Summary of the presentation "Varietal strategy: aligning genetics and profitability" by Jorge Duarte (Hortitool Consulting), presented as part of the Berry Area 2026 event programme.
In the blueberry and berry sector, genetic innovation is no longer a purely agronomic issue, but has become the main driver of profitability, risk management and commercial positioning.
With the European market expanding strongly, with estimated annual growth of 8.4% until 2030, competitive pressure requires companies to make a strategic step forward.

Today, varietal choice determines access to premium retail channels, the ability to respond to climate change and the long-term economic resilience of the plantation.
Carefully balancing licence royalties, club models, harvest windows and quality parameters therefore becomes an essential step in aligning with the increasingly strict specifications of international retail.
Key takeaways
1. The wrong genetics can cost up to four seasons.
Choosing an unsuitable variety can result in up to four lost seasons and sunk costs ranging from 15,000 to 60,000 euros per hectare, compromising access to market windows and retail contracts.
2. A new variety can take up to 16 years to move from the laboratory to the field.
The varietal development process can take up to 16 years. For this reason, it is essential to actively monitor innovations and test new selections for at least two full seasons on pilot plots of 0.5-2 hectares before commercial adoption.
3. Southern Highbush genetics are advancing rapidly.
Southern Highbush varieties have grown by 200% in just a few years. These low- or no-chill selections offer accelerated production cycles and greater flexibility against winter temperature anomalies.
4. Premium positioning requires objective parameters.
Access to premium segments is linked to measurable requirements, such as sugar levels above 12 degrees Brix and shelf life of more than seven days. Poor post-harvest firmness can generate waste and value losses of up to 40%.
5. Risk is managed through a structured varietal portfolio.
Agronomic and commercial risk management requires that no more than 40% of company acreage be allocated to a single cultivar, ensuring smoother coverage of multiple harvest windows.
What emerges from the presentation
The approach to blueberry cultivation is undergoing a radical transformation.
Profitability calculations can no longer be based on static projections of yields and prices, but must incorporate the growing volatility of the supply chain, cost pressure and the rapid evolution of market standards.
The real weakness in fruit and vegetable business plans often lies in a superficial reading of hidden costs and external variables.
Factors such as licence royalties, the costs of managing club programmes, labour and post-harvest losses have a decisive impact on the final profitability of a plantation.
In particular, during harvest operations, labour can account for between 55% and 70% of variable costs, a figure that is still too often underestimated during the planning stage.
Variety is a financial decision
In modern blueberry production, choosing a cultivar does not simply mean deciding what to plant.
It means defining the commercial calendar, risk level, unit cost, access to premium markets and the ability to recover the investment within the expected timeframe.

The hidden cost of the wrong genetics
Varietal choice is one of the most difficult decisions to correct after planting.
Genetics that are not suited to the production context, commercial window or final customer requirements can generate losses for several consecutive seasons.
The damage does not only concern agronomic yield. A non-competitive variety can compromise access to large-scale retail programmes, reduce the possibility of entering premium segments and weaken the farm's bargaining position.
Sunk costs can reach 15,000-60,000 euros per hectare, considering the initial investment, plantation management, lost profitability, varietal replacement and loss of market windows.
In this sense, a varietal error is not just a technical problem, but a capital risk.
From laboratory to field: why innovation must be monitored
The path that brings a new variety from the laboratory to commercial field production can take up to 16 years.
This structural slowness makes it essential for growers to actively monitor genetic innovations, avoiding late reactions to market changes.
At the same time, commercial adoption cannot be improvised.
Before investing on a large scale, a new selection must be tested locally for at least two full seasons, on pilot plots of significant size, typically between 0.5 and 2 hectares.
Only field trials conducted in the farm's real production context make it possible to evaluate yield, quality, climate response, labour requirements, shelf life and the variety's commercial behaviour.
| Strategic variable | Operational risk | Recommended response |
|---|---|---|
| Unsuitable genetics | Loss of production seasons, contracts and commercial windows. | Local trials for at least two seasons before large-scale adoption. |
| Royalties and club programmes | Higher access costs and stricter commercial constraints. | Evaluate the relationship between licence cost, commercial support and achievable price. |
| Chilling requirement | Risk of irregular flowering and unstable production. | Integrate Southern Highbush genetics in areas exposed to temperature anomalies. |
| Insufficient shelf life | Waste, claims and value loss of up to 40%. | Select cultivars with firmness, keeping quality and shelf life of more than seven days. |
| Excessive reliance on a single variety | Concentration of agronomic and commercial risk. | Do not exceed 40% of the farm's acreage with a single cultivar. |
Open varieties and club programmes: two different logics
The genetic landscape shows a rapid polarization between open varieties and protected club programmes.
