AB - Abstract A set of BC1F2 populations derived from common bean × tepary bean interspecific hybrids was examined for isozyme segregation within 12 different enzyme systems. The BC1F1 parents of the BC1F2 populations, as inferred from the BC1F2 progeny data, were found to be heterozygous for approximately half of the marker loci examined, in agreement with transmission genetic theory predictions. In contrast, segregation ratios for isozyme loci in the BC1F2 families deviated significantly from expected Mendelian ratios in approximately 50% of the cases, due to a severe deficiency of individuals homozygous for the tepary allele, as well as having a deficiency of heterozygotes in some cases. Using data from a diagnostic pair of linked isozyme loci, evidence of intergenomic recombination at levels equal to or greater than that encountered in intraspecific crosses was detected in one BC1F2 family.
