title: Investigation of diversity in Aegilops biuncialis and Aegilops umbellulata by A-PAGE.
abstract: Aegilops species, wild relatives of wheat, are one of the important genetic resources in wheat breeding. In this study 13 populations of Aegilops biuncialis along with 2 populations of progenitor species Aegilops umbellulata were analysed in six replications using of acid polyacrylamide gel electrophoresis. The results showed that TN-01-293 population had a high gluten and grind quality because of high percentage of γ-45.31 and γ-43.5 (high gluten quality index) in the observed band. Also, Ahar population from A. biuncialis was introduced to light gluten because of low percentage of γ-45.31 and γ-43.5 bands of quality. All studied populations can be used in breeding programmes for improving quality of bread wheat because of lack of γ-42 and γ-40 bands (low quality indices) and including high frequency of band in ω region. Through using PopGen 1.32 software, diversity is estimated . The maximum value of genetic diversity among populations resulted 49%.
