5 adapted varieties
In Bretagne, the local agronomic conditions (Cfb — oceanic temperate climate, 1014 growing degree days, silt loam soil at pH 5.5, 305 frost-free days) are particularly favorable to linseed cultivation.
Favorable growing period: May to October.
Recommended varieties: GALAAD, LS Anthocya, LS Kaolin
Sufficient growing degree days (1014 GDD) to complete the linseed cycle.
Notable summer water deficit (-127 mm). Pick drought-tolerant varieties.
Long frost-free season (305 days), allowing broad crop cycles.
Favorable growing period: May to October.
Slightly acidic soil (pH 5.5). Liming can improve performance.
GALAAD is a very productive and early spring oil flax linseed with very high oil content and excellent agronomic behaviour.
LS Anthocya is an anthocyanin-rich winter oil flax variety with 44.4% oil content and a 57.7% C18:3 rate.
Kaolin is a very productive spring oil flax linseed with excellent lodging tolerance and broad destination suitability.
LS RIVIERA is a spring oil flax variety with early to semi early flowering and 44.5% oil content with 59.8% C18-3.
LS Apalache is a winter oil flax variety combining early development with 45% oil content and a strong omega-3 profile.
Key agronomic watchpoints in this zone:
Brittany, an oceanic terroir with 305 frost-free days and 1,014 GDD, offers conditions well suited to spring linseed. Acidic silt-loam soils (pH 5.5) require prior liming but otherwise suit the crop perfectly. Galaad, LS Kaolin and LS Riviera can diversify rotations dominated by maize and winter cereals, providing a low nitrogen-demand previous crop. Cool summer (17.4°C) limits stress.
The varieties recommended above are pre-selected based on local climate, soil and disease pressure. Top picks combine adapted maturity, yield stability and the specific disease tolerances needed in Bretagne.
The favorable sowing window is typically from May to October. Exact timing depends on soil temperature (>10°C at 5 cm), weather forecast and your local agronomist's advice.
Yields depend on variety, agronomic management and the season. Under typical Bretagne conditions with good practices, our adapted varieties target stable, competitive commercial yields. Precise ranges are available on request.
