One of the main problems for soybean in the expansion areas of Central Brazil as in the traditional crop areas of the South region, is the incidence of high insect populations, causing significant losses directly on grain yield and indirectly on grain and seed quality. Chemical control has been extensively used to avoid greater losses. The use of tolerant varieties in combination with a program of pest management is the best solution to attempt the comprehensive exigencies of economic and environmental sustainability. Our purpose was to evaluate the potential of soybean inbred lines selected in the breeding program for insect resistance developed at Embrapa Soybean. Experiments including resistant lines and commercial varieties (including the resistant standard variety IAC-100) were installed in two localities of Londrina, PR, in 2000/01 and 2001/02 crop seasons. Different pest management strategies were applied on each locality, one with standard insect control and other without control, permitting the attack of natural insect populations. The grain yielding was determined and samples of seeds derived from each plot were classified as good, medium and bad depending on the visible grain aspects. The different grain classes were weighted separately to determine their relative proportions for each genotype. Total grain yield, commercial grain yield (medium plus good grains) and good grain yield were calculated for each genotype. Resistant genotypes showed lower loss for good grain yield in relation to susceptible varieties, mainly under high insect population condition. No significant differences were observed among resistant lines and varieties for total and commercial grain yield. The inbred lines BRQ94-1311, BRQ95-2193, BRQ95-1159 and BRQ95-1873 were selected, considering their resistance level and yield potential observed along the experiments. Resistant and adapted lines can contribute with the breeding process, taking part of a new cycle of cross and selection.
