EVALUATION OF LOCAL PLUM VARIETIES (PRUNUS DOMESTICA L.) FROM THE ROMANIAN NATIONAL COLLECTION

In Romania, plum holds the first place in the national fruit holdings as acreage and number of trees planted.
One of the most important conditions for reaching the objectives in the plum-breeding program is the availability of a rich germplasm collection.
The National Plum Collection (NPC) located at the Research Institute for Fruit Growing Pitesti – Maracineni (RIFG), holds 566 accessions from which 183 genotypes are of Romanian origin.
This rich native germplasm collection has been evaluated regarding tolerance to PPV, susceptibility to Monilia sp., precocity, blooming period, fruit size, content in soluble solids, yielding capacity, tree vigour, according to the numerical scale of IBPGR descriptors used in Genres Project 61 of ”Prunus Data Base”. This study shows that the numerous genotypes existing in the NPC offer enough initial material to achieve the objectives of the Romanian plum breeding program (e.g. ‘Grase de Becs’, ‘Grase de Pesteana’, and ‘Ciorasti de Mehedinti’ for tolerance to PPV; ‘Tita’, ‘Pitestean’, ‘Carpatin’, ‘Record’, and ‘Roman’ for large fruit; ‘Centenar’, ‘Grase de Becs’, and ‘Grase de Pesteana’ for high and constant productivity; etc.).
