Guaranteed disease-free wheat seed arrives at El Batán
Workers at CIMMYT's El Batán, Mexico headquarters unload a consignment of wheat seed that has just arrived from CIMMYT wheat multiplication plots in Mexicali, northwest Mexico.
All the seed that CIMMYT sends out through the International Wheat Improvement Network (IWIN) international nurseries goes through a two-step multiplication process in fungicide-protected quarantine nurseries to ensure that it is free of the disease Karnal bunt. It is first planted at El Batán, where the resulting seed undergoes rigorous treatment and seed health assessment. It is then sent for quarantine multiplication in Mexicali. Mexicali is recognized by the Mexican Government, the North American Plant Protection Organization (NAPPO), and the European Plant Protection Organization (EPPO) as a Karnal bunt-free area. CIMMYT’s field plots in Mexicali are repeatedly treated with systemic fungicides, visually inspected, and sampled for more diagnostic pathogen testing. The seed then undergoes one more round of health testing at El Batán before being prepared for export.
