Impact of pathogen genetics on breeding for resistance to sugarcane diseases* [Full subscriber]

Abstract Diseases are limiting factors of sugarcane production and breeding for resistance to diseases is a major goal in sugarcane variety improvement. Diseases result from complex interactions between plants, pathogens and environment, including humans and insect vectors of pathogens. History has shown that durability of resistance of sugarcane to diseases varies according to the host cultivar and to the pathogen in a given environment. Some sugarcane cultivars have been grown for decades without losing efficiency of resistance to the disease they were bred or screened for; others became susceptible and showed disease symptoms rapidly after being grown commercially. Disease outbreaks…
