Characteristics (Table 31, Figure 29) Plant: soft woody,<br />
upright stems, width medium, height tall (average158cm),<br />
branches present but mainly single stem, reddish<br />
anthocyanin pigmentation present, branch endings forked<br />
into three with terminal seed. Leaves: sessile, oval, 7 x 5cm<br />
in size, upper surface dark green, lower surface light green<br />
with a yellowish tinge. Flowers: stalk length 1.7–3.2 cm,<br />
green to yellowish with red-brown anthocyanin colour,<br />
flower size 2.7–3.5cm, 5 slightly asymmetrical sepals<br />
(calyx), 3 larger and 2 small; calyx broadly elliptical with a<br />
round top; size 16 x 8 mm, 5 slightly asymmetrical goldenyellow<br />
petals, approx. 1.3cm long with an elliptical concave<br />
appearance. Stamens: outwardly extending with dark<br />
brown-orange bilobed anthers. Pistil (stigma, style and<br />
ovary): pale greenish-yellow small ovary, 3 light green<br />
styles and dark red-brown stigmas. Fruit: size medium, 1.2<br />
cm long and 0.7 cm in diameter; shape at the apex pointed,<br />
high length to width ratio with visible strong lobbing; berry<br />
colour at picking deep red-brown (RHS 185A) with a dull<br />
weak glossy appearance.<br />
Origin and Breeding Controlled pollination: ‘Bosadua’<br />
was selected from controlled crossings between the seed<br />
parent Nr83 and the pollen parent Nr71 in a planned<br />
breeding program. Hybridisation was performed on the<br />
breeder’s property in Rijnsburg in the Netherlands in 1988.<br />
Several plants from the 1,500 resultant seedlings were<br />
selected in August 1989. In 1991 the final selection was<br />
vegetatively propagated to 250 plants and was checked for<br />
four years to ensure uniformity and stability. Selection<br />
criteria: flowering time, berry colour, shape and size.<br />
Propagation: by vegetative means. Breeder: B.R. van den<br />
Bosch, Rijnsburg, The Netherlands.<br />
Choice of Comparators Hypericum androsaemum<br />
‘Hippie’ was chosen as a comparator because it is the most<br />
similar variety of common knowledge and only known “cut<br />
flower” variety of the same species in <strong>Australia</strong>. A wild<br />
form of Tutsan (H. androsaemum) was collected from the<br />
wild at the time of harvest and certain berry characteristics<br />
were examined and compared. St John’s Wort (H.<br />
perforatum) is a different species and was not included in<br />
the trial. Four other candidate varieties from the same<br />
breeder were also included in the trial.<br />
Comparative Trial Comparators: ‘Hippie’, and wild<br />
Tutsan. Each of the candidates were compared against each<br />
other and also with the chosen comparators. Location:<br />
conducted at Clayton road farm of F & I Baguley at Clayton<br />
South in Victoria. Conditions: trial was planted into an open<br />
high roofed polyhouse. Rooted cuttings were planted<br />
directly into a pure sand soil amended with organic matter<br />
in Jun 1998 and assessed and harvested when the berries<br />
were at their maximum colour production for commercial<br />
sale in Jan 1999. The crop was irrigated by drip irrigation<br />
and fed hydroponically, the crop was sprayed at regular<br />
intervals to prevent fungal and insect damage. No growth<br />
regulators were applied. Trial design: four plots of 50m<br />
length were planted with the 5 test varieties and the one<br />
comparator in a randomised block design. Measurements:<br />
taken from 50 plants selected at random from within each<br />
trial block.<br />
