To develop the potential of Lupinus angustifolius L. (narrow-leafed or blue lupin) for northern European conditions, we have conducted a germplasm improvement program based mainly on selection in different climatic conditions. A set of 50 accessions of narrow-leafed lupin was studied in Finland, Russia and Ukraine using a consistent protocol. Most of the variation in yield (56%) was due to environmental factors, less to the genotype (23%), and the genotype x environment interaction variance was moderate at 13%. The program has focused on the development of germplasm for the long days (18 h) and relatively low temperatures of southern and eastern Finland (latitude 60-62°N). The photoperiod reaction has been studied in more detail in four promising accessions and a breeding line Mut-1 was selected from Poland for crossing. This line demonstrated a stable vegetative period at different latitudes, and also had a long-day photoperiodic reaction. Subsequent studies showed that Mut -1 demonstrated a long-day photoperiodic reaction only at or above 16°C. From this breeding program, two new cultivars, temporarily named Fin-1 and Fin-3, have been developed. They have restricted branching, a growing season of  85-115 days, seed yields up to 2.3 t/ha, and seed protein content of 36-42 %. The next step is comparative yield trials with established cultivars.
