The Corn Journal

Perspectives on corn biology, genetics, seed, breeding, and disease by Jim Dodd.

The Corn Journal preserves a collection of practical observations developed through decades of work with corn. The archive combines technical and accessible explanations for seed-industry professionals, researchers, growers, and anyone interested in the biology of Zea mays.

The original articles are being organized here as a permanent part of the Professional Seed Research website.

Genetics & breeding

How corn became a hybrid crop

Articles covering inbreeding, heterosis, genetic diversity, populations, and the development of modern corn hybrids.

Plant biology

Inside the corn plant

Accessible explanations of meristems, stomata, roots, water movement, flowering, maturity, and grain development.

Disease & stress

Understanding plant health

Observations on root and stalk rots, premature death, tar spot, pathogens, environmental stress, and standability.
