Other claims from this paper (8)

Observation Golden cyst nematode larvae had shorter stylets than white and cream nematode larvae.
Observation Median bulb valve to excretory pore distance did not distinguish white and golden populations.
Intervention effect Resistance genes from S. vernei nearly eliminated cyst formation in golden populations.
Intervention effect Resistance genes from S. spegazzinii nearly eliminated cyst formation in golden populations.
Intervention effect Resistance genes from S. oplocense nearly eliminated cyst formation in golden populations.
Intervention effect Some S. oplocense and S. vernei clones strongly reduced cyst formation of certain white populations.
Observation Two named clones differentiated the two nematode species.
Observation Many white nematode pathotypes make breeding resistance more difficult than for golden nematodes.
