Genetic Linkage in Soybeans: Linkage Group VII¹

Abstract

The genetic linkage between three loci in soybeans was determined, and established as Linkage Group VII. The loci involved arc Y 13 , y 13 (normal, deficient chlorophyll); 0, o (brown, red‐brown seed coat pigmentation); and I, i l , i k , i (multiple alleles determining the seed coat pattern of black and brown colors). The combined recombination value between the y 13 and o loci was 31.3 ± 1.9%, between the o and i loci 17.8 ± 0.79%, and between the y 13 and i loci 41.1 ± 0.9%. The order of genes was shown to be y 13 ‐ o ‐ i.
