Aegilops squarrosa strains collected in Pakistan, Afghanistan and Iran during the Kyoto University Scientific Expedition to the Karakoram and Hindukush in 1955 have been studied morphologically and physiologically in the experimental fields and laboratories of Kyoto and Misima in 1956 and 1957. Various variations in their characters have been found as listed in the following table.



From the data listed in the table, it is clear that the variations are accumulated in Iran, especially in the Elburz region. Hence Iran is considered to be the centre of diversity of Aegilops squarrosa.
