OUTSTANDING QUALITIES
     ATTRACTIVE, TRUE SAVOY
     EXCELLENT FIELD HOLDING
     SUPERIOR COLOUR AND QUALITY

Grace is an attractive, true Savoy hybrid cabbage
and is well suited to warm season production.
Grace matures around 75 - 80 days from
transplanting for large heads and about 40 days
from transplanting for ‘baby’ heads. Heads are very
uniform, firm, semi-round shape, small to medium
in size with a dark green colour. Head quality and
flavour are excellent.     Plant size is small with
compact but strong wrapper leaf cover. Grace is
also successfully grown as a ‘baby’ cabbage. The
baby heads are round in shape and look very attractive when pre-packed in punnets. Field holding
ability is excellent. Grace has intermediate resistance to Fusarium yellows (Foc). Grace is used
mainly in the fresh, pre-pack and processing market.

SPECIAL VARIETAL REQUIREMENTS
  Grace is suited to sowing throughout the year in warm areas and most of the year except during
   April and May in cool areas
  Contact area representative for a sowing guide

Resistance: is the ability of a plant variety to restrict the growth and development of a specified pest or pathogen and/or the damage they cause when compared to susceptible
plant varieties under similar environmental conditions and pest or pathogen pressure. Resistant varieties may exhibit some disease symptoms or damage under heavy pest or
pathogen pressure (HR = High resistance, IR = Intermediate resistance).
