Origin & Breeding History: 'S10-B7' (experimental designation XC1070, S183443 and 04DL183443) was developed from the cross 87463 / 57133 made in Arva, Ontario in 2001. Generations F1-F2 were grown in a winter nursery in Kekaha, Hawaii. The F3 was grown in Arva, Ontario in 2002. Generations F4-F5 were grown in Hawaii. The F6 generation was grown in Arva, Ontario in the summer of 2003 where single plants were selected that fall. The progeny of these plants were grown in a single replicate trial in 2004. One of these lines was identified as 04DL183443 and was selected based on superior agronomic attributes and retained for further testing. 04DL183443 was subsequently tested in multiple environments in Ontario and Chili until 2005-2006. 'S10-B7' carries the Rps 1c gene for protection from phytophthora root rot (Phytophthora megasperma f.sp. glycinea).
Tests & Trials: Tests and trials were conducted in Arva, Ontario during the years 2008-2009. Plots consisted of 2 rows with a row length of 4 metres and row spacing of 75 cm. There were two replicates.
