Delicious has become the most widely planted apple cultivar in the world. The latest survey of Ohio plantings indicate that 33% of young non-bearing trees are Delicious. A recent survey (7) of the literature on Delicious indicates that over 100 different strains or mutations of the parent cultivar exist. All the strains offered for sale have some degree of improved fruit color compared to original Delicious. In addition to fruit color changes, a number of strains have spur type growth habit (a high proportion of laterals are spurs rather than long shoots). Spur growth habit has been shown (5) to reduce tree height 13% and tree spread 38% compared to standard Delicious growth habit on M.7.
