Origin & Breeding History: 'Elgar' originated from a cross between Y66-13-636 and VE71105, made at Beetgumermolen, The Netherlands in 1987. 'Elgar' was tested under the experimental designation FOB 84-60-13 and selected in 1989 at Middenmeer, The Netherlands. A phenotypic recurrent selection technique was utilized in its development.
Tests & Trials: Trials for 'Elgar' 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.
