Abstract

The glucosinolate (GSL) content and -profile of a complete series of nine disomic rapeseed-radish chromosome addition lines (2n = 38 + 2, a to i) was estimated and compared to that of radish as donor and rapeseed as recipient of the alien chromosomes. Modification of identical genetic rapeseed background by single radish chromosomes allows the assignment of GSL biosynthesis steps to individual radish chromosomes. Addition line a was found to have a five times higher aliphatic GSL content than the rapeseed parent. Radish-specific GSLs, glucoraphenin and glucoerysolin, were synthesized exclusively in addition line g. Addition line i produced sinigrin, not detectable in both parents. The variations in GSL content are not correlated with resistance against beet cyst nematode (Heterodera schachtii Schmidt).
