Origin & Breeding History: 'Chilean Splash' originated from a cross between '301 UA 1500' and 'Rosara' conducted in 2001 at the Andres Contreras and Boris Contrera breeding program, in Puerta Varas, Chili. 'Chilean Splash' was selected in 2007 for its positive agronomic characteristics and resistance to disease.

Tests & Trials: The comparative trial for 'Chilean Splash' was conducted by Global Agri Services Inc. during the growing season of 2016 in Drummond, New Brunswick. The trial consisted of a single, 19.5 metre long row containing 65 plants spaced 0.3 metres apart for each variety. The distance between rows within the trial was 0.9 metres. Observations and measurements were taken from 10 plants, or 10 parts of plants, of each variety. Mean differences were significant at the 5% probability level based on a paired Student's t-test.