Open varieties guarantee lower entry costs and greater management flexibility, but they increasingly struggle to meet the standards required by high-end retail.
Club programmes, on the other hand, offer greater commercial support, more structured positioning and access to selective channels, but require minimum volumes, strict protocols and inflexible quality standards.
The evaluation therefore cannot be limited to the cost of the royalty.
It is necessary to understand whether the programme truly allows for a price premium, access to better customers, lower commercial risk and sales continuity.
Consumers buy experience, not the botanical name
A crucial point concerns final market perception.
Consumers, especially in European and North American markets, rarely evaluate the individual botanical variety.
Very often, the cultivar name does not even appear on the packaging.
What consumers recognize is the experience associated with the product or brand: texture, sweetness, crunchiness, size, freshness and repeatability of purchase.
For this reason, replicating the same quality profile throughout the year becomes a more defensible asset than simply chasing volumes.
Genetics therefore serve to build a stable consumption promise, not just production performance.
Southern Highbush: the answer to climate anomalies
Climate instability is forcing a drastic renewal of plantations.
Strong winter temperature fluctuations endanger hormonal balance and flowering in Northern Highbush selections, which are highly dependent on prolonged chill accumulation.
This vulnerability explains the rapid growth of Southern Highbush genetics, which have increased by 200% in just a few years.
These are low- or no-chill selections, in some cases capable of entering optimal production even with thresholds below 150 chill hours.
These varieties make it possible to increase production flexibility, reduce climate risk and open up new growing geographies.
The Mediterranean as a new platform for continuity
The adoption of more flexible genetics allows Mediterranean regions and the Iberian Peninsula to significantly extend the supply calendar.
In some production contexts, the goal becomes covering market windows for ten or even twelve months a year.
This changes the competitive logic of European blueberries.
It is no longer just a matter of producing in the traditional window, but of building a varietal portfolio capable of serving multiple periods of the year, avoiding concentrated peaks and improving continuity in retail relationships.
The varietal portfolio is a risk insurance policy
Distributing acreage across several cultivars reduces exposure to genetic errors, climate anomalies, harvest peaks and price instability.
The operational rule of not exceeding 40% of acreage with a single variety becomes a concrete risk-management tool.
Premium: Brix, shelf life and firmness determine value
Access to premium segments no longer depends on generic quality assessments.
Retail requires objective and measurable parameters.
These include sugar levels above 12 degrees Brix, shelf life of more than seven days, good post-harvest firmness, adequate berry size and lot uniformity.
When these requirements are not met, the loss of value can be significant.
Poor post-harvest firmness, rapid deterioration or inadequate keeping quality along the logistics chain can generate waste, commercial downgrades and losses of up to 40%.
Premium quality is therefore not just a matter of higher price: it is a technical system that must hold up from field to shelf.
The Andalusia case: premium genetics and substrate cultivation
The transition towards more advanced industrial and agronomic logics produces measurable results when properly planned.
Data from advanced districts in Andalusia show that a structured move to premium varieties grown in substrate systems can increase grower prices by more than a quarter.
This improvement supports higher net margins, up to +21%, and enables a return on investment estimated at around 3.4 years.
The message is clear: genetics generate profitability when they are embedded in a coherent system that includes substrate, technical management, harvest calendar, post-harvest quality and commercial positioning.
In summary
Varietal strategy is now one of the main competitiveness tools in blueberries.
Genetic choice affects yield, unit cost, retail access, climate risk, production calendar, shelf life and achievable price.
In a growing but increasingly selective European market, growers must abandon approaches based only on theoretical yield or the reputation of a cultivar.
Local trials, hidden-cost assessment, balanced varietal portfolios and objective quality parameters are required.
The future of blueberries will not be determined only by how many tonnes are produced, but by how much value each hectare can generate through genetics, quality and commercial positioning.
