Plot production is used for the first multiplication of Breeder seed in Canadian seed certification for most non-hybrid annual crop kinds. Breeder seed is carefully multiplied by experienced plot growers to maintain the highest standards of varietal purity within pedigreed seed and in order to have sufficient Select or Foundation parent seed stocks for other seed growers to produce Registered and Certified seed of the variety.
How to become an accredited Plot Producer
Plot production is restricted to experienced CSGA Select growers. An individual seed grower wishing to produce Select and Foundation plots can obtain CSGA accreditation through the successful production of a series of probation plots. The applicant must receive permission from the CSGA and meet the requirements of the CSGA before commencing probation plot production. To become an accredited plot grower, the applicant must first complete a three year probation program in plot production. Before the probation period can begin, the grower must have produced pedigreed seed, of the crop kind they intend to produce during the probation period, in three of the last five years.
To commence probation plot production, please submit an Application to Commence Probation Plot Production to the CSGA office prior to March 31 for spring-seeded crops and July 31 for fall-seeded crops.
Pedigreed Seed Plot Production Quality Manual
Plot production regulations are outlined in this document and should be used in conjunction with the CSGA Regulations and Procedures for Pedigreed Seed Crop Production (Circular 6), which outlines the requirements for Select, Foundation, Registered and Certified seed crops.
Rogues and Roguing Manual
A rogue is any undesirable plant in a seed crop. Plot Growers are responsible for removing off-types and plants of other varieties and for keeping these variants at the minimum acceptable level. The Rogues and Roguing Manual provides information to seed growers on how to identify rogues (undesirable plants) and on roguing (removing them) from pedigreed seed crops.
Plot Production Forms and Documents
Report on Plot Production
All Select and Foundation seed production plots must submit a report on their plot production before certification can be completed. It allows CSGA to provide feedback to plant breeders on varietal characteristics such as stability and adaptability to the region where the plot is being produced.
Variety Verification Seed Samples
For variety verification testing purposes, plot growers must submit seed samples from Probation, Foundation and Select plots in to the CSGA. This support document provides instructions to plot growers on how to send variety verification seed samples to the CSGA.
