Forty seven resistant and susceptible to late blight Indian potato cultivars were used to assess genetic diversity present among them. A set of 24 microsatellite markers applied which generated 193 alleles with an average of 7.04 per loci and 4.10 per genotype. Eight alleles were specific to resistant cultivars, whereas 11 were specific to susceptible. Genetic diversity among the moderately resistant genotypes was found to be higher than the susceptible and resistant ones. The cluster analysis grouped the cultivars into 2 main and 4 sub clusters with late blight resistant genotypes distributed across the clusters. The diverisity among the genotypes was very high; however, diversity within groups viz., resistant, moderately resistant and susceptible was found to be very low (6%). The findings of the study would be of great help to the breeders in selecting genotypes for developing improved varieties of potato.

Uncovering the genetic basis and optimizing the late blight tolerance trait in potatoes (Solanum tuberosum L.) are crucial for potato breeding. Late blight disease is one of the most significant diseases hindering potato production. The traits of late blight tolerance were evaluated for 284 potato cultivars to identify loci significantly associated with the late blight tolerance trait. Of all, 37 and 15 were the most tolerant to disease, and 107 and 30 were the most susceptible. A total of 22,489 high-quality single-nucleotide polymorphisms and indels were identified in 284 potato cultivars. All the potato cultivars were clustered into eight subgroups using population structure analysis and principal component analysis, which were consistent with the results of the phylogenetic tree analysis. The average genetic diversity for all 284 potato cultivars was 0.216, and the differentiation index of each subgroup was 0.025–0.149. Genome-wide linkage disequilibrium (LD) analysis demonstrated that the average LD was about 0.9 kb. A genome-wide association study using a mixed linear model identified 964 loci significantly associated with the late blight tolerance trait. Fourteen candidate genes for late blight tolerance traits were identified, including genes encoding late blight tolerance protein, chitinase 1, cytosolic nucleotide-binding site–leucine-rich repeat tolerance protein, protein kinase, ethylene-responsive transcription factor, and other potential plant tolerance-related proteins. This study provides novel insights into the genetic architecture of late blight tolerance traits and will be helpful for late blight tolerance in potato breeding.
