QTL for pitted scab, hollow heart, and tuber calcium identified in a tetraploid population of potato derived from an Atlantic × Superior cross

Abstract Common scab, calcium deficiency, and internal tuber defects, such as hollow heart, have severe negative impact on the marketable yield profitability of potato ( Solanum tuberosum L.) farmers. The present study was conducted to detect quantitative trait loci (QTL) controlling these traits. A tetraploid linkage map constructed using 808 single nucleotide polymorphisms (SNPs) from SolCAP 8300 Infinium Potato Array 151 genotypes an F 1 population generated a cross between cultivars with divergent traits, Atlantic Superior. is susceptible scab has high incidence heart low calcium. Conversely, Superior resistance This phenotypically evaluated 2009 2012. Seven QTL regions explained pitted severity; two chromosomes 3 11 Atlantic, five 1, 2, 5, 6, 10 were identified. Also, six that variation detected; four located 4, 7, 8 Atlantic; one chromosome In addition, identified for heart; 5 three 3, 12 These can be further studied develop markers marker‐assisted selection.
