Standardizing Identification of Plant Pathogen Strains in Vegetable Seed Industry

 
A science-based, vegetable seed industry initiative to
standardize the identification of plant pathogen strains and
races based on sets of host differentials and reference
plant pathogen strains
 
CPPSI Update: January 27, 2018
 
CPPSI @ UC Davis
 
Final year of the initial three year funding commitment from
Founding Sponsors
CPPSI Advisory Council meetings twice a year during the ASTA meetings
held in June and January
CPPSI Working Group meets monthly via web conference
 
Business Plan updated and approved by Advisory Council
Continued development of Reference Materials
Expanded roles: ISF DRT WG, Harmores 3, Melon PM WG, Emerging
diseases website only available to CPPSI members
New CPPSI membership model based on annual revenue; similar to ASTA
and CSA membership models
Focus on sustainability through new & renewed memberships, grants,
service opportunities
 
CPPSI @ UC Davis
 
Secured commitments from all Founding Sponsors to renew
3 year memberships
 
Awarded CDFA SCBG funding for 2.5 years in support of
continued CPPSI growth
$340,000
1 Nov 2017 – 31 Mar 2020
 
Waiting on final UC Davis approval to start charging
nonmembers for differentials and reference strains
‘One Stop Shopping’ service
Can still access differentiating hosts from the USDA via GRIN
Coordinate with the launch of the round 2 Reference Materials
 
February issue of Seed World – feature article on CPPSI
 
Reference Material Development
 
CPPSI WG and Advisory Council selection and approval
Schedule seed increases
Phytosanitary and functional testing
Identify and secure source(s) of reference strains
Storage, inoculation, evaluation and distribution protocols approved by CPPSI
WG
Comparative testing with GEVES, Naktuinbouw
Develop white paper
Material Transfer Agreements where needed
Deposit Reference Materials for distribution
Announce availability on 
www.cppsi.org
Review and update white papers, check strain viability and replenish
reference materials as needed

Focused on standardizing plant pathogen strain identification, the CPPSI initiative by UC Davis works towards enhancing the industry's capabilities. Through reference materials and strategic collaborations, CPPSI aims to streamline disease management processes and promote sustainability. The project involves securing funding, developing membership models, and progressing in reference material development for various plant diseases. CPPSI is at the forefront of facilitating information exchange and technological advancements in the vegetable seed sector.
