Two chlorophyll extranuclear mutants (en: chlorina-6 and en: chlorina-7) from the collection of chlorophyll mutant sunflower South Federal University crossed as maternal forms with mutants of the same type (n:chlorina-3 and n:chlorina-5), with only recessive nuclear control of chlorophyll defects. All F1 hybrids had a mutant yellow-green color of the leaves, not differing in content of chlorophylls and gabitusa indicators from maternal forms of en: chlorina. In the F2 had viable mutant plants xantha type (combined form). It is shown that in mutants of xantha type indicators gabitusa and contents in leaves of chlorophylls far below the corresponding indicators of mutant parental forms. Obviously, in this case, combining in one plant mutant genetic systems of plastids and nucleus, increased chlorophyll defects. Obtained forms are a good model for the study of interactions between nuclear genome and plastome.
