SY Transformer Feed Barley

SY Transformer product logo

• Highest yielding commercially available spring barley in FAR CPT trials
• Suited to all sowing times and conditions in both the spring and autumn
• Good all-round disease resistance profile especially mildew and net blotch
• Large grain, average test weights and very low screenings


From the proven Syngenta spring barley breeding programme, SY Transformer has been developed in New Zealand in conjunction with Cropmark Seeds Ltd as head licensee and PGG Wrightson Grain (PGW Grain). SY Transformer is a spring barley with very high yield potential that is suitable for feed. Malting and distilling end uses are unknown and currently being investigated. It has an intermediate maturity and can be planted late or under dryland but has high yield potential with irrigation and appropriate inputs.


SY Transformer has high yield potential under all environments but has excelled under ‘normal’ conditions where it yields more than other barleys. It is the highest yielding variety in both the FAR autumn and spring sown trials when looking at the 4 year means showing consistency across years and environments.

Time of drilling

SY Transformer has proven itself in autumn and spring conditions so has a wide sowing window from May right through to late October and beyond. Growing conditions and yield potential always dictate PGR requirements and even though SY Transformer has a stiff straw it will benefit from a moderate PGR programme especially in the autumn and in very high growth environments.

SY Transformer has an intermediate development rate for harvest maturity.

Seed rate and tillering characteristics

SY Transformer is a medium to high tillering variety and target plant populations should be within the standard PGW Grain barley seed rate guidelines. Work done by Cropmark has shown yields are maximised by targeting 175-200 plants/m2 in the autumn.

Soil type, rotation and geography

SY Transformer can be planted on all soil types where barley is already grown and can be grown as a first or second-year cereal. As a second-year cereal, barley is generally more take-all tolerant than wheat, however, yield will be lower than a first-year barley crop.

Disease resistance

SY Transformer has intermediate resistance to scald and leaf rust and is mostly resistant to net blotch and powdery mildew. Considering this disease profile, SY Transformer will need a medium fungicide programme to focus on Scald, leaf rust and Ramularia from autumn sowings and leaf rust from late spring sowings. Please contact your local PGW Representative for site specific recommendations.

Straw strength and height

SY Transformer is a medium height cultivar with moderate to stiff straw. Autumn sowings, will require a robust PGR investment, especially under irrigation. In spring, this cultivar will still require a moderate to high PGR programme to prevent brackling and maintain high yields. The actual programme is determined by a combination of local conditions, management and yield potential. As with any cultivar, do not apply PGR if the crop is under any form of stress. Please contact your local PGW Representative for site specific recommendations.
