Abstract
Plant virology was founded in the former Institute of Phytopathology Aschersleben by Maximilian Klinkowski. Research in the field of plant virology was undertaken there in three areas. The research started with the analysis of virus diseases in cultivated plants in the GDR; the second main area was the virus diagnosis: the third - virus resistance. An important prerequisite, which was very important for an effective research in this field, was the close cooperation within the institute as well as with other institutions of scientific research and practice within our country and abraoad. From 1970 to 1990, 36 host-virus-combinations were investigated with regard to virus resistance by the department 'Research on Virus Diseases' at the institute. A research task was considered being resolved when the results were confirmed in the breeding practice. Reliable methods and procedures of testing for virus resistance represent an important basis for the investigation of virus resistance. Such methods were developed for each of the investigated host-virus-combinations and summarized in a catalugue. Methods of evaluation of virus resistance were included in the procedures. Research of virus resistance and testing for virus resistance were carried out in parallel and closely connected. One of the first results of the investigations was the characterization of types of resistance. Two basic types were, in fact, classified, "qualitative or localizing virus resistance" and "quantitative or non-localizing virus resistance". In this connection the most important characteristics of resistance and influencing factors as well as their interactions were investgated. Practical result was the transfer of 37 genotypes of various virus-resistant cultivars giving high yields. Some of the genotypes showed multiple or complex resistance. Furthermore, extensive breeding material was selected which was destined for further use in breeding. When the Institute of Phytopathology Aschersleben was closed in 1991, the department 'Research of Virus Diseases' also had to finsh its work.
