Origin & Breeding History: 'BioGold' originated from a cross between 'Novita' and HZ 87 P 200, made at Espel, The Netherlands in 1992. 'BioGold' was selected in 1993 at Espel, The Netherlands and tested under the experimental designation VR 93-913 . A phenotypic recurrent selection technique was utilized in its development.
Tests & Trials: Trials for 'BioGold' were conducted in Drummond, New Brunswick in 2006. All entries were planted in single-row plots. Plots consisted of rows 22 metres long with 30 cm in row spacing and between row spacing of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
