Corson Maize sources maize hybrids from multiple international seed suppliers. In order to understand how this wide variety of maize hybrids relate to each other we have adopted a simple naming system

All hybrid names in the Corson Maize range follow the PAC naming system (originally from Pacific Seeds). 

Under this system, a hybrid will be identified by the letters ‘PAC’ followed by three numbers. The first number denotes the plant maturity range for the hybrid and the following two numbers are its assigned identification. The Corson Maize hybrid maturity ranges are rated from 1 through to 6, 1 being a short maturity and 6 being a long maturity. Refer to Table 1 for a clear understanding of how it relates to the industry standard comparative relative maturity (CRM).

For example, PAC 430 is a hybrid identified as having a plant maturity category equivalent to 105-109 CRM. PAC 430 falls within this plant maturity range with a 108 CRM. The last two numbers ‘30’ refer to its identification.
