Narrow-leafed lupin (Lupinus angustifolius) represents a resource of proteins with high nutritional
value for humans. To make use of this potential for a broad range of food applications the
regional network 'PlantsProFood' was established in the Northern part of Germany. Lupins shall
be promoted as a protein resource for food purposes, like ice cream, sausages, bakery products or
pasta. The network, consisting of four research institutions and ten local companies, aims at
processing the value chain from the development of (I) new varieties, (II) new processing
approaches towards (III) innovative and healthy food. Key for these efforts are high and stable
kernel yields of narrow-leafed lupins. This may be accomplished by plant breeding provided that
sufficient genetic variability for relevant traits is available. To broaden the genetic variability of
advanced lupin breeding materials an EMS (ethyl methanesulfonate) treatment of cv. ‘Boruta’ was
performed. Phenotypes with a striking novel growth type, like vigorous growth or high branching
compared to the wildtype ‘Boruta’, were identified and devised to homozygous and stable
M lines. The yield potential of the M lines was estimated under field conditions and revealed in
some cases significantly increased kernel yields. For genetic analyses, crosses of the respective
M lines with gene bank accessions as well as with the wildtype were performed. Segregation
analysis of F2 populations indicated a monogenic-recessive inheritance of novel growth types.
Promising M lines are going to be subjected to an analysis of differentially expressed cDNA
between mutant lines and the wildtype to develop molecular markers for the mutant traits.
