- ... Irrigation wheat production in South Africa is seriously impaired by the regular occurrence of Fusarium head blight epidemics. The disease was noted for the first time in 1980 and has since caused damage whenever the seasonal climatic conditions were favourable. Higher levels of disease concurred with an increase in conservation tillage and maize production in a double cropping system with wheat. ...

- ... Stripe rust, caused by Puccinia striiformis f. sp. tritici, is a serious disease of wheat. The spring wheat cultivar Kariega expresses complete adult plant resistance to stripe rust, whereas Avocet S is susceptible. In former studies, quantitative trait loci (QTL) analysis of doubled haploid lines derived from a Kariega x Avocet S cross revealed two major QTL (QYr.sgi-7D and QYr.sgi-2B.1) and two ...
