Often cross pollinated crops are

Often cross-pollinated crops are Cotton, Tobacco and Sorghum.
In some crop plants, cross-pollination often exceeds 5 percent and may reach 30 percent. Such species are generally known as often cross-pollinated species.
Cultivated sorghum is primarily self-pollinating; however, wind-mediated cross-pollination does occur.
Cotton is an often cross-pollinated crop. The percentage of cross-pollination varies from 5 - 25% promoted by insects. The slightly elevated position of the stigmatic surface leads to occasional cross-pollination.
Tobacco is normally self-pollinated, although as much as 4 to 10 percent of cross-pollination occurs from pollen carried by insects.
