The aim of the experiments was to evaluate a selection of faba bean (Vicia faba L.) var. minor varieties for further production improvement on the basis of their productivity and phenotype characteristics under the short season of the Northern European environmental conditions. The varieties evaluated were: Bauska, Favel, Fuego, Gloria, Jõgeva, Lielplatones, Priekulu and Priekulu viettejas. The highest and most stable average yield for 2015–2016 years was recorded in Bauska and Priekulu, with 3.77 and 3.64 t/ha, respectively. The incidence of chocolate spot and rust was in low to middling. Plant average height for 2015–2016 years was greatest in Bauska, Lielplatones and Priekulu vietejas, with 107.4, 110.7 and 110.0 cm, respectively. Resistance to lodging was best in Bauska and Fuego. From these yield and phenotype characteristics results we conclude that Lielplatones is the most suitable faba bean var. minor varieties for breeding in Northern European conditions, because of the following characteristics: middle yielding, quite high content of protein, very small seeds, low susceptibility to chocolate spot, good resistance to lodging. Thus almost every tested variety had some very good characteristics, which may also be valuable for the breeding of new varieties.
