Lupinus angustifolius L. is the most important cultivated lupin species in Central Europa, especially
in Germany. Currently the only breeding program in Germany is located in North-East Germany
at Saatzucht Steinach. Yield parameters of 50 varieties and breeding lines (eight with restricted
branching and 42 with normal branching) of narrow-leafed lupin (Lupinus angustifolius L.) were
measured in Mecklenburg-Pomerania over three years at three locations to demonstrate the effect
of locations (l), years (y), genotypes (g), and genotype x environment interaction on yield and
crude protein content. The locations, years, genotypes and the genotype x environment were
clearly significant for each parameter. The trials demonstrate, that environment has a greater
influence on yield (significant at < P = 1%). For grain yield, the strong interaction between site
and year was caused by the extreme environment of Bornhof. The highest yield was found in
2011 at the site Groß Lüsewitz. Yield was more affected by site than by year. The crude protein
content was also significantly affected by site and year. Between the year 2010 and 2012 less
differences were found among the sites. Yield was negatively correlated with crude protein
content. The differences in crude protein yield reflect the differences in yield indicating the
stronger impact of grain yield than of protein content.
