Summary Analysis of individual parts of Triticum aestivum L. and T. turgidum var. durum kernels showed two classes of alcohol dehydrogenase patterns: 1) A three banded pattern (ADH-1, ADH-2 and ADH-3) for endosperm (Ed) and 2) a seven banded pattern (ADH-F1, ADH-F2, ADH-1, ADH-2, ADH-3, ADH-S1 and ADH-S2) for embryo (E), scutellum (S) and embryo plus scutellum (E+S). The use of nullitetrasomic and ditelosomic series of Chinese Spring wheat allows alcohol dehydrogenase to be associated with arms 4Aα, 4BL and 4DS. A five subunit forming dimer hypothesis is postulated to explain the newly reported seven isozyme pattern. Subunits α, β and δ are coded by chromosome arms 4Aα, 4BL and 4DS respectively, and the newly postulated ɛ and γ are coded also by chromosome arm 4BL.
