Abstract
Zymogram phenotypes of coleoptile, root and leaf esterases (ESTC, ESTR and ESTL); root acid (ACPH) and alkaline (ALK) phosphatase in wheats (Triticum) with A,D,AG,AB and ABD genome constitutions, wheatgrass (Elytrigia intermedia )and the two types of wheat- wheatgrass octoploids were analyzed, h was found that the wheatgrass chromosomes in one of the three genomes, which are, to a certain extent, homologous to the chromosomes of G geno- me could be carried by type Ⅰ wheat-wheatgrass octoploid(i.e. Zhong 2), and the wheatgrass chromosomes in another genome, which are, to a greater extent, homologous to the chromosomes in A genome might be carried by type Ⅱ wheat-wheatgrass octoploids (termed Zhong 3,4 and 5).
