Objective:
The goal of this project is to develop a probabilistic risk-based model to assess the efficacy of seed quality management practices in reducing phytosanitary risks as well as enhancing disease control. The model will provide a method to quantitatively assess how individual steps in production practices reduce risks associated with seedborne pathogens.
Approach:
A qualitative guide to seed quality management practices was created by ASTA in July 2010. The document provides step-wise guidance for the development of quality management practices. The guide follows Hazard Analysis and Critical Control Points (HACCP) principles and includes eight modules that span the seed production pathway from incorporation of a trait into a breeding program through commercial seed production and sale. Individual seed production pathways vary considerably. The general breeding program could be conducted in a greenhouse, laboratory, and/or field setting. These can be considered branches in the pathway, each associated with their own individual phytosanitary risks and mitigation practices. The proposed model would allow us to examine each individual step in the production pathway as well as all branches (individually or as their proportional contribution to that step in the pathway) and examine the quantitative risk to each step as well as the overall production pathway.
