Climate change calls for novel approaches to include environmental effects in future breeding programs forage crops. A set of ryegrasses (Lolium) varieties was evaluated multiple European environments crown rust (Puccinia coronata f. sp. lolii) and stem (P. graminis graminicola) resistance. Additive Main Effect Multiplicative Interaction (AMMI) analysis revealed significant genotype (G) environ...

Recently a Meloidogyne species complex was detected parasitizing and causing damage to irrigated rice in southern Brazil, highlighting the need study genetic diversity of these their pathogenicity Oryza spp. order select genotypes with multiple resistance. This compared Brazilian isolates from evaluated reaction four wild accessions (O. glumaepatula, O. longistaminata, grandiglumis, alta) two c...

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...

Switchgrass (Panicum virgatum) is a perennial C 4 grass native to the central prairies of North America. Recent development of switchgrass as a sustainable biofuel feedstock has raised interest in diseases that could impact switchgrass, especially when grown under monoculture conditions. Among the known diseases of switchgrass, rust diseases are the most widespread and could potentially impact ...
