Description
Summary:Lentil [Lens culinaris ssp. culinaris (Medik.) Williams] is a major grain legume (pulse) crop in North America. Various markets demand specific seed coat colors and/or patterns. We attempted to determine the mode of inheritance of seed coat color and pattern in the lentil. Inheritance studies involving crosses between parental lines with various seed coat colors and patterns indicated that seed coat color is determined by two independent loci. The dominant allele at one locus (Ggc) determines gray seed coat color, and the dominant allele at the second locus (Tgc) determines tan seed coat color. The two dominant alleles (Ggc Tgc) interact to produce a brown seed coat, whereas the double recessive (ggc tgc) is green. Seed coat pattern is determined by a series of five alleles at another locus. Marbled-1 (Scp(m1)) is dominant to marbled-2 (Scp(m2)), spotted (Scp(s)), dotted (Scp(d)), and absent (scp). Scp(m2) is dominant to Scp(s), Scp(d), and scp. Scp(s) and Scp(d) are codominant alleles, both of which are dominant to scp
