Obviously, rate of growth is no predictor of fruit quality, but I assume any varieties that can grow well in Tucson's hot sun and poor soil will also ripen well. So, of the 12 varieties of UCD cuttings that survived my fumbling efforts to get them rooted and established in pots, the two that have grown the largest are UCR135-15S (photo; 26.5 inches of new growth) and Tena (18 inches). Wimpiest was Black Madeira (photo) at only 3.5 inches, but it put out a lot of leaves and branches so I'm hoping that next year, in the ground, it will break out of its FMV-induced "dwarfism" and make some real progress.
