| Abstract:
The eggplant yield can be reduced severely in Greece and Turkey because of the sensitivity to Verticillium wilt of the cvs cultivated in these countries. Resistant varieties could be developed by introgression of genes from the resistant wild species Solanum torvum. For this purpose the most important Greek eggplant variety ‘Langada’ was crossed to the forementioned wild species. Ovules, 15–27 days after pollination (DAP) were cultured in a modified MS medium at 24°C and 16 h photo period. Fifty days later, the ovules were opened and the interspecific embryos were cultured in the same medium. The germinated interspecific embryos were grown for 50 days and then they were transplanted into pots containing soil-peat-perlite in a rate 1:2:1 w/w. The leaf and flower morphological traits were measured. Leaf length, width, petiole length, flower size, stamen and style length, were smaller than those of the parents. The number of leaf lobes, the petals, sepals, sepals length, the stamens number and length and the spine location resembled the wild parent (S. torvum). In contrast, anthocyanin of the main stem, flower colour, and spine colour resembled the cultivated species (S. melongena). The number of flowers per inflorescence were intermediate between the two parents. | |
