Host–pathogen interactions of Brassica genotypes for white rust (Albugo candida) disease severity under aided epiphytotic conditions in India
Phytoparasitica 43 (2), 197-207
Abstract: A total of 13 strains of oilseed Brassica genotypes were evaluated for their reaction to white rust pathogen Albugo candida Pers. Kuntze during crop seasons 2007–08, 2008–09 and 2009–10 at five agroclimatically diverse locations in India. Aided epiphytotic conditions were provided to ensure heavy disease pressure at all the locations. The disease reaction of different genotypes was recorded at 100 days after sowing (DAS) as per cent disease severity based on per cent leaf area affected by the pathogen. Genotypes exhibited variable disease reaction in space and time indicating the prevalence of different isolate(s) of the pathogen. However, some genotypes like PBC 9221, EC 414299 and GSL-1 exhibited resistant reaction to white rust pathogen across the locations consistently during the three cropping seasons. Some of the genotypes showed specific resistant disease reaction at a specific location indicating their suitability for cultivation at that particular location. For example, JMM 07-1, JMM 07-2 and JYM 10 have shown specific resistance reaction to isolate(s) of white rust at Morena location. It can be concluded from the study that some of the genotypes showed resistant reaction to prevalent isolates of an area. Thus, it is advised to test the genotypes for the reaction to a particular/range of diseases for the specificity in performance, if any, before release for general cultivation in a particular area.
