ABSTRACT
The aim of our studies was to evaluate the variability of bean production per plant in a collection of bush bean local landraces in order to establish if they can be used in
breeding programs. Biologic material consisted in a collection of 56 bean landraces
collected from western Romania and 6 cultivars. We assessed the number and weight of seeds per plant. The experiment was conducted in field conditions without irrigation. The collection proved to be less valuable for these characters. These genotypes are cultivated mostly for pods and are originating from hilly areas with cold and wet climate. Local landraces are inferior to bred cultivars. Landrace Sebis 1 stands out, producing over 40 seeds per plant, with also the highest seed weight (21.79 g). Beans productions above 15 g were observed only at 3 landraces: Voiteg, Paulean 2 and Vinga. The landraces studied are not adapted to conditions in the plains
