Abstract

The studies carried out in 1997-1998 were aimed at evaluating the incidence of Broad bean stain virus (BBSV) in pea seed material, susceptibility of pea cultivars to the virus and transmission of BBSV by seeds of selected pea cultivars. Experiments were performed in field conditions and in a greenhouse. The presence of the virus in pea plants and seeds was determined by isolation onto Chenopodium murale or serologically by ELISA test. In the seed material, the virus was detected only in 0.1% of the seeds. The pea cultivars: Cud Kelvedonu, Delisa II, Hejga, Iłówiecki, Konserwowy IHAR, Maraton, Nefryt, Pegaz, Sześciotygodniowy and Telefon, appeared to be susceptible to the infection by BBSV and percentage of infected plants ranged from 6.6 to 35%. Transmission of the virus by seeds occurred in all cultivars mentioned above except for cv. Maraton and percentage of infected seeds ranged from 2.9 to 50.0, depending on cultivar of pea.
