Pollen fertility differences in the progenies obtained from a cross between eggplant (Solanum melongena L.) as a seed parent and eggplant cytoplasmic substitution lines as pollen parents

To the best of our knowledge, there is no report about pollen fertility progenies developed using eggplant (Solanum melongena L.) as a seed parent and cytoplasmic substitution lines parents. Pollen these very important to use restorer line in eggplant’s hybrid breeding program. In this study, was investigated for which were produced S. ‘Uttara’ assess fertility, stainability vitro germination ability investigated. Although nuclear genome almost identical ‘Uttara’, clear difference observed due parents having different wild Solanum cytoplasms. The functional male sterile (CMS) parent, whose cytoplasm donor kurzii, violaceum virginianum, showed release type high equal ‘Uttara’. It considered that characteristics same eggplant. On other hand, restored non-formation CMS donors aethiopicum, anguivi grandifolium, low i.e., staining 54% 35%. cause incompatibility between genome, seems be modified process continuous backcrossing under suggested complete difficult by with alloplasmic grandifolium donors. Incompatibility normal genomes cytoplasms might
