Variety Description

Varieties used for comparison: 'Desiree' and 'Asterix'

Summary: 'Murato' has stronger anthocyanin colouration on the stem and peduncle than 'Desiree' and 'Asterix'. The tuber eyes of 'Murato' are predominantly apical, whereas they are evenly distributed in the reference varieties. 'Murato' has a spherical shaped light sprout while 'Desiree' has a broad to narrow cylindrical light sprout and 'Asterix' has an ovoid light sprout. The light sprout of 'Murato' is smaller than that of the reference varieties.


PLANT: semi-upright growth habit, leaf type foliage structure

STEM: very strong anthocyanin evenly distributed, main stem medium in thickness, swelling of nodes absent or very low

LEAF: dark green, intermediate silhouette, strong anthocyanin in rachis and petiole
TERMINAL LEAFLET: medium ovate, acuminate tip, cordate base, moderate frequency of coalescence of terminal and lateral leaflets
LATERAL LEAFLETS: medium size, narrowly ovate, acute to acuminate tip, cordate base, moderately deep veins, moderate waviness of margins, medium glossiness, sparse pubescence on blade (at apical rosette), moderate presence of secondary leaflets

INFLORESCENCE: large, flowering profusion medium to high, persistent buds, absent to weak anthocyanin in buds
COROLLA: large, red-violet colour, strong anthocyanin on inner surface, prominent star
PEDUNCLE: very strong anthocyanin

TUBER: round to oval, eyes intermediate in depth and predominantly apical, eyebrows slightly prominent, medium yellow to dark yellow flesh with no secondary colour
SKIN: red, red at base of eye, strong anthocyanin when exposed to light, smooth texture

LIGHT SPROUT: small, spherical, few root tips, short lateral roots
BASE: strong anthocyanin, moderate proportion of blue, medium pubescence
TIP: equal in size to base, closed habit, anthocyanin absent to very weak, medium pubescence.

Origin & Breeding History: 'Murato' was selected from the F1 progeny of the crossing of 'AR83-303' and 'KO83-1372' made in 1989 in Bant, The Netherlands. The selection process was based on negative agronomic traits.

Tests & Trials: Trials for 'Murato' 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.
