H. aEffect of genotype and harvest date on the incidence of seed-borne fungi and field emergence of soybean. c1979 ap.179-189. aTwenty-four cultivars of soybean (Glycine max) were selected on the basis of their performance in a preliminary screeding and grown in a replicated trial at Isabela, Puerto Rico in February 1976. Plots were harvested at maturity and 2 and 4 weeks after maturity (delayed harvests). Seeds of each cultivar and harvest date were assayed for the presence of internally seed-borne fungi and tested for emergence in sand in the field. As harvest date was delayed, the incidence of seed-borne fungi increased and seed viability decreased. Significant differences were found among cultivars for percentage total internally seed-borne fungi, Phomopsis spp., emergence in sand and emergence in the field. Significant cultivar x harvest date interactions indicate differences among cultivars in rate of seed viability under tropical conditions. aColheita aFungo aSemente aSoja aFungus aHarvest aSeed aSoybean1 aELLIS, M.
