Mangifera indica
Mango
‘B74’
Application No: 1998/018 Accepted: 30 Jan 1998.
Applicant: The State of Queensland through its
Department of Primary Industries, Brisbane, QLD and
Promised Land Avocado Pty Ltd, Childers, QLD.
Characteristics (Table 23, Figure 35) Tree: open, upright,
vigour low to moderate, fruit maturity season mid-late.
Young expanding leaf: strong red anthocyanin present.
Fully expanded leaf: smooth, length medium (mean
204mm), width medium to broad (mean 62mm), low
length/width ratio (mean 3.5), horizontal attitude, medium
petiole (40mm), shape elliptic with acuminate tip and acute
base, concave cross section, apical curvature of midrib,
blade not twisted, leaf edge not undulated, terpenolene
aroma present when crushed. Fruit: mid-late season
maturity, length medium (mean 101.3mm), width medium
(mean 91.3mm), length/width ratio medium (mean 1.1),
shape ovate, cross section broad elliptic, stalk cavity
shallow, sinus absent, bulge proximal stylar scar absent,
skin develops high levels of red anthocyanin where sunexposed,
flesh firm when ripe, texture smooth with low
fibre, flesh colour pale yellow. Sap exudation at harvest
with sap burn and skin browning. Fruiting characteristic is
bunch bearing with 2-4 fruits commonly carried on each
inflorescence. Seed: small, monoembryonic.
Origin and Breeding Controlled pollination between seed
parent ‘Sensation’ x pollen parent ‘Kensington Pride’
followed by seedling selection. Seedlings from controlled
pollinations were established on the property of Mr & Mrs
J.W. Dorrian at Childers, QLD and the candidate selected at
the fruiting stage. Selection criteria: precocious, heavycropping,
upright tree, with red-skinned, medium-sized,
terpinolene-flavoured fruit. Propagation: monoembryonic
cultivar vegetatively propagated by grafting on to seedling
rootstocks. Breeder: Queensland Department of Primary
Industries, Brisbane and Mr J.W. Dorrian and Mrs J.R.
Dorrian, Childers, QLD.
Choice of Comparators ‘Kensington Pride’ was chosen, as
it is the pollen parent of the candidate while ‘R2E2’ was
chosen as the variety of common knowledge most similar to
the candidate. In addition, ‘Kensington Pride’ and ‘R2E2’
are the most common varieties grown in Australia. The seed
parent ‘Sensation’ was not included in the trial because it is
quite distinctive to the candidate. For example, the mean
fruit size of ‘Sensation’ is smaller (360 g) than the candidate
while the skin colour is bright yellow (background) with a
dark red to purple blush that covers most of the surface.
‘Sensation’ is a very late variety, maturing 3-4 weeks later
than the candidate. ‘Sensation’ has no distinguishable
terpinolene smell (leaves) or flavour (fruit).
Comparative Trial Location: Childers, QLD 1997 – 2001.
Conditions: scions of the candidate and comparator
