Even though most of the 2019 crop is still in the ground, it’s not too early to start thinking about 2020 and getting your seed shopping list finalized.

American Agriculturist asked top seed companies for their “top 5” corn and soybean varieties for 2020. These are varieties geared to Northeast and Mid-Atlantic farmers.

Below is a list of companies that have responded to our second request for top varieties. We’ll update it further as more companies reveal their top choices.

If you have any questions on a particular variety, contact your local seed dealer or email American Agriculturist at [email protected].


1. A2448-3220GTEZ (98 RDM). A high-yielding early line of corn from that was bred with Eastern agronomics at heart. It has a flex ear type, so the optimum planting population is between 24,000 and 36,000. It will have very good grain quality on a medium tall stalk.

Due to its size as well as its excellent feed value, it is recommended as an early dual-purpose hybrid. 

2. A4858-3010GT (108 RDM). A high-yielding hybrid with excellent test weight recommended for well-managed ground.

Due to its semi-flex ear, optimum planting should be in the 26,000 to 38,000 range. It will have good stay-green and has very good tolerance to gray leaf spot.

3. A1059-3330GTEZ (109 RDM). A variety with outstanding roots and stalk strength. It will hold its greenlife late into the season, and the plant tends to stay intact. 

Widely adaptable, A1059 brings top-of-the-line gray leaf spot and Northern corn leaf blight tolerance. Look for this plant to be available with Viptera 3330, one of the newest trait stacks in the Agrisure portfolio that features three modes of action against above-ground insects.

4. A5264-3000GT (114 RDM). A5264 takes a big, robust plant and brings the ear placement down to a medium level.

It has very good stalks and excellent stay-green. Grain quality and test weight are well-above average with excellent yield potential.

5. A4565-3220GTEZ and A4565 DC5222EZ (115 RDM). Girth, girth and more girth.

A4565 is an excellent choice for high populations — 28,000 to 38,000 depending on soil type.

This hybrid is available as Duracade 5222, which provides a unique mode of action to control above- and belowground insects and preserve the yield potential of elite corn hybrids.
