Numbering System for Burrus Corn Hybrids and Soybean Varieties



 The Burrus numbering system is designed to help growers identify maturity levels of different hybrids for comparison.  The Burrus numbering system indicates the maturity with the first digit.  Simply multiply the first digit by two then add 100 for the maturity day rating.  Using the example Power Plus® 4J95AMX™* brand, multiply the first digit 4 X 2 = 8 then add 100.  This depicts the maturity range as 108-109 day.  The letter has no particular meaning.  If the last two digits are above 50, add one more day.  So since Power Plus 4J95AMX™* is above 50, it is 109 days.  When the letter is the same and the digits are consecutive it indicates a similar family.


The soybean numbering system incorporates the first two digits to represent the maturity level.  The letter is random and the last digit represents the year that variety entered the lineup.  As an example, the Power Plus® 37N5™* indicates that this is a 3.7 maturity soybean that first entered the lineup for 2015 planting.
  If you have any questions about the numbering system for either corn hybrids or soybean varieties in the Burrus family of products just ask your local Burrus/Hughes dealer or one of our Account Managers.  At Burrus we strive to make product selection easier and more convenient for the grower.
