New research has been published about the influence of mother seed tuber size on yield and seedborne PVY.  Read about the findings in American Journal of Potato Research! 🥔Link in Bio!

'The complex association between powdery scab and Potato Mop-Top Virus (PMTV) creates a scientific agronomic puzzle that makes managing the 2 diseases difficult'. Read more about this in Potato Grower's September 2025 issue (Page 34)! Link in Bio!

Symptoms of virus can look similar in potato tubers. Always a good idea to have tubers tested. Unfortunately, this sample hit the trifecta! Tobacco Rattle Virus, Potato Mop top Virus and PVY-NTN. Many conditions to manage; but, our researchers are working to help minimize losses.

"Controlling PVY through resistant varieties can prove complicated." Read more about potato breeding resistance in Walter De Jong's Spudman article! Link in Bio!

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Look at these foliar symptoms of PVY! Alturas samples submitted for identification and information. Positive for PVY-NTN. Visit the website for more information. Link in bio!

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Found PMTV symptoms in my tuber! More information can be found here: https://t.co/4CkNM4v35F

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

No, this is not foliar symptoms of PMTV; but YES, foliar symptoms of foliar Alfalfa Mosaic virus. Visit our website for more information on potato viruses!

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

The PVY demonstration plots showed that certain varieties showed very strong symptoms when infected with PVYO, while others showed very little to no symptoms when infected with PVYO, PVYNWi and PVYNTN. Read more about it in our newsletter available at https://t.co/DVfHzlF5A1

Research at the University of Idaho is helping potato breeders make progress in their efforts to breed potatoes with resistance to all strains of PVY (Potato virus Y). Read more about our article on Potato Country's May/June 2025 Issue. Link in Bio!

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Read about the hands-on workshop held in Wisconsin to work on standardizing protocols for direct tuber test results between states. Read more about it in our newsletter available at https://t.co/DVfHzlF5A1

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Mop-Top is a virus that infects potatoes and causes the formation of a powdery scab. Kylie Grimm and Richard Quick wrote an article Potato Country's February 2025 issue discussing the impact this virus may have on commercial growers. Link in Bio!

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

On-going research to identify candidate genes for Ry-adg and testing whether these candidate genes confer resistance to #PVY.  Read more about it in our newsletter available at https://t.co/DVfHzlF5A1

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Potato virus Y remains the top 'most troublesome disease' for the potato industry. Luckily many scientists are still actively working to combat this issue. Read more about other concerning pests and diseases to watch for this year in Spudman April Issue. https://t.co/I4axdrVSAG "

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Molecular markers associated with resistance genes have been useful in rapidly identifying and incorporating PVY resistance into potato breeding clones having potential for release as new PVY-resistant potato varieties. Read more about it in our newsletter. Link in Bio!

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Payette Russet was deemed fully PVY-resistant or completely immune to PVY within the boundaries of the U.S. and even in North America. Read more about it in our newsletter available at https://t.co/DVfHzlF5A1

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Currently, complete resistance to PMTV does not exist in the widely grown russet varieties. Resistance to PMTV needs to be incorporated into new varieties but resistance to the virus and symptoms must be found. Read more about it in our newsletter. Link in bio!

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

A greenhouse assay to screen germplasm for PMTV and/or S. subterranea resistance was successfully generated at the USDA-ARS Prosser research laboratory. Read more about it in our newsletter available at https://t.co/DVfHzlFDpz

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Researchers are screening for PVY resistance! A higher number of resistant individuals with local and systemic resistance were observed and suggests that corresponding genetic region(s) will be identified. Read more about it in our newsletter! https://t.co/DVfHzlFDpz

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Research results support recommendations for PVY mitigation efforts to extend at least to onset of tuber bulking. Read more about it in our newsletter! Available at https://t.co/DVfHzlFDpz

[PotatoVirusInitiative:DevelopingSolutions @PotatoVirusIni1]

Greenhouse assays were developed to help to identify soils with powdery scab suppressive activity. Read more about it in our newsletter! (pg 23-24) Link in bio
