Genetic Linkage in Soybeans. Linkage Group IV1

  1. Martin G. Weiss2

Abstract

Abstract

The genetic linkage between three loci in soybeans was determined and established as Linkage Group IV. The loci involved were V1, v1 (normal chlorophyll variegated leaves); Na, na (ovate, lanceolate leaflets); and P2,p2 (normal, minute pubescence or “puberulence”). The order of genes was shown to be v1-na-p2. The combined recombination value for v1 and na was 35.6 ± 0.9%, for na and p2 was 26.4 ± 1.4%, and random assortment of v1 and p2 occurred. Greater frequency of 4.seeded pods was shown to be a pleiotropic effect of the gene that causes narrow leaflets.
