Title: Cherry tree named ‘Tip Top’

Description:
Genus and species:  Prunus avium.    
   Variety denomination: ‘Tip Top’. 
   BACKGROUND AND SUMMARY OF THE VARIETY 
   The new cherry variety ‘Tip Top’ originated as a chance seedling of unknown parentage. The seedling was found in a commercial ‘Sweetheart’ cherry (not patented) orchard planted in 2001 near Wenatchee, Wash. In 2005, it was observed that the seedling was markedly different from the surrounding trees. It was similar in appearance to a ‘Rainier’ cherry tree (not patented), but was distinguished from ‘Rainier’ by its sweeter, more crisp fruit and its early maturity. Additionally, fruit of the newly discovered plant was found to be resistant to bruising and browning. Trees were propagated from the seedling by budding onto ‘Mazzard’ rootstock near Wenatchee, Wash., to determine whether the desired characteristics of the chance seedling would carry through to asexually propagated progeny. It has been found that the distinguishing characteristics of the tree and fruit of the newly discovered variety are reproduced through asexual propagation and have remained stable through successive generations. 
   ‘Tip Top’ is a new and distinct cherry tree notable for its sweet, crisp fruit, reduced tendency to bruise, non-browning flesh, and early maturity as compared to ‘Rainier’.

   DETAILED BOTANICAL DESCRIPTION 
   The following detailed botanical description is based on observations of the original tree of the variety, planted in 2001 and grown on ‘Mazzard’ rootstock (not patented). Observations were recorded and photographs taken during the 2007 and 2008 growing seasons at Wenatchee, Wash. 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. Colors are described with reference to The Royal Horticultural Society Colour Chart (2001).
