RECORD AND DIAGNOSIS OF TOBACCO MOSAIC VIRUS (TMV) ON PEPPER CROP Capsicum annuum IN MOSUL FIELDS.

Abstract

The results of diagnostic study of pepper crop in Mosul fields infected with severe green mosaic symptoms and distortion, showed that the causal agent is Tobacco mosaic virus, which diagnosed using indicator plants: tomato and tobacco respond as systemic infection, showed mosaic symptoms and datura, goosefoot and wild tobacco plants, responded locally to infection as local lesions without systemic infection. Physical properties tests revealed that TIP = 90 – 95c, DEP = 10-5 – 10-6 and LIV= more than 182 days, the aging of TMV in dried leaves is more 15 months. The agglutination serological test revealed that the causal virus is TMV, by using locally prepared antiserum.
