Phoma lingam-a rapeseed parasite in Serbia

摘要

The rapeseed (Brassica napus L.) was grown in Serbia already in 1930s. However, organized production and a stedy increase in the acreage under winter rapeseed have been registered in recent years. The main reason for the increase in rapeseed acreage is that rapeseed can be used for production of biodiesel. Although the current acreage is relatively small, disease symptoms caused by certain phytopathogenic fungi have already been observed in rapeseed fields. This paper describes the symptoms caused by the pathogenic fungus Phoma lingam. In addition to the description of symptoms, the paper contains descriptions of morphological characteristics of the fungus cultured on PDA and oat agar, results of pycnospore and pycnidium counts and the results of field trials for rapeseed resistance to the disease.
