Non-heading Chinese cabbage [Brassica rapa L. ssp. chinensis (L.) Hanelt] is one of the most popular leafy vegetables. Despite the economic importance of non-heading Chinese cabbage, little attention has been given to its cytogenetic profile. This study reveals the karyotype of non-heading Chinese cabbage. Fluorescence in situ hybridization (FISH) with 45S(More)
A significant fraction of the nuclear DNA of all eukaryotes is comprised of simple sequence repeats (SSRs). Although these sequences are widely used for studying genetic variation, linkage mapping and evolution, little attention had been paid to the chromosomal distribution and cytogenetic diversity of these sequences. In this paper, we report the(More)
Non-heading Chinese cabbage encompasses a wide diversity of morphotypes, like the well-known Pak-choi, Wu ta cai, Cai xin, Tai cai, and Fen nei cai. Despite recent developments in re-sequencing which results in the detection of SNPs, insertions, deletions and copy number variants, there has been no systematical cytogenetic characterization of different(More)
