“…While the treatment of plant age and level of sweetness has a partially negative dominant potential ratio, the treatment of fruit length and fruit thickness has a partially positive potential ratio. According to Frizzell (2013), partial dominance or incomplete dominance results from crosses in which each parent contribution is genetically unique and gives rise to progeny with an intermediate phenotypic appearance or similar between the two. According to Krisnawati and Adie (2022), the overdominance phenomenon in the crossing performance of a population will be different due to selection, and there will be an increase in the homozygosity of alternative alleles in the population to maximize heterozygosity and population crossing performance.…”

Crosses between local lombok cantaloupe and melon have produced the first progeny (F1). The F1 have a similar appearance to their parents. This study used two similarity assessments based on qualitative and quantitative traits. Qualitative characters are said to have similarities if their phenotypic appearance resembles one or both parents. The similarity of qualitative characters is visually observed using the munsell plant tissue color book and penetrometer. Meanwhile, the quantitative characters are said to have an appearance resembling one or both parents if the standard error line at the histogram between parents and offspring overlaps. In addition, analysis of gene action, heterosis, heterobeltiosis, and the maternal effect was carried out on quantitative character to obtain genetic information for producing superior local lombok cantaloupe varieties. The results of this study showed several changes in the appearance of F1 in qualitative and quantitative characters. The qualitative characters of F1 resemble the female parent, while the quantitative characters do not resemble both parents. Genetic information about potential ratio, heterosis, heterobeltiosis, and maternal effect varied. Gene action is dominated by potency ratio partial dominance and overdominance. Heterosis occurred in all treatments, while heterobeltiosis did not occur in all treatments. The maternal-effect was obtained on fruit weight, fruit diameter, and fruit length characters.
