I want to know what seeds are used for food and vegetables in the United States, hybrid or transgenic, and which companies' seeds?

There are hybrids and transgenes, but the transgenic seeds will be clearly marked. (There are many genetically modified soybeans and corn seeds)

At present, the larger seed companies in the United States include:

1. Monsanto? (Monsanto? Company)

2. DuPont Company

3.? Lando Lake Company (Land? Oh? Lake? )
