‘AG Outback’
Application No: 2000/266 Accepted: 29 Aug 2000.
Applicant: Ag-Seed Research Pty Ltd, Horsham, VIC.
Characteristics (Table 10, Figure 31) Plant: habit erect,
height medium (120.1cm), early maturing. Seedling:
cotyledon narrow (width/length ratio 1.61), first true leaf
few to numerous hairs, 5th leaf lobbing mostly absent (5%
lobes), colour green (RHS 137C-D, 1986). Flower: narrow
petals (length/width ratio 2.3), anther dotting present. Pods:
short (43.4mm), pedicel short (19.7mm), beak short
(10.9mm). Seed: black, canola quality. Disease Resistance:
high blackleg resistance.
Origin and Breeding Controlled pollination: ‘AG
Outback’ was developed using a modified pedigree
breeding method in 1997 from a cross, made in 1996,
between seed parent, AGA95-1 and pollen parent
‘Monty’ A . The seed parent is a breeding line, which is
characterised by early to very early maturity, lower oil
content, poor blackleg resistance and the pollen parent is
characterised by early maturity, better oil content and better
blackleg resistance. Between 1997 and 1998 the cross was
evaluated for yield, blackleg resistance, oil and protein
content and canola quality in nurseries at Mininera and
Horsham. In 1999 the variety was entered into the Interstate
Stage 2 canola trials and then to Stage 4 trials in 2000, as
AGA99-4, and was trialled in a range of locations covering
relevant canola growing regions of Australia for two years.
Certified seed production occurred in 2000 and the variety
will be commercialised in 2001. Propagation: open
pollinated seed. Breeder: Ag-Seed Research Pty Ltd under
a team headed by Dr. Gururaj Kadkol.
Choice of Comparators ‘AG Emblem’, ‘Georgie’,
‘Mystic’ A and ‘Monty’ A were used as comparators. ‘AG
Emblem’ and ‘Georgie’ are recently released medium early
maturing canola varieties. ‘Mystic’ A and ‘Monty’ A are
established early maturity varieties in Australia. The seed
parent was not included because it is breeding line within
the breeding program.
Comparative Trial Location: Comparative trials were
conducted at Ag-Seed Research trial site at Horsham, VIC.
Conditions: Field trials were conducted during 2000 season.
Glasshouse trials were carried out in 2000 and 2001. Trial
Design: data on mature plant characters were collected in
replicated field trials consisting of six row, 5m plots laid out
as randomised blocks. Seedling character data were
collected in glasshouse trials designed as completely
randomised trials. Measurement: data were recorded on 20
random plants from each of the three replicates giving a
total of 60 observations per variety.
Prior Applications and Sales Nil.
