Abstract excerpt
The seed of all wild Glycine accessions have black or brown pigments because of the homozygous recessive i allele in combination with alleles at the R and T loci. In contrast, nearly all commercial soybean (Glycine max) varieties are yellow due to the presence of a dominant allele of the I locus (either I or i) that inhibits pigmentation in the seed coats. Spontaneous mutations to the recessive i allele occur in...
