  1. Inheritance of resistance to gray leaf spot of corn

    Coates, Stephen ThompsonUniversity of Illinois at Urbana-Champaign2011

    Twenty-four corn inbreds, selected for resistance to gray leaf spot (caused by Cercospora zeae-maydis) in 1989 and 1990, were crossed with the susceptible inbreds FR1141 and/or FR20 and populations of four to six generations were produced. In 1991, the populations were evaluated for gray leaf spot …

  8. Sources and Inheritance of Resistance to Anthracnose Stalk Rot of Corn

    Carson, Martin LeroyUniversity of Illinois at Urbana-Champaign2014

    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 …
