The Jackson Low Seeded (LS) grapefruit was discovered by Mr Ferdi Esselen on a farm in the Karino area near Nelspruit in the Mpumalanga Province in South Africa.

The Jackson LS is protected by Plant Breeder’s Rights as per the Plant Breeder’s Right Act No 15 of 1976 (as amended), which prohibits illegal propagation (PBR No PT 3736).

Jackson LS will be planted and marketed within the Premium Grapefruit Cooperative within limited hectarage. Processed product will be marketed as a segmented product under the Sweet Sunrise™ name only.

The origin of the cultivar is a branch mutation on a Jackson Grapefruit tree in the Karino area near Nelspruit.

The Jackson LS has been chosen exclusively for its very high internal quality, unique taste, low naringine levels and excellent external colour.

Komati Group is fortunate to have the sole right to the marketing and production of this Sweet Sunrise grapefruit.
