Koedoes: A ϐlagship irrigation
wheat cultivar for the ARC-SGI
As majestic as a Kudu bull in the wilderness – this is Koedoes,
the new cultivar in the ARC-Small Grain Institute’s
(ARC-SGI) trials and it will be cultivated on a commer-
cial scale.
This cultivar has already been approved by the industry and current-
ly the ARC-SGI is in the process of obtaining plant breeders’ rights
to be able to commercialise the cultivar. A suitable marketer will be
appointed after a tender process at the end of 2015 and the cultivar
will then be commercially available for the irrigation areas in 2017.
The cultivar is a high yielding cultivar and we at the ARC-SGI are
confident that it will become one of the leading cultivars in the
irrigation areas. During the 2013 season, Koedoes compared very
well with the cultivar Krokodil with yields of up to 10,6 tons/ha.
Koedoes’ yield potential is also higher than both Sabie and Duzi.
In the cooler irrigation areas, Koedoes had an average yield of
9 tons/ha and in the warmer irrigation area 9,4 tons/ha. The major
difference of Koedoes from the current cultivars in the irrigation
cultivar package of the ARC-SGI, is its short growing season (ten
days earlier), making it more desirable for producers with a specific
crop rotation system and water availability in the different irriga-
tion schemes.
The falling number can however be affected if the cultivar is
still irrigated after maturity, but still safe above 250 min for down-
grading. The cultivar also has a good
hectolitre mass, with an average
of 79 kg/hl.
The cultivar has a normal straw length
and like all the cultivars in the irrigation
cultivar packages of the ARC-SGI, it
has good baking quality. Often culti-
vars with a short growing season
struggle to compete with yield against
medium growth period cultivars, but
the cultivar has the potential to com-
pete with these cultivars and can even
exceed the current cultivars with
yield, if the correct management is
applied. Koedoes is therefore a good
replacement for the old short growth
period cultivar, Steenbras; this will
enable producers to realise high yields
in a shorter growth cycle.
We are looking forward to the commer-
cialisation of Koedoes and are positive
that this short growing
season cultivar will be
a force to be reckoned
with.
