Faba Bean
FABA BEAN
There are varying sizes of faba bean seeds and colour that
are identified by different names. Small-seeded types (Vicia
faba var. minor) may be called faba bean or tickbean and
are commonly used for human consumption and animal
feed. Medium and large size seed types (V. faba var.
major) may be called broad bean and are used more
commonly as a dry broad bean or as a green bean.
Faba beans grown in Australia are predominately exported
for the human consumption export market to the Middle
East. These markets demand high visual quality standards
to meet market specifications in a relatively small world
export market. Australia competes with the European
Union, particularly the United Kingdom and France, for a
share of the 300,000 tonne Middle East market. Middle
Eastern countries use faba bean for human consumption
as part of the staple diet. It is referred to as ‘foul’ which is
equivalent to bread as a staple in Australian diets.
The market demand for the Middle East is consistent and if
there is a surplus of product produced in Australia, expect
to see a price decrease.
REVIEW OF 2014
Season
The good opening rains, sunny days and mild growing
conditions into winter gave faba beans an excellent start. In
the latter half of winter cooler dry conditions and frosts
slowed growth but also substantially reduced aphid
populations.
With dry conditions and strong winds in early spring faba
beans failed to realise their potential. A late frost in
November caused flowers to abort and pods to burst in the
southern Wimmera and south west regions.
Faba beans in the North East did well with excellent quality
and average to above average yields. Those on irrigation
also fared well. Some crops in the northern Mallee on
stored moisture from summer rain performed well as they
matured before the hot weather. Elsewhere yields varied
from below to well below average.
Quality was generally good overall.
The total area sown to faba bean is continuing to see a
resurgence, with improved understanding of agronomy and
disease management along with excellent commodity
prices. In recent years some growers using wide row, no-till
cropping have found faba beans profitable as the lower
pods are able to fill properly.
Disease and insects
Rust and chocolate spot were observed over late winter
and treated with fungicides, but as conditions dried off
fungal diseases did not develop.
A change in the ascochyta pathotype in the mid-north of
South Australia this year meant some resistance in the
faba bean genetics was overcome, but this pathotype did
not reach Victoria during 2014.
The warm start to the growing season increased the
number of insects and the potential for viruses. Again frosts
and drier conditions meant this did not continue except for
68
Victorian Winter Crop Summary 2015
some sporadic insect damage. However there could be
some seed staining from Pea seedborne mosaic virus.
LOOKING FORWARD TO 2015
New varieties
PBA Samira is the first of a new series of high yielding faba
beans to be released. These lines are expected to offer
yield advantages of 5-10% in most regions. Samira is
suited to the longer season environments and is expected
to replace Farah and Fiesta.
Pod set
Sowing early does not necessarily result in greater pod set,
but wider row spacings may help sunlight to penetrate the
canopy and increase podding. Sow in areas away from
canola paddocks to avoid bees being diverted to the
stronger odour of the canola. Sow away from field pea
crops to minimise aphid transmission of viruses, particularly
pea seed borne mosaic virus (PSbMV).
Disease
Growers need to be prepared for a shift in virulence as the
new strain of ascochyta spreads from South Australia to
Victoria. All varieties should be monitored carefully.
If 2015 provides good sowing conditions and adequate rain
during the grain fill period, it is highly recommended that
growers spray bean crops for disease control. The 6-8
week and 15 week growth stages are the important timing
to minimise ascochyta blight, cercospora leaf spot and
chocolate spot in order to maximise yield and harvest
disease free seed. Prompt harvest when the crop is initially
ripe is also important to retain grain quality. Anecdotally,
Aquadulce and PBA Kareema rated better for chocolate
spot resistance compared to Nura and Farah.
All current varieties are susceptible to cercospora leaf spot.

Broad bean - AQUADULCE
Tall late flowering broad bean with some tolerance to
waterlogging as well as iron and manganese deficiencies.
Best suited to high rainfall districts (>450mm). MS to
ascochyta blight, chocolate spot and rust. Released 1982.
Faba Bean
Broad bean - PBA KAREEMA
PBA Kareema is a direct replacement for Aquadulce. PBA
Kareema requires a long growing season similar to
Aquadulce and rainfall greater than 450mm. It is RMR to
ascochyta blight and MS to chocolate spot. PBA Kareema
is only recommended for the south west region of Victoria.
Released 2009. PGG Wrightson Seeds. EPR $4.
Faba bean - PBA RANA
Relatively late flowering and maturing variety suited to
higher rainfall, long season regions. Seed is larger than
current varieties and is considered high quality by the major
Egyptian market. Resistant to both foliar and seed
ascochyta blight with improved resistance to chocolate spot
compared to Fiesta and Farah. Seednet. EPR $3.50.
Faba bean - FARAH
Farah is similar to Fiesta but has good ascochyta blight
resistance (both leaf and pod), which reduces grain
staining from ascochyta at harvest. Farah yield is similar to
Fiesta across southern Australia and performs best in
medium rainfall environments. Released 2004. Heritage
Seeds. EPR $3.
Faba bean - PBA SAMIRA
A new higher yielding variety with wide adaption. Excellent
disease resistance and later flowering mean it can take
advantage of late rainfall in longer season environments.
Seed is a similar size to Fiesta and Farah and is suited to
Middle East markets. Excellent ascochyta resistance and
improved resistance to chocolate spot and rust compared
to Fiesta and Farah. Developed by PBA (as AF05069-2).
Released 2014. Seednet. EPR $3.50.
Faba bean - FIESTA VF
A medium sized bean, Fiesta has good yields and wide
adaptation throughout southern Australia. It has good
seedling vigour and is of medium height. Fiesta is MRMS to
foliar ascochyta blight, MS to seed ascochyta and S to
chocolate spot. Released 1998.
POTENTIAL NEW VARIETIES from Pulse Breeding
Australia.
Faba bean – AF05095-1
A new higher yielding breeding line. A later flowering and
maturing variety that has performed very well in longer
season environments. Seed is larger than Fiesta and Farah
and similar to PBA Rana and should be suited to Middle
East markets. Good overall response to diseases,
provisionally rated as resistant to Ascochyta and chocolate
spot. Developed by PBA. Release anticipated in time for
the 2016 growing season. Seednet. EPR to be determined.
Faba bean - NURA
Nura is shorter than Fiesta and Farah and less likely to
lodge, however the bottom pods are closer to the ground.
RMR to ascochyta blight, MS to chocolate spot and rust.
Nura needs to be sown early as it flowers about seven
days later than Fiesta, but it matures at a similar time.
Released 2005. Seednet. EPR $3.
