 Abstract: In Romania, normally, the bean (Phaseolus vulgaris L.) is considered a self-pollinated plant. Vegetable Research and Development Station (VRDS.) Buzău possess a bean gerplasm collection presenting over 450 accessions. In 2020, a high percentage of allogamy was found in cultivated accessions. This paper presents the study of two climbing bean accessions seeds sown. For each accession sown, there were taken into study nine new biotypes harvested. The seeds sown represented the control variant for the analysis of the harvested biotypes. The seeds were evaluated in what it concerns quantitative (100 seed weight, length, thickness and width) and qualitative characteristics (seed color and shape). The mean weight of 100 seeds at V1 was 39.41g (higher value than the control variant – 36.38g) and at V2 the mean weight (43.81g) was smaller than control variant (46.95g). The variability coefficient for this parameter had a medium value (V1 11.42% and V2 16.72%), the other analyzed parameters had a small variability. The main colors of the control seeds were brown (V1 – medium and V2 –dark). At V1 there were white seeds (1.5.), and at V2 khaki (2.9.)
