AbstractAnalysis 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-Fl, ADH-F2, ADH-l,ADH-2, ADH-3, ADH-Sl 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 4Ac(, 4BL and 4DS.A live subunit forming dimer hypothesis is postulated to explain the newly reported seven isozyme pattern.Subunits a, S and 6 are coded by chromosome arms 4Aa, 4BL and 4DS respectively, and the newly postulated E and y are coded also by chromosome arm 4BL.
