A total of 165 potato genotypes were analysed using two well-known potato SSR markers (STU6SNRN and STIIKA). The multicoloured flesh potato hybrids and interspecific somatic hybrids-derived progenies were for the study conducted at ICAR-CPRI, Shimla during 2019-20. The objective of this study was to develop SSR profiles of potato (Solanum tuberosum L.) hybrids for genetic fidelity purpose. This is the first ever report in India towards widening the genetic base of potato by exploitation of interspecific somatic hybrids. This study concludes successful exploitation of interspecific potato somatic hybrids possessing high resistance to late blight and developed promising clones with linked ISSR alleles for genetic fidelity and breeding purposes. Eight promising advanced hybrids of BC1-C 4 progenies (Kufri Garima x Bulk pollen: MSH/14-7 Kufri Gaurav x P2: MSH/14129 and -131 for yield enhancement P8 x Kufri Jyoti: MSH/14-112, -113, -115, -122 and -123 for late blight resistance and dry matter) were identified. The BC1-C 2 progenies were profiled by ISSR markers and alleles linked to late blight resistant somatic hybrid parent P8 and their progenies (P8 × Kufri Jyoti) were identified. TPS-raised seedlings were advanced to back-cross progenies clones (BC1-C 1, BC1-C 2, BC1-C 3 and BC1-C 4) during the five years based on tuber traits in field trials and field resistance to late blight. tuberosum) and true potato seed (TPS) were produced. pinnatisectum) were back-crossed with potato varieties (S. Previously developed potato somatic hybrids (considered as F1 being protoplast fusion product between Solanum tuberosum dihaploid ‘C-13’ + S. Elite hybrid progenies of late blight resistant potato somatic hybrids were developed through hybridization with common potato varieties, and also linked ISSR markers were identified with resistant parent/progenies.
