520			_aWheat production in South Africa commenced in 1652. Wheat breeding was initiated at the beginning of this century. Stem rust susceptibility of old and new cultivars was the first challenge confronting wheat breeders. As early as 1912, the first interspecies crosses were attempted in order to improve disease resistance of cultivars. In the mid-thirties, bread wheat quality first became important. In 1978, the appearance of the Russian wheat aphid became a new challenge to South African wheat breeders. This paper describes the winter and spring agrotypes required as well as the advances wheat breeders have made during the past century .
