Varietal profile and pomological characteristics

Production specifications and crop cycle

The Seraphine strawberry plant is distinguished as a non-remontant variety , which means that it concentrates its production over a single, intense period during the season. Its earliness is classified as mid-early , positioning itself advantageously on the harvest calendar just after the Clery variety, known for its early maturity.

Quality criteria and organoleptic properties

The fruits of the Séraphine are large in size , a major asset for marketing and profitability, and their shape is regular, naturally classifying them in "class 1" for the professional market . Visually, they display a bright and shiny red color , uniform across the entire berry, guaranteeing an attractive and homogeneous presentation. Although the precise figures are not always disclosed, the average size of a Séraphine fruit is estimated between 15 and 18 grams , and can even exceed 18 to 22 grams in optimal conditions, which positions it favorably among the standards of "large fruits" on the French professional market. The flesh, for its part, offers a remarkable balance between sugar and acidity , characterized by a frank and pleasant aroma. The sugar level (Brix) is generally estimated between 7 and 9°Brix , ensuring a constant and sought-after flavor. Its texture is firm, giving it a pleasant crunch when eaten, without softness or excess juiciness. This firmness is an essential criterion for downstream logistics, estimated at around 0.5 to 0.8 kg/cm² using a penetrometer at harvest .

Cultivation techniques in production

Preparation of the substrate and rational fertilization

To fully exploit the potential of the Seraphine Strawberry, soil preparation is essential. This variety prefers light to medium- heavy soil , the essential characteristic of which is excellent drainage, in order to prevent root asphyxiation and fungal diseases. A substantial supply of organic matter is strongly recommended, with a recommendation of 3 to 5 kg of mature compost or well-rotted manure per square meter before planting, thus enriching the substrate and promoting optimal root development. The ideal soil pH for Seraphine is between 5.5 and 6.5 , i.e. slightly acidic to neutral. Soil salinity, or electrical conductivity (EC), must be controlled and maintained below 1.5 mS/cm , with a maximum tolerance of around 2.0 mS/cm without significant impact on yield or quality. It is advisable to loosen the soil to a depth of 30 to 40 centimeters to facilitate rooting.

The Séraphine strawberry plant is also suitable for high-density soilless cultivation , whether in gutters or in bags of substrate, a method increasingly adopted by professionals to optimize yields and health control. An indicative fertilization plan for this variety, based on the needs of non-remontant seasonal strawberries, recommends a total application of 90 to 120 kg/ha of Nitrogen (N) , split between planting and the growth phases; 80 to 100 kg/ha of Phosphorus (P₂O₅) as basal fertilization; and 170 to 200 kg/ha of Potash (K₂O) , mainly for soil preparation. Monitoring of trace elements such as Magnesium (30-40 kg/ha) , Iron, Manganese, Zinc, Boron and Calcium is essential, with adjustments based on soil analyses.

Climatic requirements and stress tolerance

The hardiness of the Seraphine Strawberry is an asset, the plant tolerating active frosts on flowers down to -2°C to -3°C with adequate protection (sprinkling, veil), while the collar and the stump can withstand winter temperatures down to -13°C to -15°C . The optimal temperature range for its vegetation is between 8°C and 28°C , with vigilance required above 30°C where the growth and quality of the fruits can be affected.

Production performance

Yield potential and harvest schedule

The Seraphine strawberry plant is a very productive variety . Under optimal professional growing conditions, it is realistic to expect an average yield of 1 to 1.2 kg of strawberries per plant per season . This translates, for typical planting densities of 45,000 to 60,000 plants per hectare, into an impressive harvest potential of 35 to 60 tonnes per hectare .

The Séraphine Strawberry harvest window is mid-early and is concentrated from the beginning to the end of June, a strategic period for the strawberry market in France. The majority of production, approximately 70% of the total harvest, is obtained over an intensive period of two to three weeks , generally between the 23rd and 26th week of the year (corresponding roughly to the beginning and end of June). This concentration allows for efficient planning of labor and rapid marketing of large volumes.

Commercial sorting and quality standards

In terms of fruit quality at packaging, Séraphine is distinguished by a very high proportion of first category fruit (Class I) , generally between 80 and 90% of total production . The waste rate remains low, around 10 to 15% , a key indicator of profitability. Uniformity of size is also remarkable at peak production, with more than 85 to 90% of the fruit having a homogeneous size and shape , thus facilitating sorting and packaging operations.

Crop protection

Resistance to bioaggressors and pathologies

The robustness of the Séraphine strawberry plant is a major asset for producers. This variety has very good resistance to major strawberry fungal diseases , including powdery mildew (Podosphaera aphanis) and gray mold (Botrytis) , which significantly reduces dependence on phytosanitary treatments. However, regarding common pests such as thrips, aphids, spider mites, the weevil (Anthonomus rubi) or Drosophila suzukii, current sources do not document specific resistance for Séraphine. The management of these pests must therefore rely on standard integrated pest management practices, including regular monitoring and the use of biological control. Similarly, Séraphine does not show greater resistance to Xanthomonas fragariae (angular spots) than reference varieties on the market, requiring special vigilance and adequate preventive measures. On the other hand, its firmness contributes to good to very good resistance to picking injuries , an essential point for maintaining the quality of the fruit after harvest.

Production economy and varietal supply

Séraphine is primarily intended for fresh consumption , a market segment where its added value is maximum. Its large size, impeccable presentation and flavor make it a preferred choice for direct sales, local markets and specialized distribution in short circuits. The varieties selected for industrial processing (jam, freezing, agro-industry) meet different criteria (cooking resistance, freezing suitability, mass yield) which are not the priority areas for development of Séraphine. The firmness of the fruit and its good post-harvest behavior are logistical assets for fresh marketing, allowing satisfactory transport and presentation. Professional Séraphine plants are generally available at a unit price ranging from €0.18 to €0.35 , depending on the packaging and quality, offering good value for money given its yield potential and the quality of its fruits.

The Séraphine strawberry plant is renowned for its reliability and robustness , adapting well to both outdoor and indoor operations, making it a versatile choice for professional growers. Its ease of picking , thanks to its large, regular fruits, optimizes harvest times and reduces labor intensity, thus contributing to greater production profitability. Compared to other mid-early varieties, Séraphine rivals benchmarks such as Senga Sengana or Surprise des Halles , offering increased resistance to powdery mildew and superior general hardiness , while maintaining a balanced size and flavor profile.
