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.)
