Septoria tritici blotch is currently the major foliar disease of wheat in most of Europe, North Africa, South America, and several other parts of the world. Until recently, little was known about the genetics of resistance to this disease in comparison to, for example, the better-studied rust diseases and mildew. New sources of resistance and improved knowledge about the genetics of resistance ...

background and objectives: septoria tritici blotch (stb), caused by mycosphaerella graminicola (anamorph s. tritici) is currently the most serious disease of wheat worldwide. this study was established to determine the function of resistant genes of m. graminicola to find out the number of genes corresponding in resistant reaction and also to estimate the genetic parameters of resistance. mater...

to study inheritance of resistance to septoria tritici blotch in wheat, the generation mean analysis method was used. so six generations (p1, p2, f1, f2, bc1 and bc2) were planted under completely randomized design with three replications in greenhouse. seedlings were inoculated at the second-leaf stage with an isolate of septoria tritici and necrosis and picnidia density and area under disease...

Septoria tritici blotch (STB), caused by the ascomycete fungus Mycosphaerella graminicola (asexual stage: Septoria tritici), is one of the most important foliar diseases of wheat. In this research, quantitative expression analysis of five candidate genes for the induction of resistance to STB (PR-1, Bsi, Msr, Per, and Ppi) was conducted in the wheat cultivars ‘Seri 82’ (susceptible) and ‘Fronta...

septoria tritici blotch (stb), caused by mycosphaerella graminicola (anamorph: septoria tritici), is one of the most important diseases of wheat worldwide that has been intensified recently in some regions of iran including moghan plain. in this study reaction of 23 bread and durum wheat cultivars to 10 isolates of the pathogen collected from moghan region during 2007 and 2008, were evaluated u...

Northern areas of the western United States are one of the most productive wheat growing regions in the United States. Increasing productivity through breeding is hindered by several biotic stresses which slow and constrain targeted yield improvement. In order to understand genetic variation for stripe rust (Puccinia striiformis f. sp. tritici), Septoria tritici blotch (Mycosphaerella graminico...

septoria tritici blotch is an important wheat disease in many areas of the world including iran's warm, humidregions. in this study, crosses were made between resistant breeding line bobwhite#1/fengkang andcommercial cultivars moghan3, koohdasht, tajan and morvarid, and derived f1, f2, bc1 and bc2 generations were used to determine the genetic control of necrosis, pycnidia traits and the area u...
