Abstract
In greenhouse studies of three alloplasmicwheat series, plant height, Xowering date and yieldper plant were least aVected when the native cytoplasmwas replaced by donor cytoplasm of the Triticum–Aegilops complex than when replaced byHordeum chilense cytoplasm. On the other hand, signiWcantdiVerences for seed lutein content were foundbetween euplasmic controls and their respective alloplasmiclines in all the alloplasmic lines studied,underscoring the important role of the cytoplasm todetermine the seed carotenoid content. Both T. aestivumsubesp. macha and Ae. squarrosa cytoplasmsincreased the lutein content. They may be the mostuseful sources of cytoplasmic variability for broadeningthe genetic diversity of wheat for seed carotenoidcontent since both cytoplasm types do not produceany detrimental eVect on agronomic traits, as previouslyreported by other researchers. These Wndingsdemonstrate the role of the nuclear x cytoplasm interaction in the accumulation of carotenoids inwheat.
