Abstract
Bean plants have been reported to be the host plants for a number of viruses.
Among them the most common are bean common mosaic virus, bean yellow mosaic virus and cucumber mosaic virus.
Bean common mosaic virus and cucumber mosaic virus are known to be transmitted by seeds of some plants.
The objective of the study was to analyze the role of bean seed in transmitting the above mentioned viruses.
The following two bean cultivars were involved in the study: cv.
Improved Gradištanac and its lines and cv.
Tetovac.
Plants which have previously been tested and confirmed as virus diseased were grown under field conditions.
Seeds were harvested and sown in pots with sterile soil.
Emergence, growth and the incidence of virus symptoms were assessed under greenhouse conditions.
The incidence of virus diseases on seedlings were tested with the help of mechanical transmission to corresponding indicator plants.
A total of 8000 seeds were tested.
The incidence of virus diseases was confirmed on a considerable number of seedlings.
A far greater percentage of bean lines cv.
Improved Gradištanac were virus diseased compared with cv.
Tetovac.
Transmission ranged from 20% (cucumber mosaic virus) to 26% (bean common mosaic virus). Based on the results obtained it can be concluded that virus diseased bean seeds play a major role in further disease spread.
