TALL WHEATGRASS
Thinopyron ponticum
‘Dundas’
Application No: 97/133 Accepted: 24 June 1997.
Applicant: Agriculture Victoria Services Pty Ltd,
Melbourne, VIC.
Characteristics (Table 28, Figure 45) Plant: bushy. Height
in spring: tall (170.9cm). Leaf: length average (27.6mm),
width average (7.3mm). Inflorescence: length average
(38.8cm), number of spikelets per spike low (75.3).
Origin and Breeding Phenotypic selection: plants were
selected from the tall wheatgrass variety ‘Tyrell’ based on
phenotypic selection. Syn I seeds were produced from 58
cloned genotypes after 4 genotypes were rouged as offtypes.
‘Dundas’ was developed as a leafy, productive
alternative to the existing variety ‘Tyrell’. Selection criteria:
plants were selected on the basis of leafiness, productivity
and disease resistance over 3 years. Propagation: by seed.
Breeder: Kevin Smith, The Pastoral and Veterinary Institute,
Department of Natural Resources and Environment,
Hamilton, VIC.
Choice of Comparators ‘Tyrell’ was chosen because it is
the only variety of common knowledge of tall wheatgrass in
Australia. ‘Tyrell’ is also the parent of the candidate variety.
Comparative Trial Comparator: ‘Tyrell’. Location: The
Pastoral and Veterinary Institute, Hamilton, VIC (Latitude
37 44´, Longitude 142 01´) spring – summer 1997/98.
Conditions: plants grown from seed in seedling trays in a
glass house and transplanted into the field at week eight.
Trial area fertilised at transplanting with 200kg/ha of an
NPK compound ferterlizer. The row component of the trial
was sown as seed directly into the field area. Trial design:
eighty single spaced plants of each variety were arranged
into eight replicates in a completely randomised block
design. The row component of the trial consisted of 10
meters of row for each variety arranged into two completely
randomised replicates. Measurements: carried out on each
individual spaced plant.
