Origin & Breeding History: 'Dulcita' arose from the cross 'Gloria' by 'N257.1' made in 1994 at Cassin Ranch, Watsonville, Santa Cruz County, California, USA. Fruit and seed were collected to produce seedlings for field planting in 1994 in Watsonville, California. Selection criteria included fruit firmness, sweetness of fruit flavour and easy separation of fruit from the receptacle.
Tests & Trials: The trials for 'Dulcita' were conducted in Oxford Station, Ontario during the 2011 growing season. There were 20 plants of each variety, planted in the spring of 2009. Plants were spaced approximately 60 cm apart in the row and spaced approximately 0.65 metres apart between rows. Measured characteristics were based on a minimum of 10 measurements.
