U.S. Patent PP17,464
This cultivar is a joint release with Dr. Mark Herrington of Queensland Primary Industries. Primarily grown and sold in Australia, ‘Rubygem’ has an excellent sugar acid balance, which gives it a sweet tasting flavor. ‘Rubygem’ has a moderate level of rain tolerance with skin cracking and etching of the fruit surface around the seeds. In Florida, blotchy ripening can also occur in wet weather if nutritional balance is not correct. This clone was named ‘Rubygem’ for its attractive deep, ruby red color.
