Variety Description
Varieties used for comparison: 'Estima' and 'Provento'
Summary: 'Elisabeth' has a shorter plant height and shorter leaves than 'Provento'. The star in the corolla of 'Elisabeth' is more prominent than in 'Provento'. The light sprout of 'Elisabeth' is smaller than that of the reference varieties. 'Elisabeth' has a spherical light sprout while 'Estima' has an ovoid to broad cylindrical light sprout and 'Provento' has an oval light sprout. The light sprout base of 'Elisabeth' has a moderate level of anthocyanin colouration, whereas that of 'Estima' has no anthocyanin. The light sprout tip of 'Elisabeth' has less anthocyanin and less pubescence than that of 'Provento'.

Origin & Breeding History: 'Elisabeth' was selected from the F1 progeny of the crossing of 'VE82-96' and 'Cilena' made in 1991 in Bant, The Netherlands. The selection process was based on negative agronomic traits.
Tests & Trials: Trials for 'Elisabeth' were conducted in Drummond, New Brunswick in 2005. A block design was used with four replicates per variety. All entries were planted in single-row plots and each entry had one replicate per block. Plots consisted of rows 5.5 metres long and between row spacing of 91 cm. Measured characteristics were based on 10 measurements. Colour determinations were made using the 1986 RHS colour chart.
