Fruit Appearance
Bazillac forms dense, well-closed, and highly uniform heads with an excellent commercial appearance. Uniformity within the harvest is high – heads are consistent in size and shape, simplifying grading and sales. It holds its quality longer in the field compared to most standard varieties, and post-harvest shelf life is extended – an important advantage for transport and distribution to distant markets.

What is the recommended plant density, spacing, and seeding rate?
For headed lettuce, standard plant density is 9,000–10,000 plants/dka. Recommended spacing is 30–40 cm between rows and 25–30 cm within the row. The seeding rate is 30–50 g transplant/dka at 800–1,000 seeds/g. Bazillac F1 is available in pelleted form, which simplifies precise direct sowing.
What temperature is needed for lettuce seed germination?
The minimum germination temperature for lettuce is 3.5°C and the optimal is 12°C. Above 25°C germination is suppressed, so for spring and autumn sowing it is recommended to monitor soil temperature and, if needed, sow during the cooler part of the day.
Which seasons and growing systems is Bazillac suited to?
Bazillac is designed for spring and autumn production in both greenhouse and open-field systems. The combination of long field holding ability and extended post-harvest shelf life makes it particularly suited to larger producers where harvest flexibility and transport logistics are key to profitability.
What are the main risks when growing this variety?
The main risks in spring-autumn headed lettuce production are downy mildew, fusarium wilt, and viral diseases. Bazillac carries a broad HR resistance package against downy mildew Bl 16-37 and nematodes, plus IR against LMV and Fol, making it reliable under intensive production. Maintaining good ventilation and avoiding overhead irrigation further reduces the risk of fungal disease.
Why choose Bazillac – what problem does it solve?
Bazillac solves three practical challenges at once – flawless commercial appearance, harvest flexibility, and long post-harvest life. In large-scale production for retail chains or export, every additional day of shelf life and every uniform head directly affect profitability. Bazillac F1 is built precisely for these demands.
