Tolerance of some barley varities to leaf rust disease in Egyptl [electronic resource].

Includes references.

Five Egyptian barley varieties i.e. Giza 123, Giza 124, Giza 125, Giza 126, and Giza 2000 were evaluated for their levels of tolerance to leaf rust disease under field conditions at Sakha Agricultural Research Station during 2007/08 and 2008/09 successive seasons. Tolerance was relatively determined in barley varieties against leaf rust by estimating the correlation between disease variables i.e. final rust severity (%), area under disease progress curve and four yield components (weight of grain/spike, 1000 grain weight, biological yield and yield/plot). Different levels of infection were obtained by foliar spray with the systemic fungicide (Saprol).
