RESEARCH ON PHENOTYPIC AND GENOTYPIC EXPRESIVITY OF BEAN VARIETIES OBTAINED AT VEGETABLE RESEARCH DEVELOPMENT STATION BUZAU

The pedo-climatic conditions of Romania are favorable for bean cultivation, one of the reasons that. in past. field beans used to occupy large areas in Romania. Although it is a plant that can offer high economic profit to the growers and is a good precursor for other vegetable plants due to nitrogen accumulation, the field bean it's no longer sought and used at its maximum potential as a crop plant. Since 1996, Vegetable Research Development Station (V.R.D.S.) Buzau has been revive the researches in beans, realizing until now a valuable collection of germplasm, grouped by types of growth and directions of use. For this research, three stable genotypes of field bean group were studied The genotypes showed distinct variability in plant height, the highest value being 61.83 cm (A3) and the smallest value being 38.8 cm (A1). Slightly differences were also registered by the number of pods per plant. The studies have been completed with the registration of the genotype A2 for patenting and approval under the name of "Doina" and the other two genotypes will be proposed for approval.
