STUDY OF PHENOTYPIC VARIABILITY IN PLUM HYBRID POPULATIONS FROM CULTIVAR ‘TULEU GRAS’

In Romania, the plum is a major species owing to its large grown acreage, production and various ways of marketing.
The Romanian plum breeding program started in the 50’s.
The objectives of this program are similar to the ones from other countries, aiming at: productivity, fruit quality and disease resistance, Plum Pox Virus, particularly.
In the frame of this program cultivar ‘Tuleu gras’ was widely used in crosses as a parent due to its possible genetic plasticity.
Its progeny is extremely various for blooming, fruit size, shape and skin colour, as well as susceptibility to Plum Pox Virus.
Out from 500 hybrids 15 elite plants were selected for further evaluation at Pitesti, Romania to detect their suitability to climate conditions.
Five of them have been selected as cultivar candidates.
High diversity of cultivar ‘Tuleu gras’ progeny is a valuable plum breeding sources for southern part of the country, to develop cultivars with high fruit quality and tolerance to Sharka.
The aim of this paper was to evaluate the variability of cultivar ‘Tuleu gras’ progeny using phenotypical character¬ization.
