Inheritance of alleles for Cgy1 and Gy 4 storage protein genes in soybean.

A cultivar lacking the glycinin subunit A5A4B3 ('Raiden') was crossed with one lacking the α'-subunit of β-conglycinin ('Keburi'). Analysis of F2 and F3 progeny indicated that the missing bands of the A5A4B3 and the α'-subunit were each controlled by a recessive allele of two independently segregating genes. Gene symbols Gy 4/gy 4 and Cgy 1/cgy 1 were proposed for the genes which confer the presence or absence of the glycinin and conglycinin subunits, respectively.
