To address the complex challenges faced by our planet such as rapidly changing climate patterns, food and nutritional insecurities, and the escalating world population, the development of hybrid vegetable crops is imperative. Vegetable hybrids could effectively mitigate the above-mentioned fundamental challenges in numerous countries. Utilizing genetic mechanisms to create hybrids not only reduces costs but also holds significant practical implications, particularly in streamlining hybrid seed production. These mechanisms encompass self-incompatibility (SI), male sterility, and gynoecism. The present comprehensive review is primarily focused on the elucidation of fundamental processes associated with floral characteristics, the genetic regulation of floral traits, pollen biology, and development. Specific attention is given to the mechanisms for masculinizing and feminizing cucurbits to facilitate hybrid seed production as well as the hybridization approaches used in the biofortification of vegetable crops. Furthermore, this review provides valuable insights into recent biotechnological advancements and their future utilization for developing the genetic systems of major vegetable crops.

“…Several reports about male sterility in eggplant have been described. Genic male sterility caused by recessive nuclear genes was reported (Chauhan, 1984;Jasmin, 1954;Nuttall, 1963;Phatak and Jaworski, 1989;Phatak et al, 1991). Cytoplasmic male sterility (CMS) derived by utilizing the cytoplasms of wild Solanum species S. aethiopicum Gilo Group (S. gilo Raddi.…”

In order to develop a male sterile eggplant (Solanum melongena L.), cytoplasm substitution lines of eggplant were produced by continuous backcrossing using Solanum aethiopicum L. Gilo Group (i.e. S. gilo Raddi.) as cytoplasm donor and eggplant as nucleus donor. In the interspecific F 1 hybrids between S. aethiopicum Gilo Group and eggplant 'Uttara' and 'Senryo nigo,' only the F 1 , whose paternal parent is 'Senryo nigo' was able to make BC 1 . After the BC 1 , 'Uttara' was used as a recurrent pollen parent to grow up to BC 5 . The pollen staining ability decreased as the backcrossing generation progressed and completely disappeared in the BC 4 and BC 5 . The highest percentage of fruit set was observed in the BC 5 with about 69%. The number of seeds per fruit was observed in BC 4 and BC 5 was relatively high. These indicate that the cytoplasm of S. aethiopicum Gilo Group has no notable negative effect on the seed fertility of S. melongena. Analyses of chloroplast DNA and mitochondrial DNA of the BC 5 confirmed that all backcross progenies had the cytoplasm from S. aethiopicum Gilo Group. A new male sterile line of eggplant could be developed by utilizing the cytoplasm of S. aethiopicum Gilo Group.
