Chinese cabbage varieties with orange inner leaves are of interest due to their attractive appearance and high carotenoid content. Previously, a recessive locus, Br-or, that confers this trait was mapped to linkage group A09 in Brassica rapa, and Bra031539 was identified as the candidate gene. We used a backcross population consisting of 1,392 individuals… (More)
The purple-leaf phenotype in Chinese cabbage is due to the accumulation of anthocyanin. To investigate the pattern of inheritance of this trait in Brassica rapa, F1, F2 and backcross (BC) populations were constructed by crossing 09N-742, a pak-choi inbred line that has purple leaves, with a green-leaved Chinese cabbage inbred line, 09-680. Using a… (More)
Verticillium wilt disease has become increasingly serious in many regions in China over the past few years. In this study, the widespread pathogen was identified as Verticillium longisporum (V. longisporum) by mt-SSU rDNA and cytochrome b sequence analysis. By using the primer pair HW1-F/HW1-R, which was designed based on the V. longisporum-specific… (More)
By cultivating tipburn-susceptible plants in modified Hoagland’s medium containing of gradient exogenous calcium (Ca2+), we have shown that Ca2+ deficiency is one of the main causes of tipburn in Chinese cabbage (Brassica rapa L. ssp. pekinensis). The effect of endogenous plant Ca2+ concentrations on tipburn was also studied in a doubled haploid (DH)… (More)
The original paper of this article unfortunately contains error at the names of authors. Authors " Jiao Wang Fenglan Zhang " should be " Jiao Wang " and " Fenglan Zhang " , that is two names, not one. Correct affiliations are also presented herewith.
Specific-locus amplified fragment sequencing is a high-resolution method for genetic mapping, genotyping, and single nucleotide polymorphism (SNP) marker discovery. Previously, a major QTL for downy mildew resistance, BraDM, was mapped to linkage group A08 in a doubled-haploid population derived from Chinese cabbage lines 91–112 and T12–19. The aim of the… (More)
