Glucose and starch, which breaks down to glucose, are preferable to fructose and anything containing fructose, such as sucrose and HFCS, because of the metabolic damage wrought by fructose.
Root vegetables are mostly starch. Winter squash and other vegetables which are actually fruits contain varying amounts of starch, glucose, sucrose and fructose. Winter squashes (we call them all pumpkins) get a rough time on this site but they are only about 20% carb, most of which is starch. Unless you're doing VLC there should be plenty of room in your diet for pumpkin. There is in mine.
If you want fructose (why?), go for the traditional fruits. Anything sweet enough to be commonly called a fruit has plenty of fructose. The fruits that aren't that sweet are usually called vegetables and have little fructose
