Abstract
Two soybean (Glycine mar) lines differing in resistance to Phomopsis s eed decay were evaluated in field trials, over 3 yr, for time and inci dence of pod and seed infection caused by Phomopsis longicolla, Diapor the phaseolorum var. caulivora and D. p. var. sojae. Pod infection inc reased linearly with time but OX615 averaged 15% less than Coles at ea ch sample date. Seed infection increased curvilinearly in conjunction with decreasing seed moisture with marked increases between the fifth and seventh weeks after flowering. At maturity, average seed infection was 69% in Coles and 28% in OX615.
