Plant genome sizes

The enormous genome of wheat, the apparent lack of link between genetic
mass and performance is - to me, at any rate - something of a mystery.
Does anyone have an idea - other than chance, 'ploidy and parasitic DNA -
why this occurs? The jack bean has (I think) hundreds of copies of the urease
gene because it has accidentally happened upon this as a storage protein;
but as to the rest...? Does wheat really have so complex a repertoire of
responses compared to, say, barley?
