Monsanto uses a specialized breeding approach to develop corn hybrids that meet market and grower needs. This includes utilizing their large global germplasm pool and marker-assisted breeding technology. Their hybrids undergo extensive testing before commercialization to ensure strong performance and consistency across locations and years. Comparative trials show Monsanto's DEKALB Roundup Ready Corn 2 hybrids outyield similar maturity Pioneer hybrids by an average of 5.8 bushels per acre.

2. Monsanto Breeding Approach
• DEKALB hybrids are developed from one of the largest
global proprietary germplasm pools in the industry
• World-class science and the use of marker-assisted breeding
provides speed-to-market advantages:
– Genetic fingerprinting and germplasm characterization
– Millions of marker data points
– Genotypic selection
– Introduction of agronomic traits like Roundup Ready®,
YieldGard® Corn Borer, YieldGard Rootworm and YieldGard
Plus in new elite genetics
