Abstract
Two wheat/Thinopyrum amphiploids, wheat/T. bessarabicum and wheat/T. elongatum were crossed together and meiosis was studied in the F1 hybrid. The data show that although the wheat chromosomes pair fully, those of the two diploid Thinopyrum species rarely pair, 21 bivalents plus 14 univalents being the modal configuration. The genome symbols E for T. elongatum and Eb for T. bessarabicum are proposed.Key words: Thinopyrum elongatum, Thinopyrum bessarabicum, genome relationship.This publication has 3 references indexed in Scilit:
