Abstract



Introduction: Climatic conditions are favourable for cultivation of this species throughout our country. Pea entered Europe in its southeast regions and progressed into its interior via Danube.( Ljuština, Marija, 2010) Concerns for growing this species at V.R.D.S.Buzau existed since the establishment (1957). The assortment of varieties has been recently enriched with a new patented variety named Getica.  Pea (Pisum sativum L.) was the original model organism used in Mendel’s discovery (1866) of the laws of inheritance, making it the foundation of modern plant genetics. (Smýkal, 2012). Pulses, including peas, have long been important components of the human diet due to their content of starch, protein and other nutrients. (Wendy J. Dahl, 2011).

Aims: Assortment enriching with new valuable varieties in this species, with high yield capacity and high quality, with different periods of maturation in order to reschedule over a long period of time.

Materials and Methods: Researches started with collecting germplasm in this species which currently contains 31 genotypes. As genotype control variant in evaluating and sorting the material used for variety improvement was used the well-known variety Getica. After evaluating this collection four genotypes were retained. Breeding method used was especially recurrent individual selection.

Results: The researches finalised with the achievement of four new accessions which show different maturity ages; the earliest was L1 that reached technical maturity on June 1 and the late was L4 that reached technical maturity in June 25. The control variant matured in June 5. In terms of plant height, the most vigorous was L4 with 105 cm height and L3 showed a dwarf port with an average height of 56 cm.

Conclusion: It has conducted and evaluated a valuable germplasm collection that can be harnessed to improve future research work, also were obtained four new varieties with distinct characteristics, different ripening periods that will  be proposed for patenting. The results received after promoting new creations among farmers by distributing promotional biological material (seeds) are very positive.
