Summary

One hundred samples of tomato seeds were collected

in 2011 and 2012 from tomato-cultivated fields in

Saudi Arabia and screened for their seed-borne

mycoflora. A total of 30 genera and 57 species of fungi

were recovered from the collected seed samples

using agar plate and deep-freezing blotter methods.

The two methods differed as regards the frequency

of recovered seed-borne fungi. Seven fungi among

those recovered from tomato seeds, which are known

as plant pathogens, were tested for their pathogenicity

and transmission on tomato seedlings. The recovery

rate of these pathogens gradually decreased from

root up to the upper stem, and did not reach to the

stem apex. The distribution of tomato seed-borne
