Evaluation
The variety Rubin achieves good fruits size as well as high yields. The medium firm, large fruits are easy to pick because of their very long stalks and even distribution on the tree. Because of the late flowering period Rubin is recommended as pollinator for 'Regina'. Due to the susceptibility of the wood and flowers to frost damage and the increased tendency to Pseudomonas infection only appropriate sites should be chosen. The fruits can soften rapidly in high temperatures during harvest time.
