Each of 208 hexaploid accessions carried the same Est-1 alleles except accessions of T. compactum var. rubriceps, each of which carried an Est-B1 or Est-D1 electrophoretic mobility variant (560).
Among 208 hexaploid accessions, an apparent Est-B2 null allele occurred frequently in accessions of T. macha and T. sphaerococcum and occasionally in accessions of T. compactum.. The allele was not observed in T. aestivum and T. spelta accessions (560).
One accession carrying an apparent Est-B3 null allele and one carrying an apparent Est- D3 null allele were found among 208 hexaploid accessions (560).
A 7AS locus encoding three esterase isozymes in immature grains has been reported
(566).
