OUTSTANDING QUALITIES
- Intermediate resistance to black rot
- Excellent summer variety
- Exceptional heat tolerance
- Very high yield potential
Optima is the new summer variety from Sakata that’s in the same class as Tenacity. Optima has resistance to Black rot (Xcc) disease making it perfectly suited to areas with high Black rot pressure – especially in summer. It’s a strong plant that takes 80 - 95 days to mature from transplant. The big frame protects the heads very well against sunburn and wind damage. Heads are semi round to round with a good head weight. Optima’s frame has an upright growth habit, so water doesn’t accumulate in the bottom part of the plant.
SPECIAL VARIETAL REQUIREMENTS
- Excellent results are consistently achieved for harvest through the warm season
- Mature heads can tolerate cool and frost conditions well
- Avoid early and late sowings in cooler areas and growing through winter in cold areas as bolting may occur
- Contact area representative for a sowing guide
