Other claims from this paper (5)
- Observation Aphid transmission from yellowed sugar beet leaves revealed two yellowing viruses.
- Observation Sugar beet yellows virus produced vein‐etch and yellowing symptoms on beet seedlings in the glasshouse.
- Observation The other virus produced yellowing but no etch in beet seedlings.
- Observation The two yellowing viruses appeared unrelated, so tolerance to one did not imply tolerance to the other.
- Intervention effect Sugar beet mild yellowing virus reduced sugar beet root yield as much as milder SBYV strains, but less than severe strains.
