The genetic base of compactness has been an area of active research in recent years, with several genes and mutations identified to be associated with the appearance of dwarf phenotypes. Understanding the functions of these genes and the underlying mechanisms of dwarfism in cucurbit crops is essential for developing new cultivars with improved yield and fruit quality. This study presents current data on genes and mutations associated with the evolvement of compact phenotypes in cucurbit crops. The review includes examples of mutant compact phenotypes and their associated genes in representatives of the Cucurbitaceae family, such as Cucurbita maxima Duch., Cucurbita pepo L., Cucurbita moschata Duch., Citrullus lanatus (Thunb.) Matsum. & Nakai, and Cucumis melo L. The review provides up-to-date information on the genetic and molecular bases of compact phenotype formation, as well as molecular markers for detecting known genes associated with reduced plant size.

“…In bitter gourd, the functional study of genetics is considerably behind other Cucurbitaceae crops like watermelon and cucumber because of the lack of mutants ( Deng et al., 2022 ; Zhang et al., 2022 ). A long-recognized large-scale method for mutant acquisition is mutagenization using chemical or physical mutagens.…”

“…Because EMS mutagenesis is easy to control, exhibits a high mutation rate, and causes less harm to plants, it was widely used in rice ( Henry et al., 2014 ), maize ( Lu et al., 2018 ), soybean ( Li et al., 2017 ), pepper ( Arisha et al., 2015 ), cabbage ( Sun et al., 2022 ), watermelon ( Deng et al., 2022 ), cucumber ( Zhang et al., 2022 ) and Gossypium hirsutum L ( Lian et al., 2020 ). EMS concentrations differ from one crop to another, and a suitable mutagen concentration can be used to achieve the desired effect.…”

Although a few studies have elucidated the creation of bitter gourd mutants, the suitable concentration and duration of ethyl methanesulfonate (EMS) mutagenesis have not been determined. In this study, mutant collection was conducted to create new germplasms and widen genetic diversity. By employing the seeds of the inbred line Y52 as the mutagenic material, EMS as the mutagen, and the suitable mutagenic conditions for bitter gourd seeds (EMS concentration 0.2%, mutagenic time 10 h), we mutated 10,000 seeds and acquired 3223 independent M1 lines. For the randomly selected 1000 M2 lines, 199 M2 lines with visible phenotypes were found, and 167 M2 lines were mutants of fruit shape, size, and tubercles. Furthermore, fourteen dwarf, eleven leaf color, five leaf shape, and eight meristem defect mutants were discovered in this mutant collection. In addition, three lines of 1253, 2284, and 3269 represented recessive mutants crossed with Y52. Furthermore, the yellow leaf lines of 2284 and 3269 were not mutated at the same gene locus. This study constructed a mutant collection through innovative new germplasms and provided valuable resources for bitter gourd breeding and functional gene research.
