Abstract

Although the endosperm storage protein of hexaploid triticale have alreadybeen analysed, the allelic diversity of glutenins and secalins remains to bedescribed. Analysis, by SDS-PAGE, of about one thousand F2 seeds fromten triticale crosses allowed the inheritance of these storage proteins to bestudied in order to determine their allelic forms and to assign them toparticular chromosomes. Two new alleles encoding HMW subunits ofglutenin and five new alleles encoding HMW subunits of secalin weredetermined at Glu-B1 and Glu-R1 loci respectively. In additionto the three allelic forms of 75K gamma-secalins encoded at Gli-R2and previously reported, a null form was found. A nomenclature for theseproteins and their corresponding alleles was suggested. The composition ofB-LMW glutenin subunits of hexaploid triticale was described and allelicforms were determined: Five alleles were encoded at Glu-A3 andseven at Glu-B3 including one and two new allelic formsrespectively.
