Virulence of Moroccan f. Revealed by International Differential Barley Genotypes [PDF]

, 2016
Pyrenophora teres f. teres (Ptt), causing net blotch in barley, is an important and frequently isolated leaf pathogen across the globe. The virulence spectrum of Ptt from North Africa including Morocco is poorly understood.

Quantification of leaf stripe, Pyrenophora graminea, in barley seed by real-time PCR [PDF]

, 2005
In some years, large amounts of organic seed lots are discarded due to the presence of high levels of seed-borne diseases. In barley it is especially the presence of the fungal species Pyrenophora teres (barley net blotch) and P.

Genome-wide association mapping of net form net blotch resistance in barley at seedling and adult plant stages

Frontiers in Agronomy
Net form net blotch (NFNB) caused by Pyrenophora teres f. sp. teres (Ptt) is an emerging barley disease in several countries. It causes severe yield and quality losses due to infection of leaves, kernels, and stems.
