Fig. 1. Distribution of 166 F2 plants from the Boggs-RR x CX1834-1-2 population on the basis of color intensity in Pi assays. Numbers on the X-axis represent relative Pi concentration based on absorbance measurements.

Fig. 2. LOD score plots for interval mapping on linkage groups (LGs) L and N in the Boggs-RR x CX1834-1-2 population. Lines parallel to the linkage groups indicate the genome-wide = 0.001 significance threshold (LOD = 3.8).

Fig. 3. Pi levels for various Satt561 (LG L) and Satt237 (LG N) marker classes in seed from a Boggs-RR x CX1834-1-2 F2 population, based on visual ratings from colorimetric assays. (Bo = allele from Boggs-RR; CX = allele from CX1834-1-2. Visual ratings: 0 = no reaction to 5.0 = dark blue. Bars represent standard errors.)

Fig. 4. Pi levels for various Satt561 (LG L) and Satt237 (LG N) marker classes in seed from a 5601T x CX1934-1-2 F5:7 population, based on absorbance. (56 = allele from 5601T; CX = allele from CX1834-1-2. Bars represent standard errors. Note that means of classes that were heterozygous at one or both loci were calculated from only 0 to 10 individuals, whereas means of classes homozygous at both loci were calculated from 30 to 51 individuals.)
