Current requirements of the species Prunus armeniaca in terms of creating new varieties require a conducted extensive research in the apricot breeding program in the south-eastern of Romania. It’s been proceeded for early selections based on correlations in order to create new varieties with high productivity and organoleptic qualities. Characteristics and traits of the 36 varieties and hybrids of apricot studied, grouped according to the period of maturation, were studied starting with the IPGRI descriptors used in Genus Prunus. The characteristics were followed: trunk crosssectional area (cm2), fruit production (t/ha), the number of fruit tree branches unit length of thick branch and fruit branch type specific for apricot. The resulting correlations between fruit production (t/ha) and the number of fruit tree branches unit length of thick branch R2=0,1084***. For series of data belonging to fruit production (t/ha) and number of fructification branches (spur branches, short branches, long branches and mixt branches) the correlation coefficient had a lowered value, between 0,0007 si 0,0524**. So, this resulted in a somewhat correlation between fruit production (t/ha) and number of spur branches to the unit length of thick branch R2= 0524**.
