For consistency, botanical and common names should<br />

follow those of: Hortus Third, Staff of the LH Bailey<br />

Example 1<br />

Genus species<br />

Common name of the species<br />

‘Variety’ syn Synonym (if applicable)<br />

Application No: xxxx/xxx Accepted: dd month year.<br />

Applicant: Applicant’s Name, Town, State<br />

(abbreviation) and Country (if not <strong>Australia</strong>).<br />

Agent: Agent’s Name, Town, State (abbreviation).<br />

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 />
