About this variety

Winterbor F1 is an internationally established curly kale hybrid from Bejo, a major Dutch vegetable seed breeder whose seed lines are distributed in India through the general vegetable seed trade. It is known internationally as a tall, vigorous plant with strong, frost-resistant stalks that hold their shape and bunch well after cutting, qualities suited to a late-season or overwintering crop in a cool hill climate. As a modern F1 hybrid, it offers more predictable vigour and uniformity across a planting than an open-pollinated type, at the usual hybrid trade-off of needing fresh seed each season.

Sowing & cultivation

  • Sowing timeAugust–September in hill and cool-plains conditions, well suited to a late-season or overwintering crop given its frost resistance
  • Seed rateFollow the seed packet's recommended rate — hybrid seed is dearer per kg than open-pollinated seed, so nurseries are typically raised more sparingly
  • Spacing45 × 30 cm, or slightly wider given the variety's tall, vigorous habit

Advantages & considerations

Why farmers may choose it

  • Frost-resistant and specifically suited to a late-season or overwintering crop in cool hill climates.
  • Strong stalks that hold shape and bunch well after cutting, an advantage for market presentation and handling.
  • Backed by an internationally established seed breeder's quality control, addressing the mislabelling risk of unbranded kale seed.

Things to consider

  • Hybrid seed cannot be saved true-to-type for the next season — fresh seed must be bought each time.
  • As an imported hybrid, availability and price depend on the general vegetable seed trade rather than a dedicated local Indian distributor network.

Suitable regions

Bejo's vegetable seed line is distributed in India through the general seed trade — suited to hill and cool-plains cultivation generally, not tied to an officially recommended state.

  • Himachal Pradesh
  • Uttarakhand
