Fig. 1. Distribution of female index (FI) values for PA3 and PA14 in the F4 population developed from crossing the cultivars Bell and Colfax. Means for the parents are shown by arrows. The shaded portion illustrates the number of lines that would be selected because they are predicted to be resistant because of homozygocity for alleles from the resistant parent Bell for the simple sequence repeat markers Satt309 and Satt431.

Fig. 2. Likelihood of odds (LOD) plots showing the locations of quantitative trait loci in the F4 population developed from crossing the cultivars Bell and Colfax. The plots are based on the female index (FI) values for lines after testing with the soybean cyst nematode populations PA3 (FI 3) and PA14 (FI 14).
