams, jellies, syrups, pastries, compotes, juices and frozen products.
Its juice content, estimated at 80-85% of fresh weight, makes it a choice variety for juices and coulis. In organic farming, its hardiness and natural resistance to disease are major assets.
Plant characteristics
'Triple Crown' develops a semi-erect to climbing habit , with long, flexible, thornless stems, facilitating all cultural interventions. The plant reaches 2.5 to 3 meters in height and up to 2 meters in spread depending on training. Some sources indicate heights of up to 5 meters in optimal conditions.
The vigor is very strong , superior to that of varieties such as 'Loch Ness' or 'Chester'. This vigor requires rigorous annual pruning , particularly in winter (January-February), to remove the stems that have fruited and encourage the growth of young branches.
The root system is superficial to intermediate , concentrated between 30 and 60 cm deep , which requires fresh, rich and well-drained soil . The use of mulch is recommended to limit evaporation.
Cultural needs and management
'Triple Crown' requires a lot of training , as the stems are not very rigid. A multi-wire trellis system is recommended to optimize growth, facilitate picking and ensure good aeration of the foliage.
The variety is self-fertile , requiring no pollinator. However, planting a single cultivar in blocks encourages cross-pollination between plants , which can improve yield.
Resistance and adaptation
The variety is distinguished by excellent resistance to fungal diseases of the Rubus genus (anthracnose, botrytis, powdery mildew, rust), limiting the use of fungicides by up to 100% compared to sensitive varieties . Nurserymen's ratings rank it 4 to 5 out of 5 for health resistance.
It is also generally resistant to the main insect pests , not requiring systematic treatment, which makes it an interesting candidate for technical routes in sustainable or organic agriculture .
In terms of hardiness, 'Triple Crown' commonly tolerates temperatures down to -15°C to -20°C . There are reports of resistance down to -30°C , but this requires confirmation. It is advisable to protect young plants from cold winds and provide winter mulching if necessary.
It also has good drought tolerance (2 to 3 weeks without watering in deep soil), but prolonged water stress will impact size and yield. Regular irrigation is still recommended in summer.
Finally, the variety tolerates calcareous soils up to 12-15% active limestone , as long as they are well drained. On the other hand, heavy and asphyxiating soils should be avoided.
Propagation and rootstocks
Propagation on its own roots (cuttings, layering) is the reference method, guaranteeing the absence of thorns and good vigor. Grafting is rare but possible on Rubus fruticosus (blackberry) or Rubus caesius , to improve tolerance to humidity in certain specific soils.
Performance and profitability
Under optimal conditions, the yield reaches 5 kg per adult plant per year , with a first significant harvest from the 2nd year and a peak of production from the 3rd year . The average yield is around 5 kg per plant.
Melliferousness
'Triple Crown' is a honey-producing variety , its flowers producing abundant nectar between May and August, which effectively attracts bees and other pollinators .
Longevity
The productive lifespan of the stumps is estimated at between 10 and 15 years , subject to good sanitary and cultural maintenance. The stems are biennial, which implies constant renewal by pruning.
