Variety Description

Varieties used for comparison: 'Meeker', 'Willamette' and 'Chemainus'

Summary: The plants of 'NR7' have an upright growth habit whereas the reference varieties are semi-upright. The dormant canes of 'NR7' are significantly shorter than those of the reference varieties. 'NR7' has no spines whereas they are present on the reference varieties. The length of the fruiting period for 'NR7' is short whereas it is medium in length in the reference varieties.

Description:

PLANT: upright growth habit, many current season's canes, early to mid-season vegetative bud burst, fruit bearing only on previous year's cane in summer
VERY YOUNG SHOOT: no anthocyanin colouration at apex during rapid growth

CURRENT SEASON'S CANE: absent or very weak bloom, absent or very weak anthocyanin colouration, very short internodes, short vegetative bud
DORMANT CANE: greyish brown
SPINES: absent

LEAF: medium to dark green, predominantly three leaflets per leaf, concave profile of leaflets in cross section, medium rugosity between the veins, relative position of lateral leaflets overlapping
PEDICEL: no spines

BEGINNING OF FLOWERING: early
PEDUNCLE: no anthocyanin colouration
FLOWER: medium size

FRUIT RIPENING: beginning early in the season, short duration
FRUITING LATERAL: horizontal to drooping attitude
FRUIT: medium length, medium to broad in width, small length/width ratio, broad conical shape in lateral view, medium size of single drupe, medium red, weak glossiness, soft to medium firmness, weak to medium adherence to plug

Origin & Breeding History: 'NR7' arose as the result of crossing 'HR101' (seed parent) with 'Willamette' (pollen parent) as part of a planned breeding program of the New Zealand Institute of Plant and Food Research Limited in Motueka, New Zealand. The initial cross was conducted in a greenhouse in 1997 and the resulting seed was sent to Lynden, Washington, USA in 1999. A total of 120 seedlings were planted in the field in 1999. The original plant of the new variety was selected during the summer of 2001 and coded ZNH062. While not suited to commercial production, 'NR7' was selected for its compact growth habit for use in ornamental gardens.

Tests & Trials: 'NR7' was tested in Richmond, British Columbia during the 2012 growing season. The trials consisted of 4 replicates of the candidate and reference varieties. Plants were spaced 0.6 metres between plants in the row and 2 metres between rows. There was a minimum of 12 plants per variety. Measured characteristics were based on a minimum of 15 measurements.
