Glucosinolates and other seed quality traits of resynthesized Brassica napus L. derived from domesticated and wild Brassica taxa

Abstract Resynthesized Brassica napus L. genotypes can be used to increase the variation in the rapeseed genepool. We evaluated seed quality parameters of resynthesized lines that originated from crosses of oilseed B. rapa L. with domesticated (vegetable) B. oleracea L., and resynthesized lines that were obtained from crosses of B. rapa oilseed cultivars with wild B. oleracea ssp. oleracea and with seven Brassica species from the B. oleracea group (B. bourgeaui Kuntze, B. cretica Lam., B. incana Ten., B.hilarionis Post, B.montana Pourret, B.rupestris Raf., B.villosa Bivona-Bernardi). Twenty-three resynthesized lines and ten cultivars were grown in 1 year and six locations in Germany and the United Kingdom. The mean seed oil, phytosterole, and sinapine contents of the resynthesized lines were lower than in the cultivars, while protein, glucosinolate, and erucic acid contents were higher, respectively. Nearly all resynthesized lines derived from wild Brassica taxa showed a glucosinolate pattern very different from all cultivars and from nearly all resynthesized lines obtained from crosses with domesticated B. oleracea. The newly developed wild Brassica based resynthesized lines represent an immense source of genetic variation that has not been used to full capacity up to now..
