The aim of wide crossing is to transfer useful genes from the wild relatives of crops into cultivars. The wild relative of modern cultivars possess many desirable traits such as resistance to diseases and insects, tolerance to abiotic stresses, high seed protein content, and sources of male sterility. This paper describes achievements in using genes from wild relatives of rice, barley, wheat, and cotton. It shows the success in hybrid rice production in China and how basic sources of male sterility are derived from wild rice. The techniques available for sexual and parasexual gene transfer are also analyzed.
