Evaluation of sugarcane introgression lines for resistance to brown rust disease caused by Puccinia melanocephala [PDF]

Tropical Plant Pathology, 2013
Sugarcane brown rust disease caused by Puccinia melanocephala is one of the important fungal diseases affecting sugarcane yield around the world. Cultivar resistance is the most appropriate control method for this disease. In this study, 62 introgression

Putative resistance-associated genes induced in sugarcane in response to the brown rust fungus, Puccinia melanocephala and their use in genetic diversity analysis of Louisiana sugarcane clones

Plant Gene, 2018
Development of resistant cultivars is the main control measure against sugarcane brown rust caused by Puccinia melanocephala. Durability is uncertain, since the pathogen possesses adaptive ability to overcome host plant resistance.

Variability in Puccinia melanocephala Pathogenicity and Resistance in Sugarcane Cultivars. [PDF]

Plant Disease, 2014
Brown rust, caused by Puccinia melanocephala, is an important disease of sugarcane worldwide, controlled primarily with host plant resistance. Disease response shifts from resistant to susceptible have been repeatedly observed for cultivars. However, information is limited concerning pathogen variability related to host reactions.

Genetic diversity among Puccinia melanocephala isolates from Brazil assessed using simple sequence repeat markers.

Genetics and Molecular Research, 2014
Brown rust (causal agent Puccinia melanocephala) is an important sugarcane disease that is responsible for large losses in yield worldwide. Despite its importance, little is known regarding the genetic diversity of this pathogen in the main Brazilian sugarcane cultivation areas.

Resistance of Sugarcane Cultivar R 570 to Puccinia melanocephala Isolatesfrom Different Geographic Locations. [PDF]

Plant Disease, 2001
Two different inoculation techniques were investigated before studying the reaction of the major rust resistance gene of sugarcane cultivar R 570 against isolates of Puccinia melanocephala from different geographic locations. Cultivar R 570 exhibited severe rust symptoms when in vitro plantlets were inoculated with a rust isolate from Réunion Island ...
