Abstract

Although tulip is one of the most important bulbous crops worldwide, the genetic background of most cultivars is unclear at present. The purposes of this study are to investigate genetic diversity and to identify the genetic structure and relationships among tulip cultivars. A total of 236 polymorphic single nucleotide polymorphisms (SNPs) were obtained from 'Kees Nelis' and 'Cantata', from which 121 SNPs with a minor allele frequency above 0.1 were selected for genetic analysis. The total observed heterozygosity (Ho) among the 72 accessions was 0.35, Ho of cultivar groups ranged from 0.22 (Tulipa fosteriana) to 0.43 (Tulipa gesneriana x T. fosteriana hybrids). Rather small genetic distances were found among T. gesneriana cultivar groups which are defined according to flowering time and morphology. In both PCoA (principle coordinate analysis) and STRUCTURE analysis, the 72 accessions were separated into three clusters (F-ST =0.208, P
