Sunflower Variety Performance Trials

Oil

Oil type sunflowers are used for birdfood, oil crush and de-hull. Plant population and environmental conditions will have a significant impact on yield and quality attributes.

Non-Oil

All sunflowers varieties listed are susceptible to sclerotinia and sunflower rust strains present in Manitoba. Genetic resistance to verticillium wilt is rated as moderately susceptible to moderately resistant for all sunflower varieties presented. Plant population and environment will contribute greatly to the final product.

IMPORTANT NOTES FOR THE SUNFLOWER VARIETY PERFORMANCE TRIAL TABLES

• CV = COEFFICIENT OF VARIATION:A measure of the random variation in a trial. A smaller CV value is more desirable.

• LSD = LEAST SIGNIFICANT DIFFERENCE:Hybrids must differ by the LSD to be considered significantly different from one another.

• SIGN. DIFF. = SIGNIFICANT DIFFERENCE:Indicates if a real difference exists between hybrids at an individual location.

• Oil TypesNS=NuSun;
  HO=High Oleic;
  CO = ConOil

• TraitsCL = Clearfield tolerance;
  ExSun = Express tolerance;
  DM = Downy Mildew Resistance.

• Test weights reported in lbs per Avery (Canadian) bushel.

• Physiological maturity for sunflowers is R9, where the bracts on the head are almost completely brown.

• Totals for % seed sizing may not add to 100% due to rounding.
