Project Type: Non-Assistance Cooperative Agreement
Start Date: Sep 1, 2008
End Date: Aug 31, 2013
Select potato germplasm resistant to two pathogens, a leafhopper vectored phytoplasma which causes purple top and an oomycete that incites late blight.
Tuber families will be sent to PICTIPAPA from various sources in the the US. These will be planted out in field plots in Metepec, Mexico under the supervision of Hector Lozoya Saldana. Obvservations on foliar damage due to Phytophthora infestans and Purple Top Phytoplasma will be recorded. At harvest, selection will be based on field notes and tuber yield and type. Tubers will be retained during the off-season and re-planted the following growing season. Documents SCA with Universidad Autonoma Chapingo.
