“…The map contained ten LGs with 477 markers, corresponding to the ten chromosomes of B. rapa (Figure 2). The map length of 1,149.1 cM resolved in this study was similar to that of previously reported B. rapa maps (Choi et al, 2007;Kim et al, 2006;Suwabe et al, 2006;Yu et al, 2009). In the present study, 56 KS SSR markers were mapped.…”

“…Further, with the advent of different types of molecular markers, several genetic maps have been constructed which helped to study the genome organization and evolution in relation to other Brassica species and with the Arabidopsis thaliana, the closest relative model plant of Brassicaceae family (Choi et al, 2007;Kim et al, 2009;Snowdon and Friedt, 2004;Suwabe et al, 2006). The development of genetic maps in Brassica using different molecular markers and mapping populations derived from different parental crosses helped to map quantitative trait loci (QTL) for root morphology (Lu et al, 2008), downy mildew (Yu et al, 2009), flowering time and leaf morphology Lou et al, 2007), hairiness and seed coat color ) and glucosinolate traits (Lou et al, 2008).…”

The inheritance of leaf and heading-related traits in Chinese cabbage (Brassica rapa ssp. pekinensis) are poorly understood since only a handful of studies of these traits are available till date. In this study, QTL mapping was done for seven leaf and heading related traits that includes gross weight, number of non-wrapper leaves, head weight, head length, head width, head length/head width ratio, and the number of head-forming leaves in 139 F3 families derived from a cross between two diverse Chinese cabbage lines, '501' with small head and '601' with large head. A total of 27 QTL spread over the nine linkage groups were identified for seven leaf and head-related traits, many of which showed major effects clustered in A2, A4, A6, and A8. The results provided a better understanding of the genetic factors controlling leaf and head-related traits in Chinese cabbage.Additional key words: clustering of QTL, EST-based microsatellite, inheritance, leaf head, QTL mapping, simple sequence repeat (SSR) Hort.

“…Thirty-six core primers were identified; these primers should have more than two polymorphic bands for establishing the molecular ID of inbred line (Table 2) (Suwabe et al, 2002(Suwabe et al, , 2003Lowe et al, 2004;Ge et al, 2005;Piquemal et al, 2005;Yu et al, 2009;Pino Del Carpio et al, 2011;Gao et al, 2012;Zhang et al, 2013;Sui et al, 2014). The primers were synthesized by Boshi Biological Technology Co., Ltd. in Harbin, China.…”

ABSTRACT. Chinese cabbage is an important cruciferous vegetable in China. The differences in the morphology and other characteristics of the different varieties of Chinese cabbage are generally caused by their different genes. Using the simple sequence repeat (SSR) DNA molecular markers is an effective way to identify different genotypes. The identification of a genetic relationship is a key point in the breeding process, and it plays an important role in guiding parent selection and breeding of high-yield varieties. Moreover, the establishment of genomic fingerprints is significant for plant variety protection. Three to five SSR sites were selected from each of the 10 Chinese cabbage chromosomes on the basis of the abundance of SSR loci on them. According to the differences in the SSR polymorphic bands, a genomic fingerprint comprising 36 different loci was established in the 20 main inbred lines of Chinese cabbage, and this fingerprint was converted digitally into a molecular ID with 36 numbers based on the 36 SSR sites. The utility of this core set SSRs was demonstrated in 20 main inbred lines of Chinese cabbage, which could be placed into six clusters that were 2 X.X. Zhang et al. Genetics and Molecular Research 16 (1): gmr16019144 largely consistent with previous classification based on morphology data. Moreover, the molecular ID of an F1 hybrid can be deduced from its parents molecular IDs, and its purity can be determined by selecting one or two SSR loci from the 36 different loci.
