The electrophoretic characteristics were investigated of the cytoplasmically controlled large subunit of ribulose 1,5-diphosphate carboxylase in the euplasmic lines T. monococcum, T. aestivum 'Chinese Spring' and T. spelta var. duhamelianum, 30 alloplasmic lines of T. aestivum 'Chinese Spring' and six alloplasmic lines of T. spelta var. duhamelianum. Lines with cytoplasm from diploid Triticum and most Aegilops species, including Ae. bicornis and Ae. sharonensis, had L-type subunits, whereas those with cytoplasm from all the polyploid Triticum species, Ae. speltoides, Ae. aucheri and Ae. longissima had H-type. Thus, section Sitopsis of Aegilops exhibits interspecific heterogeneity.
