Hedges, R. Palmer] Three chlorophyll-deficient mutants (CD-1, CD-2, and CD-3), derived from the progeny of independent germinal revertants from thew4-mutable soybean line [Glycine max (L.) Merrill], were characterized genetically. Electrophoretic analyses indicated that these lines lacked two of three mitochondrial malate dehydrogenase isozymes (MDH−). The absence of two MDH bands was conditioned by a recessive allele at a locus designatedMdh1. All three CDs were allelic to each other and to T253, a Harosoy isoliney20-k2 MDH− from the Genetic Type Collection. The MDH− phenotype and the yellow-green plant phenotype were each inherited as single recessive alleles. No recombination between the two traits was found in nine F2 populations from crosses of the CDs by wild-type soybean lines. Complete linkage of theMdh1 andy20 loci suggested that the mutations in the chlorophyll-deficient lines were deletions. Phenotypic differences among the CDs suggested that the deletions may have different endpoints. The chromosomal aberrations were not large enough to affect transmission ofy20 andMdh1 mutant alleles through the pollen or ovule. CD-1, CD-2, and CD-3 were added to the Soybean Genetic Type Collection as T323, T324, and T325, respectively.
