EN

BAC (bacterial artificial chromosome) clones from the genomic BAC library of the narrow-leafed lupin (Lupinus angustifolius) were used for cytogenetic mapping of mitotic metaphase chromosomes of that species by the BAC-FISH technique. Location of the clones, together with cytogenetic markers localised earlier by FISH (fluorescence in situ hybridisation) and PRINS (primed in situ DNA labelling), was combined with computer-aided chromosome measurements, to construct the first idiogram of the narrow-leafed lupin. The chromosomes are meta- or submetacentric; the mean absolute chromosome lengths range from 1.9 mum to 3.8 mum, and mean relative lengths from 1.6% to 3.3%. Data concerning linkage of resistance to 2 fungal pathogens as well as assignment of the second linkage group to the appropriate chromosome are given for the first time.
