“…The development of high volumes of seeds was possible because of the lack of the physiological barriers between B. napus and B. rapa, physical proximity and the flowering synchrony of both components (Anonymous 2002;Bing et al 1996;Elling et al 2010). The utilization of three highly selfcompatible Chinese cabbage inbred lines (KW, HG and MR) for the interspecific hybridisation with rapeseed allowed for the efficient cross-pollination at the open flower stage in consecutive BCs.…”

“…This CMS sterility has also been widely used to produce commercial hybrids of B. oleracea vegetables (Prakash et al 2009). Interspecific crosses attempted by plant breeders and geneticists between B. napus and B. rapa can occur readily owing to the high degree of relatedness, albeit with varying degrees of difficulty (Elling et al 2010). Natural hybrids were found in fields where species are in physical proximity and have flowering synchrony (Anonymous 2002;Bing et al 1996;Jorgensen and Andersen 1994).…”

“…Chinese cabbage (B. rapa ssp. pekinensis L.) is one of the most popular vegetables with a worldwide distribution, available for consumers year-round as a valuable source of carbohydrates, proteins, dietary fibre, vitamins A, C, K and B6, minerals, and glucosinolates (Dickson 2007). In Poland, the production area of Chinese cabbage ranges from 5000 to 7000 ha and depends entirely on F 1 cultivars supplied by foreign seed companies.…”

Interspecific hybridisation of cytoplasmic male-sterile rapeseed with Ogura cytoplasm and Brassica rapa var. pekinensis as a method to obtain male-sterile Chinese cabbage inbred lines

During 2011-2014, three self-compatible Chinese cabbage inbred lines (Brassica rapa, genome AA 2n = 20) were sexually hybridised with cytoplasmic male-sterile (CMS Ogu-INRA) and fertile lines of rapeseed (Brassica napus var. oleifera, genome AACC 2n = 38). Interspecific F 1 hybrids and their consecutive back-crosses (BCs) toward B. rapa were obtained, and their morphological and commercial characteristics, as well as their ability for generative propagation, were analysed. Cytometric and morphological analyses confirmed the interspecific character of the F 1 hybrids in comparison with B. napus and B. rapa parental lines. All interspecific F 1 hybrids had intermediate morphological characteristics typical of both parental components in the generative and vegetative stages. The F 1 hybrids of CMS B. napus 9 B. rapa were sterile, as were those of fertile B. napus 9 B. rapa. Good seed productivity from CMS B. napus 9 B. rapa and consecutive back-cross 1 (BC 1 )-BC 3 generations with Chinese cabbage as the recurrent parent was obtained. Plants of the BC 1 generation of CMS B. napus 9 B. rapa were sterile and had highly diversified morphological characteristics, both in the vegetative and generative phases. The BC 3 generation of CMS B. rapa was also sterile and more uniform than BC 1 , with good vigour and most of the typical Chinese cabbage agronomic traits. As a result, a collection of Chinese cabbage genotypes having the CMS trait, which is valuable for the breeding of commercial F 1 hybrids, was obtained for the first time in Poland.

The commercial use of genetically modified (GM) organisms is regulated in the EU by law. Thus, monitoring the environmental effects of GM organisms after placement on the market is a mandatory task of the respective consent holder. Since many relevant monitoring procedures lack standardisation, the Association of German Engineers (VDI) has commissioned expert groups with the development of guidelines covering appropriate methodologies. As part of this project, the VDI Guideline 4330 Part 10 was set up (Bleeker et al. 2011) describing a standardised procedure for floristic mapping of spontaneously occurring (non-cultivated) GM crops, their wild potential crossing partners and their hybrid offspring. Areas to be mapped are those where such plants are expected to be found, e.g. on former fields and in the vicinity of current or former fields of GM plants. In the case of transportation, processing or use of GM plants as animal feed, these are areas surrounding the processing, storage, handling and usage facilities, including access routes to and from the facilities. The concept of adverse environmental effects caused by the dispersal and outcrossing of GM plants is briefly introduced. The necessity of floristic mapping in the context of post-market environmental monitoring of GM plants is demonstrated taking oilseed rape as an example. The development of the Guideline VDI 4330 Part 10 is described and its contents are summarised. An important conclusion on the relevance and efficiency of the floristic mapping method is that strict standardisation ensures a high level of EU wide reproducibility and comparability of the results.
