Introduction Prickles are often deemed undesirable traits in many crops, including roses ( Rosa sp.), and there is demand for rose cultivars with no or very few prickles. This study aims to identify new and/or validate reported quantitative trait loci (QTLs) associated stem leaf rachis prickle density, characterize the effects of functional haplotypes major QTLs, sources QTL-alleles increased/decreased density roses. Methods QTL mapping using pedigree-based analysis (PBA), haplotype were conducted on two multi-parental diploid populations (TX2WOB TX2WSE). Results discussion Twelve QTLs identified linkage groups (LGs) 2, 3, 4, 6. The located between 42.25 45.66 Mbp chromosome 3 chinensis genome assembly, individual explaining 18 49% phenotypic variance (PVE). remaining mapped minor. As several detected LG3, 6 PVE 8 17%. Also, this that ancestors R. wichurana ‘Basye’s Thornless’, ‘Old Blush’, pollen parent M4-4 common favorable alleles q ) decreased whereas ’Little Chief’ ‘Srche Europy’ source unfavorable Q TX2WOB TX2WSE populations, respectively. outcomes work complement other studies locate factors affect density. These results can also be utilized develop high-throughput DNA tests apply parental selection prickle-free cultivars.
