The inheritance of the proteins in the first zone (Rf 0.66-Rf 1.00) appears to be controlled by a single locus Av-1 with five alternate alleles Av1`1.0`, Av1`0.83`, Av1`0.70`, Av1`0.67`, and Av1`0.66/0.70` designating the Rf values of proteins present in Lancer, Bates, Fidler, Ogle, and Astro, respectively. The Coker 716 phenotype (proteins at Rf 0.66 and 0.83) may be a sixth alternate allele at the Av1 locus. Segregation tests for allelism revealed the presence and absence of a protein migrating at Rf 0.64 in crosses segregating at the Av-2 locus and Rf 0.60 for Av-3 locus segregation. The proteins at Rf 0.58 and 0.61 segregated as alternate alleles in the crosses Ogle/Bates, Ogle/Clintford, and Ogle/Fidler and were designated Av4`0.58` and Av4`0.61`, alternate alleles at the Av-4 locus.
