Hybrid Naming System

Corson Maize sources maize hybrids from over ten international seed suppliers. As a result of our diverse global supplier base, we had adopted a wide range of maize hybrid names and identification systems. However, recent grower and retailer feedback sought a simplified and easier to understand approach to naming these maize hybrids.

Following on from this, a new standardised identification system for Corson Maize hybrids was introduced in 2022. All hybrid names in the Corson Maize range now follow the PAC naming system already utilised for a number of our hybrids. The names of some existing hybrids have been updated to align under this framework. These changes are outlined in Table 2 to help you identify your favourite Corson Maize hybrids under the new naming system.

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 hybrids identified within our range as also suitable for growing on dairy platforms are identified as a hundred series under the PAC naming system (i.e. PAC 100 through to PAC 500) with one available in each plant maturity range. 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.
