Characteristics<br />
Characteristics should be described in the following order:<br />
Plant, Stem, Leaf, Inflorescence, Flower and flower parts,<br />
Fruit and fruit parts, Seed, Other characters (disease<br />
resistance, stress tolerance, quality etc). Characters within<br />
subheadings should generally be in the following order:<br />
habit, height, length, width, size, shape, colour (RHS colour<br />
chart reference with edition), other. Use a concise<br />
taxonomic style in which subheadings are followed by a<br />
colon and characters are separated by a comma. Where<br />
there is a UPOV technical guideline available make sure<br />
that the asterisk characteristics are included in the<br />
description.<br />
Example 2<br />
Characteristics (Table nn, Figure nn) Plant: habit<br />
narrow bushy, height medium, early maturing. Stem:<br />
anthocyanin absent, internodes short. Leaf: length long,<br />
width narrow, variegation present, predominant colour<br />
green (RHS <strong>13</strong>7A), secondary margin colour pale greenyellow<br />
(RHS 1A). Inflorescence: corymb. Flower: early,<br />
pedicel short, diameter small (average 12.5mm), petals<br />
5, petal colour yellow (RHS 12A), sepals 5 …..etc<br />
(Note: give the reference for the edition of RHS colour<br />
chart used, eg. all RHS colour chart numbers refer to<br />
1986 edition)<br />
Origin and Breeding<br />
Indicate how the variety was originated, ie. controlled<br />
pollination, open pollination, induced mutation,<br />
spontaneous mutation, introduction and selection, seedling<br />
selection etc. Give the name of the parents. Also give the<br />
characteristics of the parental material by which they differ<br />
from the candidate variety. Briefly describe the breeding<br />
procedure and selection criteria used in developing the new<br />
variety. Also indicate the mode of propagation used during<br />
breeding. Give the name(s) of the breeder.<br />
Example 3<br />
Origin and Breeding Controlled pollination : seed<br />
parent S90-502-1 x pollen parent S90-1202-1. The seed<br />
parent was characterised by early flowering, dark green<br />
non-variegated leaves and compact bushy habit. The<br />
pollen parent was characterised by late flowering,<br />
variegated leaves and narrow bushy habit. Hybridisation<br />
took place in , in . From<br />
this cross, seedling number S 3736 was chosen in 1993<br />
on the basis of flowering time. Selection criteria:<br />
variegated leaves, compact bushy habit and early<br />
flowering. Propagation: a number mature stock plants<br />
were generated from this seedling through tissue culture<br />
and were found to be uniform and stable. The ‘Variety’<br />
will be commercially propagated by vegetative cuttings<br />
from the stock plants. Breeder: , ,<br />

Example 4<br />
Origin and Breeding Introduction and selection: 5<br />
cycles of selection within <br />
originating from and supplied by<br />
the under a materials transfer<br />
agreement. When grown CI2204 was heterogeneous<br />
with both hooded and non-hooded types and differences<br />
in seed colour. Repeated selection for hooded types<br />
produced seven breeding lines (726.1-726.7) which were<br />
evaluated for forage and seed production potential. From<br />
these lines, an uniform single line known as 726.2.1 was<br />
selected to become ‘Variety’. Selection criteria: seedling<br />
vigour, dry matter yield, uniformly hooded (awnless),<br />
seed colour (black). Propagation: by seed. Breeder:<br />

Choice of Comparators<br />
As choosing the most appropriate comparators may be the<br />
most crucial part of the trial, we suggest the QPs do more<br />
research and record their decisions before making the final<br />
selection. Under this heading briefly indicate what factors<br />
you have considered in choosing the comparator(s) for the<br />
trial. It is strongly recommended that the parental materials<br />
or the source germplasm is included in the trial for<br />
comparison purposes. If the parents are excluded indicate<br />
the reason(s).<br />
Example 5<br />
Choice of Comparators ‘Comparator 1’, ‘Comparator<br />
2’ and ‘Comparator 3’ were initially considered for the<br />
comparative trial as these are similar varieties of<br />
common knowledge. ‘Comparator 1’ is a widely<br />
available commercial variety of the same species,<br />
however it has non variegated leaves. Therefore it was<br />
excluded from the trial. ‘Comparator 2’, was chosen for<br />
its variegated leaves and ‘Comparator 3’ was chosen for<br />
its compact growth habit and variegated leaves. The<br />
parents were not considered for the trial because the<br />
‘Variety’ is clearly distinguishable from the seed parent<br />
by its variegated leaves and from the pollen parent by<br />
flowering time and growth habit.<br />
