Fifteen soybean cultivars of Maturity Groups VIII and IX were evaluated for seed quality during two growing seasons (1986/87 and 1987/88) at six locations in northwestern Argentina. Mature pod and seed samples were assayed by plating them on potato-dextrose agar after surface disinfestation. Occurrence of pod and seedborne fungi and seed germination were recorded after incubation at 24-26C for 7 days. The prevalent pathogens isolated from pods and seeds were species associated with the Diaporthe/Phomopsis disease complex (D/P), Cercospora kikuchii (CK), Alternaria spp. (ALT), Fusarium spp. (Fus), and Colletotrichum spp. (Coll). In 1987/88, when more rain fell, incidence of D/P pod and seed infection was higher (17.9 and 24.8%, respectivelly) than in 1986/87 (8.3 and 4.2%), a drier season. Infection by CK averaged 39.4% in pods and 9.4% in seeds in 1986/87 and 35.7% and 7.8% in 1987/88. Recovery of Fus and Coll increased and Alt decreased the second year. Although both groups had similar levels of pod inoculum, group VIII cultivars had significantly higher percent seed infection than did group IX cultivars. Differences were also detected within each group. The cultivars with best seed quality and highest percent germination in groups VIII and IX were Mineira and UFV-5, respectively. Differences in seed infection among growing areas were related to environmental differences. Seeds with lowest levels of seed infection were produced at Ceibalito (Salta) and Monte Redondo (Tucuman), wich had lower rainfall during .....
