| Summary, etc. | Sweet potato (Ipomoea batatas (L.) Lam) is one of the major tuber crops<br/>in Asian countries including India, yet the interrelationship and genetic variability<br/>among the cultivar and its crop wild relatives remain unclear. The present study<br/>utilised 12 simple sequence repeats (SSR) marker for analyse the degree of<br/>genetic diversity and relationship within and between 20 sweet potato accessions,<br/>23 wild Ipomoea species and two Merremia species.<br/>The SSR primers produced 84 polymorphic alleles within the range of<br/>105-393 bp. That showed an average polymorphism of 94.5%. The average PIC<br/>value of 0.67 showed that all the primers were polymorphic in nature. Similarity<br/>coefficient based dendrogram and PCA scatter plot clearly differentiated all the<br/>cultivars and wild species. This dendrogram helped to identify the close<br/>relationship of cultivars with I. triloba and I. trifida at a similarity index of 0.75.<br/>The dendrogram based on the SSR molecular data shows high degree of<br/>genetic variability within and between hexaploid sweet potato and diploid wild<br/>species, whereas lower within the cultivars, which shows that there is a high level<br/>of genetic diversity exist within the Ipomoea species.<br/>The results supported the current taxonomical position of M. dissecta as<br/>Merremia species whereas opposed the taxonomical position of M. vitifolia as<br/>Merremia as this study revealed more similarity to Ipomoea than Merremia<br/>species. The similarity coefficient varied from 0.37 to 0.96 indicating high<br/>variability in the genotypes that were included for the present investigation. |
