Abstract

SSR markers were analysed to reveal allelic variations in wild species and interspecific somatic hybrids of potato. SSR allelic profiles showed high polymorphism and distinctness in the samples. A total of 131 alleles of 13 polymorphic SSR loci were scored in 48 samples of wild species and somatic hybrids of potato. Alleles per locus ranged from 6 (STM5127/STM5114/STM1053/STI0030) to 20 (STM1052) whereas PIC value varied between 0.81 (STM5127/STM5114) to 0.94 (STM1052) in the samples. This study suggests that SSR-based genotyping and development SSR markers dataset would strengthen their utilization in identification and molecular characterization of wild species and somatic hybrids of potato.
