Genetic control of beta;-amylase isozymes in common or hexaploid wheat (Triticum aestivum)

摘要

Examination of seeds of parents and F1and F2hybrids of the crosses 'Vilmorin 23'ensp;times;ensp;'61.5.3.2.' and 'Fournil' times; 'Yaktana' and the reciprocal crosses showed that the C1, C2, and C3components of the beta;-amylase zymogram, determined by polyacrylamide slab electrophoresis are each controlled by a pair of alleles. From the results of the second cross 'Fournil' times; 'Yaktana,' a linkage study between these genes was undertaken. From previous work, we know that components C1are located on chromosome 4ensp;Abeta;and C3on chromosome 4ensp;DL. We conclude that genes for C1and C2components are tightly linked on the same chromosome (4ensp;Abeta;).
