Back in 2011 we reported on a new type of broccoli containing 2-3 times the amount of the phytonutrient glucoraphanin compared to other varieties.
The “suped up” cultivar was produced by crossing broccoli with a wild relative from Sicily that produced high levels of glucoraphanin. Over multiple generations plants would have been selected that produced a high quality broccoli with the desired increased glucoraphanin levels.
After 3 years of field trails in the US and Europe the plants have been shown to consistently produce the higher levels of glucoraphanin.
