STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

None:

BACKGROUND AND SUMMARY OF THE VARIETY

The new variety of apple tree ‘PremA17’ was created in the course of a planned breeding program carried out in Hawkes Bay, New Zealand. ‘PremA17’ originated as a result of a controlled cross of ‘A045R13T007’ (not patented, seed parent) and ‘A020R02T167’ (not patented, pollen parent). ‘PremA17’ was selected as a single plant from among a population of seedlings derived from the parents, and was selected for its attractive fruit and its excellent flavor and texture. It is distinguished from its parents by its early harvest season which in Hawkes Bay, New Zealand is the first week of February. A045R13T007 is harvested in late February or early March and A020R02T167 in the third week of February at the same time as ‘Royal Gala’(U.S. Plant Pat. No. 4,121). Asexual propagation by budding was first carried out in Havelock North, New Zealand. The variety has since been observed over a number of asexually propagated generations, and has been found to remain true to type.

DETAILED BOTANICAL DESCRIPTION

The following detailed botanical description is based on observations of three year old ‘PremA17’ apple trees grown at Havelock North, New Zealand. Color descriptions refer to The Royal Horticultural Society Colour Chart, published in 2001. It should be understood that the 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.
