Late blight resistance in a diploid full-sib potato family
Late blight, caused by Phytophthora infestans (Mont.) de Bary, is the most destructive disease of potato worldwide. As this pathogen can rapidly overcome major race-specific resistance genes, identifying the basis for enhanced quantitative resistance has become a crucial element for implementing advanced breeding strategies. A population of 230 full-sib progeny derived from a cross between two ...
متن کاملLate Blight Resistance of RB Transgenic Potato Lines
Late blight of potato (Solanum tuberosum L.), incited by Phytophthora infestans (Mont.) de Bary, is a devastating disease affecting tuber yield and storage. Recent work has isolated a resistance gene, RB, from the wild species Solanum bulbocastanum Dun. Earlier work in Toluca, Mexico, observed significant levels of field resistance under intense disease pressure in a somatic hybrid containing R...
متن کاملEffect of Host Plant Resistance and Reduced Rates and Frequencies of Fungicide Application to Control Potato Late Blight
Late blight of potato (Solanum tuberosum, L.) caused by Phytophthora infestans (Mont.) de Bary, is a major worldwide threat to the production of high quality potatoes (12). Unchecked, P. infestans can rapidly defoliate plants in the field and can infect potato tubers when spores are washed into the soil (15). Prior to the early 1990s, the population of P. infestans throughout much of the world ...
متن کاملEvaluation of potato late blight management utilizing host plant resistance and reduced rates and frequencies of fungicide applications
Field experiments were carried out (2001–2003) to evaluate the efficacy of combining host resistance with reduced rates and frequencies of the residual contact fungicide fluazinam to control foliar potato late blight (Phytophthora infestans). Potato cultivars (cvs.) and advanced breeding lines (ABL) developed in four states were used in combination with fluazinam applications at 0, 33%, 50%, 66...
