Phomopsis seed decay in soybean isolines differing in stem termination, time of flowering, and maturity.

(...) The objective of this study was to evaluate effects of stem termination, time of flowering, maturity, and various combinations of these characteristics on seed germination and infection of seed by P. longicolla. The cultivar Clark and seven of its near-isogenic lines differing in stem termination (indeterminate vs. determinate vs. semideterminate), time of flowering (normal vs. delayed vs. late), and maturity (normal vs. late) were evaluated for seed-borne disease in Maryland and two locations in 1984 and 1985 and one location in 1986.
