Relationship between origin and nutrient content of Croatian common bean landraces
2018, 19 (3) p. 490-502
Common bean (Phaseolus vulgaris L.) is an important legume crop. In Croatia, many different common bean landraces are grown mostly on small farms and in kitchen gardens. The aim of this research was to determine and compare nutrient content of Croatian common bean landraces and to test the existence of the relationship between common bean nutrient content with origin of accessions. A total of 226 common bean accessions from all over Croatia were collected, grown in unreplicated field trial at the experimental field in Zagreb, harvested and analyzed for nutrient content. Results showed high nutrient content, but clear difference between Mesoamerican and Andean gene pool regards the nutrient profile of Croatian common bean landraces was not determined. Regardless of gene pool, the average nutrient content in dry weight of Croatian common bean landraces was in range: 3.13–3.92% N, 0.49–0.57% P, 1.38–1.66% K, 0.34–0.42% Ca, 0.17–0.20% Mg, 63.75–75.77 mg Fe∙kg-1, 13.55–19.94 mg Mn∙kg-1 and 24.98–29.32 mg Zn∙kg-1. Present research provides a solid basis for future breeding programs and improvement of common bean traits.
