Variety Description

Varieties used for comparison: 'Satina' and 'Sante'

Summary: The plants of 'Milva' are shorter than the plants of 'Satina' and taller than the plants of 'Sante'. The tubers of Milva' have a yellow and smooth skin whereas it is light beige and rough for 'Satina'. 'Milva' has tubers that are oval in shape, whereas they are round in the reference varieties. The light sprout of 'Milva' is smaller than that of the reference varieties. The base and the tip of the light sprout of 'Milva' have more anthocyanin colouration than 'Santina' and 'Sante'. The base of the light sprout of 'Milva' has a high proportion of blue in the anthocyanin, whereas it is absent to low in the reference varieties. The pubescence at the base of the sprout is absent to very sparse in 'Milva' and dense in 'Satina'.

SKIN: yellow, yellow at base of eye, weak to medium anthocyanin when exposed to light, smooth texture

LIGHT SPROUT: small, ovoid, moderate number of root tips, short lateral roots
BASE: very strong anthocyanin, high proportion of blue, absent or very sparse pubescence
TIP: smaller than base, intermediate habit, strong anthocyanin, medium pubescence.

Origin & Breeding History: 'Milva' was selected from the F1 progeny of a cross between 'Dunja' and 'Nena' made in 1986 in Kaltenberg, Germany. The variety was selected based on negative agronomic criteria.

Tests & Trials: Trials for 'Milva' 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.
