Variety Description

Varieties used for comparison: 'HyRed' and 'Ben Lear'

Summary: 'NJS98-23' has larger leaves than the reference varieties. The berry of 'NJS98-23' is larger than the reference varieties. 'NJS98-23' has a higher mean berry weight than the reference varieties. Plot colonization, stolon growth and plot density of 'NJS98-23' are more vigorous than the reference varieties.


PLANT: semi-erect, early flowering period

LEAF: ovate shape, obtuse apex, truncate base, entire margin, leathery texture

FRUIT: ovate shape in longitudinal cross section, large size, weak bloom, dark purple red (RHS 46A) to brown purple (RHS 187A) colour, strong intensity of colour, early maturity

Origin & Breeding History: 'NJS98-23' resulted from the cross made in 1988 at Rutgers University, Chatsworth, New Jersey with 'Stevens' as the seed parent and 'Ben Lear' as the pollen parent. A single plant was selected in 1998 based on the following selection criteria: yield, fruit rot susceptability/resistance, scald, stolon and upright vigour, total anthocyanin content (TAcy), soluble solids and titratable acidity.

Tests & Trials: Tests and trials were established in 2000 in Richmond, British Columbia and were evaluated in 2006 and 2007. Plots consisted of fully established mats that were 4.6 meters by 4.6 meters in size with an approximate density of 30-40 uprights per decimeter squared which arose from stolons rooted along multiple points within the plot. There were 60 cm pathways between blocks and 3 replicates.
