The invention provides processes for marker assisted selection of common beans expressing volatile compounds that provide flavor traits associated with single nucleotide polymorphisms (SNPs) and/or sequences flanking SNPs, as well as allele-specific oligo sequence primers configured to anneal to related SNPs and to report the presence or absence of SNPs with fluorescent signals using a PCR assay, a KASP assay (i.e., modified PCR assay), or other molecular marker assay, e.g., SSR, capable of identifying the presence or absence of SNPs and/or portions of flanking sequences of the SNPs, all of which enhances selection efficiency in common bean breeding strategies.
