Abstract

Abstract: Breeding for cultivars with elite fruit shape and umami taste traits is an important objective of bottle gourd breeders. In this study, we examined the genotypes of 4 Zhepu bottle gourd cultivars at 16 known SNPs associated with umami taste and 37 SNPs for fruit shape by using a multiplex PCR technology. We found Zhepu No.1 has 6 alleles improving free Glu content and 1 allele for elite fruit shape, Zhepu No.9 harbored 5 alleles improving free Glu content and 2 alleles for elite fruit shape, while Zhepu No.6 and Zhepu No.8 both contained 4 free Glu content-improving alleles and 11 elite fruit shape alleles. Our study preliminarily reveals the genotypic basis of the excellent fruit shape and peculiar umami taste in several Zhepu bottle gourds, which will facilitate stacking these traits with other favored agronomical traits by marker assisted selection.
