Genetic Mechanisms for Hybrid Breeding in Vegetable Crops

“…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.…”

“…Heterosis (also known as hybrid vigor) plays a pivotal role in vegetable breeding, leading to significant improvements in yield, quality, and earliness, which are considered the desirable outcomes when genetically distant parents are used to produce hybrid off-springs in vegetable crops. However, the selection of suitable parents is crucial for achieving these results [1]. Genetic diversity among parents enables the development of inbred lines that exhibit both good general and specific combining abilities, which are then utilized to produce promising hybrids.…”
