Sources and Inheritance of Resistance to Anthracnose Stalk Rot of Corn

Stalk rots are some of the more important diseases of dent corn (Zea mays) in the Midwest. In recent years anthracnose leaf blight and stalk rot, caused by Colletotrichum graminicola, have increased in prevalane in the warmer, humid corn-growing regions of the U.S. Recent evidence shows a great potential for anthracnose stalk rot to cause yield losses. Host genetic resistance has been successfully used to reduce loss due to Diplodia and Gibberella stalk rots of corn, but this resistance does not appear to be effective in controlling anthracnose stalk rot. Knowledge about available sources of resistance and how this resistance is inherited would aid plant breeders in breeding for resistance to anthracnose stalk rot. The objectives of these studies were to evaluate a wide array of corn germplasm for anthracnose stalk rot reaction, locate superior sources of resistance, determine how resistance is inherited in several adapted corn inbred lines, and identify the chromosome arms carrying genes for resistance in the inbred A556.
