Abstract
‘RKD’ is a Gala-type apple tree distinguished by its early maturing and early full-coloring fruit.
Description
Latin name: Malus domestica Borkh.
Variety denomination: ‘RKD’.
‘RKD’ is a new and distinct variety of apple tree Malus domestica Borkh that originated as a spontaneous two-limb mutation of ‘Tenroy’ gala (U.S. Plant Pat. No. 4,121). ‘RKD’ was discovered by the inventor in a commercial apple orchard in Royal City, Wash. in 2006, and was selected for further observation because of its distinctive early maturing and early full-coloring fruit. Buds were taken from the distinctive limbs in 2007 and budded onto rootstock for further observation and evaluation. The variety has since been reproduced by budding at Royal City, Wash., and has been observed to remain true to type through successive asexually propagated generations.
‘RKD’ is a Gala-type apple tree distinguished by its early maturing and early full-coloring fruit. A comparison of ‘RKD’ to ‘Tenroy’ and other Gala-type varieties ‘Simmons Gala’ (U.S. Plant Pat. No. 10,840), ‘Banning Gala’ (U.S. Plant Pat. No. 13,753) and ‘Waliser Gala’ (U.S. Plant Pat. No. 8,673) is shown in Table 1.

The photographs show two- and three-year-old trees, and were taken during the 2013 and 2014 growing seasons at Royal City, Wash.
The following detailed botanical description is based on observations made during the 2013 and 2014 growing seasons at Royal City, Wash. of trees growing on ‘Cepiland’ rootstock (U.S. Plant Pat. No. 7,715), planted in 2011. All colors are described according to The Royal Horticultural Society Colour Chart (Fifth edition, 2007). It should be understood that the characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and will 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.
