Presentation Transcript

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

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

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

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

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

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

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

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

  9. 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) College of Agriculture and Life Sciences Department of Plant Breeding
