Genetic Diversity Analysis of Hybrids between Amorphophallus Yunnanensis and Amorphophallus Dunnii
Amorphophallus species have been considered as an important cash crop in Southwest China for the wild usage of glucomannan in food and medicinal fields.Individuals of Amorphophallus yunnanensis,A.dunnii,and their hybrids were analyzed using SSR markers to determine their genetic diversity and relation-ship to help with the utilization of hybrid resources.The results showed that no significant differences in ge-netic indices between hybrids and parents.The highest number of alleles was found in A.yunnanensis and hybrids,while A.dunnii had the highest values in the Shannon index,observed,and expected heterozygos-ity,attributed to the high genetic diversity in wild parental species.Additionally,a unique genetic cluster formed with hybrids was identified using SSR markers,and the hybrids were found to be more closely relat-ed to A.yunnanensis than to A.dunnii.The maternal species,A.yunnanensis,may have a greater genetic impact on the hybrids.These findings provide new insights for future molecular associate breeding of Amor-phophallus resources.
