Origin & Breeding History: 'Indigo Cherry Drops' (experimental designations 'P170' and 'S251') originated from a cross conducted at Oregon State University in Corvallis, Oregon, USA. The cross was made in 2005 between the female parent variety 'P20-6', which resulted from a four-way controlled cross using accessions containing wild species germplasm, and the male parent variety 'Sweet Baby Girl'. The resulting progeny was designated as 'P170' and advanced by pedigree selection from the F2 generation to the F5 generation. Selection was based on intense purple colour and excellent flavour. In 2012, approximately ten F6 single plants were massed and designated 'S251' and then advanced to the F8 generation as of 2014.

Tests & Trials: The comparative trials for 'Indigo Cherry Drops' were conducted during the 2015 and 2016 growing seasons in New Maryland, New Brunswick. In each year of test, the seeds were started indoors, transplanted into 10 cm pots, grown on in the greenhouse and planted outdoors in early June. Each plot consisted of 20 plants each of the candidate and reference variety grown in a single row. Plants were spaced 0.60 metres apart within the row and spaced 0.75 metres between rows.
