Abstract:
One of the main objectives concerning the research activity of the Vegetable Research and Development Station (VRDS) Buzau collective is represented by biodiversity preservation of vegetables species and also the valorization of the germplasm collection by creating new cultivars. This paper presents the main characteristics of 10 local populations of dwarf bean (Phaseolus vulgaris L. convar. nanus) selected from this species germplasm collection that contains over 150 accessions. In 2014 weather conditions, the most productive variant was V2 having 291.57 g plant‑1. At the same variant maximum values were registered regarding thickness (1.2 cm), weight (13.25 g) and the proportion between pods thickness and width (1.14). The pods obtained from V2 variant are green having a circular or eight shaped cross section and it does not form stringiness on ventral suture at physiological maturity. In what concerns the V9 variant on the one hand the highest value regarding the number of pods plant‑1 (27.33) and the number of seeds pod‑1 (7) were registered, and on the other hand the lowest values regarding width (0.84 cm), thickness (0.73 cm) and pods weight (6.83 g). These characteristics confer an increased commercial value to the V9 variant. After 52 days from seeding V10 had pods with 12 cm length, and at V7 the pods measured 9 cm. Due to the special characteristics (earliness, productivity, distinctiveness, uniformity, stability) a variant has been homologated (V9 – ‘Clarisa’), another variant is in process of homologation (V2 – ‘Cristiana’), and others will be homologated as new cultivars.
