Germplasm Enhancement of Maize

Monsanto has provided long-standing (20 years) support to the USDA Germplasm Enhancement of Maize (GEM) program, through in-kind service in the form of approximately 2,000 yield trial plots and some nursery rows each year, and  by providing 1 to 2 elite (proprietary) lines per year for use as breeding parents. Selections from the resulting breeding populations will be made publicly available as “GEM” lines.

In term of contribution of private germplasm to the public sphere, it is also important to note that improved maize lines with expired PVP, while representing only 2% of the available material from the USDA Maize Genebank, accounted for 48% of the seed packets distributed globally in 2013, highlighting how valuable and utilized this improved germplasm has become all around the world.
