Black point incidence in some winter wheat varieties cultivated in North-Eastern Romania

Abstract

Black point is a common disease in all wheat growing regions of the world and is an important quality defect of the wheat kernel. Black point can be characterized by a dark brown to black discoloration of the pericarp and testa, primarily embryo sides of the grains. Wheat kernel black point disease is associated with many microorganisms, both fungi or bacteria, but those most usually responsable for these symptoms are species of the fungus Alternaria alternata, Cochliobolus sativus, Fusarium graminearum, Aspergillus spp., Penicillium spp.. This study was undertaken to investigate the incidence of black point on some winter wheat cultivars in the nord-est area of Romania. Twenty-eight (Triticum aestivum L.) winter wheat varieties were compared for reaction to black point in a 2-years field trials. There were individual varietal differences in black point incidence within each of the varieties.
