WebA big factor here is that many plants can have more copies of their DNA than vertebrates can. Vertebrates are typically diploid (two DNA copies), but plants are often polyploid (more than two copies of DNA).

Evolutionary plant breeding describes practices which use mass populations with diverse genotypes grown under competitive natural selection.
