Origin & Breeding History: 'S18-R6' (experimental designation 04DL186048) was derived from the cross 89694 / 62755 made during the summer of 2001 in Arva, Ontario. The F1-F2 generations were grown near Kekaha, Hawaii in the winter of 2001-2002. The F3 was grown in Arva, Ontario in the summer of 2002. The F4 generation was grown in a winter nursery in 2002-2003 and single plants were selected and threshed individually. The progeny were yield tested in a single replicate test in 2003 and one of these lines, identified as 04DL186048, was selected for further testing based on superior agronomic traits. The variety has been tested in multiple environments since 2004 in Ontario and the USA.
Tests & Trials: Tests and trials were conducted over the years 2005, 2006, 2007, 2008 in Arva, Ontario. Plots consisted of 2 rows, with a row length of 5 meters and a row spacing of 75 cm. There were 2 replicates each year.
