Yellowing of wheat leaves

Wheat    None Given

A Major portion of wheat leaves is yellow with brown spots in random. Leaves enclosed with brown spot area become dead. Can someone help me in identifying the disease. Is it spot blotch or leaf blight of wheat?

I guess I have seen this befor at corn plants. It is a fungus diesease and called "Kabatiella zeae". In your case either the diesease is advanced or combined with other diseases. I could imagine the second disease is lesion mimic, caused by environmental conditions.

At least 3 of 5 leaves on the picture have symptoms of virus disease - wheat spindle streak virus and /or cereal yellow dwarf virus. The leaf in the middle has fungal disease-like symptoms, but it is not clear enough to say more.
