Abstract

The seed- borne pathogen Pyrenophora graminea Ito& Kur. is the causal agent of barley leaf stripe, a destructive disease in most barley growing region in the world. In order to  improve the barley species in Algeria against this disease, it is necessary to know their tolerance reaction  to it. The genotype that have been tested are five parent genotypes: ACSAD,  Tichedrett,  Saida,  Rihane,  Hamra and eight populations hybrid obtained by intraspecific crosses of the parents and then sowing of F1 to F8. We compared the incidence of the isolate of Pyrenophora graminea  for morphological characters (Stem height) and yield (1000-grain weight, medium yield of plant) of the studied variety. The results obtained showed the existence of variability between our thirteen genotypes of barley which had a different resistance level in the quantitative and qualitative characters.
