Construction of a high-density genetic map and mapping of a spike length locus for rye.

ABSTRACT: Genetic maps provide the foundation for QTL mapping of important traits of crops. As a valuable food and forage crop, rye (Secale cereale L., RR) is also one of the tertiary gene sources of wheat, especially wild rye, Secale cereale subsp. segetale, possessing remarkable stress tolerance, tillering capacity and numerous valuable traits. In this study, based on the technique of specific-locus amplified fragment sequencing (SLAF-seq), a high-density single nucleotide polymorphism (SNP) linkage map of the cross-pollinated (CP) hybrid population crossed by S. cereale L (female parent) and S. cereale subsp. segetale (male parent) was successfully constructed. Following preprocessing, the number of 1035.11 M reads were collected and 2425800 SNP were obtained, of which 409134 SNP were polymorphic
