Technical Abstract: Bean pod mottle virus (BPMV) is a member of the genus Comovirus, identified in 1999 for the first time in Ohio. BPMV infection is associated with seed mottling, which dramatically reduces the value of food grade soybeans, and yield loss, especially in plants coinfected with Soybean mosaic virus. Put the reason for doing the experiment up front here: To determine whether insect resistance in soybeans influenced the movement of BPMV in the field, five soybean lines, two with resistance to coleopteran insect feeding and three lacking resistance were evaluated in a split plot model field need to list the main and split effects here at early and late stages. An Ohio isolate of BPMV purified from soybean leaves was used to inoculate unifoliate leaves of two or 20 plants per plot. Leaves from individual plants were sampled at early (R2) and late (R7) stages to test for BPMV within the plots. Preliminary results from the early sampling indicated that APMV incidence was lower in HC94-24, an insect resistant line, than in plots with varieties without insect resistance. HC94-24 had 16.45 and 20.45% BPMV incidence in the plots for the two inoculation treatments, while Resnik, a susceptible line, had 25 and 37.6% incidence for the same treatments.
