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 is mainly for areas with high Black rot pressure. Due to Optima’s resistance against Black rot, this variety performs very well in areas where it is a problem. It’s a strong plant that takes 80-95 days to mature form transplants. 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
