top 5 from the top 8

Seed companies relate their top hybrids for the 2000 corn crop.

Wondering what to buy for hybrids this spring? We went to the top eight seed corn companies in the U.S. (based on our reader surveys) and asked for each of their top five hybrids for 2000. Then we compiled the following descriptions of each company's hybrids. Maybe you'll find something new, or maybe this will confirm your choice.

A word of caution: Most companies expect to sell out of their top hybrids.
