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

open access: yes, 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.

Spot form of net blotch resistance in barley is under complex genetic control [PDF]

open access: yesTheoretical and Applied Genetics, 2015
Evaluation of resistance to Pyrenophora teres f. maculata in barley breeding populations via association mapping revealed a complex genetic architecture comprising a mixture of major and minor effect genes. In the search for stable resistance to spot form of net blotch (Pyrenophora teres f.
