ED - International Crop Science Congress TI - Strategy for the identification and breeding of resistance to dryland root rot complex for international spring and winter wheat breeding programs SN - 1 920842 21 7 PY - 2004/// CY - Gosford (Australia) PB - The Regional Institute KW - Wheat KW - AGROVOC KW - Root rots KW - Disease resistance KW - Drylands KW - Plant breeding KW - Tolerance N1 - Draft N2 - Root, crown and foot root rots, including the complex of Crown Rot Fusarium (F. psuedogramiearum, F. culmorum) and Common Root Rot (Bipolaris sorokinana) are causing economic yield loss in many parts of the world where cereals predominate the cropping system and sub-optimal growing conditions and rainfed or limited irrigation practices are common. CIMMYT in collaboration with the Turkish Ministry of Agriculture and Rural Affairs have established an International field and laboratory screening program for identifying spring and winter wheat accessions with resistance to these root pathogens. Assessment of tolerance with the most promising lines is also occurring to identify accessions with combined resistance and tolerance. The strategy in place is described with reference to subsequent breeding and seed dissemination in addition to some of the most promising lines identified.
