“…The total glucosinolate content and the individual glucosinolates ( µ mol g −1 dry matter) were analyzed by high performance liquid chromatography (HPLC). The method was adopted from an official method of the European Commission (1990) (Rosa, 1999; Spinks et al, 1984) with minor modifications (Jesske et al, 2012). The internal standard glucotropaeolin was isolated according to Thies (1988).…”

The genetics of seed compounds is complex because seed quality traits might be exclusively determined by the genotype of the female parent or, depending on the genotype of the embryo, may also be affected by the genotype of the pollen parent. For many quality traits of oilseed rape (Brassica napus L.), the influence of the pollen parent is not well known. In this study, two male sterile lines (female parent) were pollinated by 10 genotypes (pollen parent) differing largely in seed quality. Field experiments were conducted at three locations in Northern Germany, with two replications in 1 yr. Pollen parents were sown in plots and 10 male sterile plants from each female parent were hand planted into the center of each plot. Seeds were harvested from pollen parents and from the interplanted female parents. Seeds were analyzed for oil, protein, and sinapic acid esters by near‐infrared reflectance spectroscopy; for glucosinolate and tocopherol content by high‐performance liquid chromatography; and for fatty acid content by gas liquid chromatography. Earlier results were confirmed in that fatty acid composition is dependent on the embryo genotype and is therefore largely influenced by the pollen parent. Significant pollen parent effects were also observed for oil content, indole glucosinolate, sinapoylglucose, total sinapic acid ester, and γ‐tocopherol contents. The F1 seed quality was positively correlated with the pollen parent seed quality. In conclusion, not only the fatty acid composition but also other seed quality traits such as oil content are influenced by the genotype of the pollen parent. This should be considered when analyzing open pollinated plants.

“…Also, in field trials conducted in regions with less strong climate differences than the regions in the study of Si et al (2003), significant effects of the environment on oil content in rapeseed were observed. For example Girke et al (2012b) and Jesske et al (2013b) detected significant effects of the different environments on oil content in resynthesized rapeseed lines tested in field trials that were conducted within Germany, respectively within Germany and the UK. In this study the field trials were actually conducted only in a small region of Germany, comparable to the experiments of Girke et al (2012b).…”

“…A problem in using the novel alleles of exotic genotypes is that the exotic genotypes are agronomically weak and that they are not adapted to the cultivation in Germany (Girke et al, 2012b;Jesske et al, 2013a and2013b). Moreover, the observed effects on oil content showed that novel alleles which appear to have a positive effect in one genetic background may not have the same effect in all backgrounds.…”
