“…The availability of a larger number of seeds per pollination/cross and the presence of genetic mechanisms such as male sterility (tomato, chili, capsicum, onion, and cole crops), gynoecism (cucurbits, particularly cucumber and bitter gourd), and self-incompatibility (cole crops) offer ample opportunities not only to exploit heterosis but also to drastically minimize the cost of hybrid seed production. Advancements in techniques such as transgenics, gene editing, QTL mapping, genomics, and genome-wide association studies (GWASs) are being employed to predict heterosis in different vegetable crops [ 2 , 3 , 4 , 5 , 6 ] and tobacco (Zejun). However, the existing published research on the genetic mechanisms and the role of genes in defining important plant characteristics is limited.…”

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.
