Finally, cempedak cultivars with the same names did not always share the same genetic fingerprint. We found a distinct genetic cluster for cempedak from Borneo as compared to cempedak from Peninsular Malaysia. Genetic diversity was generally higher in bangkong than in cempedak. We show that cempedak and bangkong are sister taxa and distinct genetically and morphologically, but the directionality of domestication origin is unclear. We also analyzed key vegetative characters that reportedly differentiate cempedak and bangkong. We conducted haplotype network analyses on the trnH-psbA region in a subset of these samples. Using data from 12 microsatellite loci, we assessed the genetic diversity and genetic/geographic structure for 353 cempedak and 175 bangkong accessions from Malaysia and neighboring countries and employed clonal analysis to characterize cempedak cultivars. silvestris Corner) to address questions regarding the origin and diversity of cempedak.
Here we performed molecular characterization of cempedak and its putative wild relative bangkong ( Artocarpus integer (Thunb). Cempedak is a significant crop in Malaysia but underutilized elsewhere. Underutilized crops and their wild relatives are important resources for crop improvement and food security.
