Some exciting options are now available for farmers interested in growing triticale.
Trials conducted by Southern Farming Systems (SFS) near Geelong, Victoria, produced encouraging results from varieties sourced from the National Triticale Breeding Program based at the University of Adelaide, which is supported by growers and the Federal Government through the GRDC.
Two recently released lines, Credit and Treat, performed significantly better than Tahara, which is widely grown in the district.
Credit, a high-tillering variety, is very tolerant of waterlogging. Credit was standing quite well at harvest when both Tahara and Treat were starting to lodge, and according to SFS researcher Colin Hacking would possibly be the most suitable variety to grow under local conditions.
Treat returned a high test weight (average 6 kg/hi above Tahara). It matures a few days earlier than Tahara. (Abacus, a longer-season variety commonly grown in the district, was not included in the trial but will be included in the 2001 trial.) Researchers conducted their trials on raised beds to minimise waterlogging damage.
Varieties finding favour elsewhere are Muir, a stronger strawed variety which tolerates waterlogging and high winds and is popular in NSW and Kangaroo Island, and Everest, a taller variety with high test weight released by the University of New England.
All these varieties are resistant to leaf, stem and stripe rusts and mildew and have good resistance to root lesion nematodes, but all except Tahara and Tickit are susceptible to cereal cyst nematode (CCN).
Triticale is generally widely adapted, growing well on low to high pH soils and from low to high rainfall. Its tolerance to acid soils makes it worth investigating for south-west Victorian and similar environments. On the downside, triticale is sensitive to frost at flowering, although the risk of damage at flowering can be minimised by choice of seeding date, variety and maturity type and by staggering sowing dates.
