Conventional gene analysis, monosomic analysis and telocentric method of mapping were carried out with respect to α-amylase zymogram variations of germinating seed of hexaploid wheat. The gene for Band 1(Amy 6D1) was located on 6DL with the recombination value of 11.9±2.8(%) from the centromere. Its minor allele, Amy 6D1M and null allele, Amy 6D1° were also detected in spelta duhamelianum, and Prelude, respectively. The locus for Band 2 was polymorphic, there being two alleles, Amy 6A1 and Amy 6A1M, for Band 2 major and minor, respectively. The gene for Band 3, Amy 6B1, was on 6BL with the recombination value of 19.4±3.8(%) from the centromere. On this locus, there were two other alleles, Amy 6B14′, and Amy 6B1° for Band 4′ and absence of both Band 3 and 4′, respectively. On the same chromosome was another α-amylase locus having two alleles, Amy 6B2 for Band 10 and its null allele, Amy 6B2°, distant from Amy 6B1 by the recombination value of 20.6±2.2(%). There were two alleles, Amy 4 and Amy 4M for Band 4 major and minor. Amy 7B2 for Band 14 was detected on 7B in addition to Amy 7B1 for Band 15.
