Heat oven to 375°F. In 1-quart saucepan, cook basting sauce ingredients over low heat 3 to 4 minutes, stirring occasionally, until marmalade is melted.
In 15x10x1-inch pan, place chicken breasts. Brush with half of the basting sauce. In medium bowl, toss potatoes and onion with oil; place around chicken. Bake 25 minutes.
Meanwhile, in small bowl, soak cranberries in 1/4 cup orange juice.
Brush chicken again with remaining basting sauce. Stir gently to coat vegetables with pan juices. With slotted spoon, sprinkle cranberries over vegetables; drizzle with juice. Bake about 20 minutes longer or until juice of chicken is clear when thickest part is cut to bone (170°F), and vegetables are tender.
