1. Preheat oven to 350°. Bake pecans in a single layer in a shallow pan 8 to 10 minutes or until toasted and fragrant, stirring halfway through. Cool 15 minutes.
Stir together flour and next 6 ingredients in a large bowl; add peaches, next 4 ingredients, and toasted pecans, stirring just until dry ingredients are moistened. Spoon batter into a lightly greased 9- x 5-inch loaf pan.
3. Bake at 350° for 1 hour and 5 minutes to 1 hour and 10 minutes or until a long wooden pick inserted in center comes out clean. Cool in pan on a wire rack 5 minutes. Remove from pan to wire rack, and cool completely (about 1 hour).
