Eleven naturally infected and four uninfected sunflower seed samples collected from different production areas of pakistan were tested for seed germination. Germination in all the infected sunflower seed samples was significantly lower as compared with healthy samples. The seed samples hav ing high infection of Alternaria alternata (Fr.) Kessler alone reduced the germination to the same extent when its infection was low but in combination of other pathogens especially with Fusarium spp. and Macrophomina phaseolina (Tassi) Goid. The number of abnormal seedlings and the recovery percentage of various seed borne fungi from the abnormal seedlings during germination was dependent on their infection level in the seed.
