Developing Breeding Lines with Anthracnose Stalk
Rot Resistancefrom Exotic Maize Germplasm

• Margaret Smith

2
Anthracnose Stalk Rot

• Colletotrichum graminicola (Ces.) G.W. Wils.
• Increased lodging, reduced yield
• Best control through resistant varieties

3
Overall Project Objective

• Develop temperate-adapted maize inbreds
• with both anthracnose stalk rot resistance and
• good yield potential
• from GEM breeding populations

Work done in 2002

• S6 progenies planted ear-to-row
• Greater emphasis on yield performance
• Greater tolerance of stalk rot resistance
• Testcrosses made to
• Previously used public line crosses
• Holdens testers (LH176/LH177, LH198)
