Sapora is an attempt to improve on Rubinette, which has an outstanding reputation for flavour but is not the easiest apple to grow. It is a cross between Rubinette and Fuji, and ripens very late in the season (similar to Braeburn).
Fuji is well regarded for its unequalled keeping qualities, yet surprisingly Sapora could not really be considered a keeper, and will will only keep for a few months in a cold store. Reports suggest that this is an apple that is at its best soon after picking.
One of the main challenges for growers of Rubinette is its tendency to produce small fruit. Fruit size with Fuji is normally good, and Sapora also seems to have a better size than Rubinette. This increased size may be because unlike Rubinette and Fuji, Sapora is a triploid variety, with an extra set of chromosomes. Triploid varieties are often more vigorous than the more usual diploid varieties, and this can help with productivity, fruit size, and disease resistance.
