1 College of Agriculture and Life Sciences Department of Plant Breeding Developing Breeding Lines with Anthracnose Stalk Rot Resistance from Exotic Maize Germplasm Margaret Smith

2 College of Agriculture and Life Sciences Department of Plant Breeding Anthracnose Stalk Rot Colletotrichum graminicola (Ces.) G.W. Wils. Increased lodging, reduced yield Best control through resistant varieties

3 College of Agriculture and Life Sciences Department of Plant Breeding Overall Project Objective Develop temperate-adapted maize inbreds with both anthracnose stalk rot resistance and good yield potential from GEM breeding populations

4 College of Agriculture and Life Sciences Department of Plant Breeding Selection and Breeding Scheme

5 College of Agriculture and Life Sciences Department of Plant Breeding Selected Populations 1)FS8B(T):N1802 2)CH04030:S0906 3)AR01150:N0406 4) GOQUEEN:N1603

6 College of Agriculture and Life Sciences Department of Plant Breeding Means by source population for anthracnose stalk rot ratings, 2001

7 College of Agriculture and Life Sciences Department of Plant Breeding Yield Data - 2 locations, 2001

8 College of Agriculture and Life Sciences Department of Plant Breeding Yield Data - 1 location, 2001

9 College of Agriculture and Life Sciences Department of Plant Breeding 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 –Holden’s testers (LH176/LH177, LH198)
