Variety Description
Variety used for comparison: 'Yojuneau' (Juneau White)
Summary: The plants of ‘CIDZ0112' are shorter than those of ‘Yojuneau'. The lowest lateral sinus on the leaf of ‘CIDZ0112' is of medium depth while that of ‘Yojuneau' is deep. The flower head of ‘CIDZ0112' has fewer ray florets than that of ‘Yojuneau'.
Description:
PLANT: bushy type, upright to semi-upright growth habit, medium density branching
STEM: green
STIPULE: small to medium size
PETIOLE: moderately upwards to horizontal attitude
LEAF: medium to high length to width ratio, short to medium length terminal lobe relative to leaf length, obtuse base, weak glossiness of upper side, medium to dark green upper side, medium to many medium depth indentations of margin
LOWEST LATERAL SINUS: medium depth, margins either parallel or touching
FLOWER BUD (OUTER SIDE): white (RHS NN155D) just before opening
FLOWER HEAD: semi-double daisy type, few rows of ray florets
RAY FLORET: ligulate type only, attitude of basal part is moderately ascending to horizontal, two keels on upper surface, short corolla tube, flat to weakly convex in cross-section at widest point, weakly involute rolling of margin at basal quarter, reflexing along longitudinal axis with weak curvature along the distal quarter, medium to high length to width ratio, tip is rounded, emarginate or mamillate shaped tip
RAY FLORET (INNER SIDE): one colour, white (RHS NN155C), colour is similar compared to outer side
DISC: small diameter relative to head diameter, slightly domed in cross-section, green with no dark spot at centre before anther dehiscence, yellow orange at anther dehiscence
Origin & Breeding History: 'CIDZ0112' originated from a controlled cross conducted between two proprietary breeding lines, the female parent variety designated ‘B5550' and the male parent designated ‘B8463', conducted in Gilroy, California, USA in August 2013. The resulting seed was sown in May 2014. A single unique seedling was selected in October 2014 based on its flower type and colour, as well as its flowering response time.
Tests & Trials: The comparative trial for ‘CIDZ0112' was conducted in a greenhouse in St. Catharine's, Ontario in the summer of 2025. Fifty unrooted cuttings were planted into 15 cm pots, with 5 cuttings per pot, 10 pots per variety on June 30, 2025. Plants were pinched on July 14, 2025 prior to short day treatment. Plants were spaced 30 cm apart on July 21, 2025. Observations and measurements were taken from 10 plants, or parts of plants, of each variety on September 10, 2025. Mean differences were significant at the 5% confidence probability level based on a paired Student's t-test. Colour determinations were made using the 2015 Royal Horticultural Society (RHS) colour chart.
