Abstrakt:	Abstract: Narrow‐leafed lupin (NLL) is a source of protein and fibre with exceptional functional properties useful for a variety of purposes. In adapted NLL germplasm selected for low alkaloid contents, the genetic base is narrow, thus limiting fast breeding progress. In an EMS‐based mutagenesis programme, we have treated 40,000 seeds of cv. ‘Boruta’ and obtained a variety of phenotypic mutant lines expressing novel growth types with altered plant height and/or branching. In 3‐year field trials at two locations, three of these lines exhibited significantly improved grain yield components compared to the cv. ‘Boruta’. Growth types of these promising lines were shown to be inherited in a monogenic recessive manner and should, thus, be easily fixable by breeding. [ABSTRACT FROM AUTHOR]
