Cytoplasms of fifteen wild Nicotianae and a male sterile cytoplasm (cms) from N. tabacum were bred into the genome of a standard Polish flue-cured cultivar Wislica. The sixteen iso-genomic alloplasmics were compared for expression of male sterility and for some traits related to field performance. In cmsN. bigelovii, N. debneyi, N. exigua, N. megalosiphonor N. suaveolens stamens were absent, in cmsN. tabacum, N. glauca, N. goodspeedii or N. undulata stamens were absent or rudimentary, in cmsN. eastii, N. glutinosa or N. plumbaginifoliastamen tissue became petaloid, in those from N. knightiana and N. raimondiithey were morphologically normal. Female organ morphology was changed in cmsN. goodspeedii, N. occidentalis, N. exigua, N. debneyior N. bigelovii, seed set was reduced only in cmsN. occidentalis. Plant height in most alloplasmics was similar to that of the fertile variety but was strongly depressed by the cytoplasms of N. glutinosa, N. eastiiand N. plumbaginifolia. Leaf area was positively affected by N. amplexicaulis, N. bigeloviiand N. undulatacytoplasms, unaffected by N. suaveolens, N. tabacumand N. glaucacytoplasms and negatively affected by the remaining cytoplasms mostly because of the narrowing of the leaf blade. Cured leaf yields from cmsN. bigelovii were higher than those of Wislica. Leaf yields from cmsN. amplexicaulis, N. suaveolens, N. glauca or N. tabacum were not affected by the alien cytoplasm, whereas those from the remaining alloplasmics were depressed to different extents. Increased incidence of PVY and white spots (mostly attributable to Cercospora sp.) were observed on many of the alloplasmics especially on cmsN. exigua and N. suaveolens(PVY) and increased white spots only on cmsN. bigelovii, N. exigua, N. occidentalis and N. undulata.
