BRIEF DESCRIPTION OF THE VARIETY

‘Dalitoga’ is a whole tree mutation of ‘Imperial Gala’ (not patented). The original mutation was discovered in 1998 in a cultivated block of ‘Imperial Gala’ trees near Lezigne, France, and was asexually propagated for testing purposes by budding at Doue La Fontaine, France in 1999 under breeder\'s reference number R25 A35-GA 35.3. Asexually propagated progeny of ‘Dalitoga’ have been found to retain the unique characteristics of the original ‘Dalitoga’ tree, and remain true to type through successive generations of asexual propagation.

‘Dalitoga’ is similar to its parent in terms of tree shape, vigor, and productivity. However, ‘Dalitoga’ is distinguishable from its parent in several respects, as summarized in Table 1:

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY

The following is a detailed botanical description of ‘Dalitoga,’ a new and distinct cultivar of Malus pumila Mill., based on observations made on the original tree from 1998 to 2001, and during the 2002, 2003, and 2004 growing seasons of specimens of the second generation planted at Angers, France in 2001 and 2002. All colors are described according to The Royal Horticultural Society Colour Chart. It should be understood that the botanical and analytical characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with location and season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant, or any group of plants, of the new variety may vary from the stated average.
