strawberry Variety
UC Eclipse
NEW - a day-neutral variety excelling in its use for summer plant culture, has also performed very well in autumn-planting regions growing day-neutral varieties.
Adaptable, Fusarium-resistant, and ideal for summer-plant systems
UC Eclipse combines strong Fusarium resistance with high productivity and excellent fruit size. Across Santa Maria and Watsonville trials (2020–2022), average yield about 35–45 % above San Andreas. Fruit are larger and slightly firmer, maintaining good pack out and shape throughout the season. Adapted to summer-plant and low-chill environments, Eclipse is a strong option for warm Argentine regions.
UC Eclipse Key Features
Low chill requirement
350–450 hours
Vigorous plant habit
balanced canopy
Low runner numbers
during fruit production
Flexible seasonality
summer-plant to fall-plant with a long harvest duration
Leading the way is UC Eclipse named as an extreme day-neutral, lending itself to summer planting and therefore season extension opportunities in many parts of the world. Interest in this variety is very high in California and internationally, we are already having huge interest. The exceptional yields of over 4 kgs per plant in some trials have certainly set a new benchmark for the industry.
