Verbatim
e0“In the absence of fungicide and with natural infections of stripe rust ( Puccinia striiformis f.sp. tritici ) and leaf rust ( Puccinia triticina ), Lr34res lines had lower disease severity, increased total yield, and better grain quality than Lr34sus lines.”

Other claims from this paper (6)
- Association Without fungicide, Lr34res lines yielded more than Lr34sus lines under natural rust infection.
- Association Without fungicide, Lr34res lines had better grain quality than Lr34sus lines.
- Association With full fungicide control, Lr34sus lines had higher mean plot yield in 2010 than Lr34res lines.
- Association With full fungicide control, Lr34sus lines had higher mean plot yield in 2012 than Lr34res lines.
- Association With full fungicide control, Lr34sus lines had superior grain quality to Lr34res lines.
- Recommendation The authors conclude Lr34 provides little or no competitive advantage in the current high-input New Zealand trial system with full fungicide control.
