Your tomato blossoms probably didn't set fruit, because last summer's heat killed the pollen. When nights are above 70F and days are over 90F, pollen becomes sterile. If you only planted Silver Queen corn and no other variety, the odds are your saved seed will grow true. If there were other corn varieties in the area, they probably crossed with Silver Queen. You might come up with something interesting, though!
