“…This phenomenon was first described by Koelreuter in 1764 [ 64 ] and is reported to occur in a wide range of vegetable crops such as cabbage, cauliflower, tomato, etc. Darwin [ 65 ] discussed SI for the first time, while significant information on genes and gene products regarding SI trait expression was made available by Dodds et al [ 66 ]. This mechanism implies the inability of viable and functional pollen grains to fertilize ovules carrying similar S-alleles and the inhibition of self- and sib fertilization in a few plant species.…”

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.
