Origin & Breeding History: 'V92301' arose as a single selection from the cross of 'Harrow Diamond' and 'V790638' conducted in 1992 at the Horticultural Research Institute of Ontario, Vineland Station, Ontario. Selection criteria included maturity date, yield, fruit characteristics, improved disease resistance, productivity and very low incidence of split pits.

Tests & Trials: Trials for 'V92301' were conducted at the University of Guelph, Department of Plant Agriculture, Vineland Campus during the 2010 to 2012 growing seasons. Trees were planted in 2006 on 'Bailey' rootstocks. Spacing between trees was 4 metres in the row and 5.5 metres between rows. Measured characteristics were based on 25 measurements.
