Applicant: Deltapine Australia Pty. Ltd, Narrabri, NSW.
Description (Table 8, Figure 36) Plant: tall, late maturing,
shape conical, foliage density medium. Leaf: palmate, size
medium (131mm x 98mm), pubescence of leaf veins
moderate. Gossypol and nectary glands present. Fruiting
branches: above node 6, internode length between 1st and
2nd fruiting positions long. Flower: petals cream. Boll: size
medium (45mm x 32mm), elliptic; peduncle length medium
(19mm), bract size medium (46mm x 23mm); boll opening
strong. Fibre: lint turn-out high (38.2%), length medium
(1.15in), strength medium (29.6), uniformity index medium
(81.7%) micronaire value medium (4.0). Bacterial blight
resistant, verticillium and fusarium wilt tolerance moderate.
Origin Controlled pollination: ‘DP 5816’ x ‘Sicala 34’ A .
Breeder: Mr. Richard Leske, Deltapine Australia,
Goondiwindi, QLD. Selection criteria: plant habit, bacterial
blight resistance, yield and fibre quality.

34’ A . Location: “Mundine” Goondiwindi, QLD, 1996-
1997. Conditions: fully irrigated, commercial herbicide and
fertiliser rates applied, 9 insecticide applications. Trial
Design: Randomised block with 4 replicates.
Measurements: morphological measurements from 25
plants per replicate. Lint percentage and fibre quality data
from replicated trials in 1995/1996 and 1996/1997.
