Poor quality of soybean seed has been often associated with seedborne fungi. The effects of date of planting and maturity, and harvest time on the incidence of seedborne fungi were studied in experiments conducted in 1986 and 1987. In each year, five genotypes were grown on six different planting dates at Gainesville, FL. Seeds were harvested at maturity (Ho), one week later (H1), and two weeks later (H2). The blotter test was used to assess fungal infection and seed germination. Results from the two years were different primarily due to more moisture during the period of seed maturation in 1986 and a relatively dry season 1987. Extensive fungal infection was achieved only under high moisture conditions. Phomopsis spp., Fusarium spp., and Colletotrichum truncatum, in that order, were the most important fungi that infected seeds. the incidence of other fungal species that caused seed deterioration was insignificant. Extensive infection of seed by C. truncatum occurred only in early-maturing seeds subjected to high temperatures and heavy rainfall. Extensive infection of seeds by Phomopsis sp. and Fusarium sp. occurred when seeds matured under conditions of high humidity. Early planted and early maturing genotypes had the highest percentage of seed with fungal infection and the lowest percentage of seed germination. Fungal infection of seed increased substantially with delay in harvest and seed germination declined proportionally to the infection level. The inheritance of resistance of seed to Phomopsis ...
