From landrace to modern hybrid broccoli: the genomic and morphological domestication syndrome within a diverse B. oleracea collection.

Cross-Sectional Study

The study found that old Italian broccoli varieties are genetically very different from modern broccoli and cauliflower types, and they didn’t mix much with them over time, meaning they evolved on their own.

Similar Assertions

The broccoli we buy in stores today has much less genetic variety than the old-fashioned types grown in southern Italy, meaning farmers have lost a lot of natural diversity by breeding for uniformity.
