Inheritance of an Albino Seedling Character in Arachis hypogaea L.1

Terry A. Coffelt2 and Ray O. Hammons3

Twenty F2 progenies of reciprocal crosses between Arachis hypogaea L. cultivars ‘Argentine’ and ‘Early Runner’ were grown in greenhouse or field plantings. At 2 to 4 weeks of age 11,973 seedlings were classified for albino vs. normal green plant color. All chlorophyll-deficient lethal seedlings were scored as albino. The results indicate that the two cultivars differ at three loci conditioning albinism. No differences occurred for the reciprocal cross. Results indicate that chlorophyll production is controlled by duplicate loci interacting in an epistatic manner with another locus. Gene symbols C1 and C2 are proposed for the duplicate alleles; L designates the third locus. Chi-squares give good fits to a phenotypic ratio of 60 green:3 albino:1 zygotic lethal. A reexamination of results from earlier studies shows that those data are not incompatible with this new genetic model.

Key Words: Chlorophyll-deficient • Duplicate loci • Epistasis • Infraspecific hybridization • Peanuts • Zygotic lethal
