It’s been proceeded for early selectionsbased on correlations in order to create new varieties with high productivity and organoleptic qualities. Characteristicsand traits of the 36 varieties and hybrids of apricot studied, grouped according to the period of maturation, werestudied starting with the IPGRI descriptors used in Genus Prunus. The characteristics were followed: trunk crosssectionalarea (cm 2 ), fruit production (t/ha), the number of fruit tree branches unit length of thick branch and fruitbranch type specific for apricot. The resulting correlations between fruit production (t/ha) and the number of fruit treebranches unit length of thick branch R 2 =0,1084***. For series of data belonging to fruit production (t/ha) and numberof fructification branches (spur branches, short branches, long branches and mixt branches) the correlation coefficienthad 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 R 2 = 0524**.Key words: apricot, varieties, productivity, fructification branches, correlations.INTRODUCTIONThe creation of apricot varieties with differentfruit maturation periods, especially extra earlyand late maturation (Bassi D. and AudergonJ.M., 2006), has been a priority since 1980 toimprove the program in Romania. The markethad a demand for extra early apricots(Audergon J.M., 1995), until recently satisfiedby importing them from the Mediterraneancountries like Italy, France, Spain and Turkeyis a strong argument for the scientists involvedin the improvement of this species.MATERIALS AND METHODSThe biological material is represented by 36varieties and hybrids of apricot with differentfruit maturation periods: very early (ve), early(e), middle (m) and late (l).These were grouped according to the period ofmaturation and studied starting with the IPGRIdescriptors used in Genus Prunus.The characteristics were followed: trunk crosssectionalarea (cm 2 ), fruit production (t/ha), thenumber of fruit tree branches unit length ofthick branch and fruit branch type specific forapricot.241The trunk cross-sectional area was calculatedafter the formula TSA (cm 2 ) = D x d, in whichD = diameter of the trunk on the rows directionand d = diameter of the trunk perpendicular onthe row direction.Characteristics of fructification type is agenetic particularity and it shows thepredominating fructification of the varieties. 3trees were marked from each variety andhybrid, choosing and marking the thick branchin which the dynamically numbered andmeasurements of the fructification branches(Cociu V. and Oprea St., 1989). They werecounted and registered: number of fructificationbranches unit length of thick branch, number ofspur branches unit length of thick branch,number of short branches unit length of thickbranch, number of long branches unit length ofthick branch and number of mixt branches unitlength of thick branch.Fruit production was calculated from themedium production, cross-referred to thedensity of 625 trees per hectare (4 x 4m).For a more objective interpretation, the resultswere statistically processed using statisticalsoftware, obtaining the coefficient of variability
analysis of variance to express the variability inthe character analysis.RESULTS AND DISCUSSIONSTrunk cross-sectional area (cm 2 )The lower section of the trunk had thephenotypes: Andrei (m) with 180 cm 2 , 82.12.2BIV (e) and Valeria (ve) with 184 cm 2 andRares (ve) with less than 190 cm 2 . The mostphenotypes with over 250 cm 2 , resulted to be:Adina (l), Excelsior, Ilinca, Bucovina (m) andFavorit (l).Significant differences were provided for aprobability of error of up to 5% betweenmaturation groups, with limits ranging from189 cm 2 to 231 cm 2 (Figure 1). Variability tothe index of section of the trunk has a highvalue, expressed by the variability coefficientof 55,92%.Figure 1. Phenotype influence on cross-sectional area ofthe trunk based on the year of studyThe total number of fructification branches /linear meter of thick branchThe phenotype Ilinca (m) had the highestaverage number with 47 of fruiting branches.45 of fruiting branches had the phenotypes:Viorica (e), Nicusor (m) and Excelsior (m).With 44 of fruiting branches presented thephenotypes: Adina (l), Favorit (l) and Carmela(e) each with 43 of fruiting branches and Dacia(e) with 40 of fruiting branches. The coefficientof variability of the total number offructification branches/linear meter of thickbranch, expressed a medium-high value by thecoefficient of 21.81%.Number of spur branches / linear meter ofthick branchThe phenotypes with the bigest number of spurbranches were: Nicusor (m) – 27 branches,Valeria (ve), Viorica, Carmela (e) with 26branches, Dacia (e) and Rares (ve) with 25branches, Ilinca (m) – 24 branches, Alexandruand Andrei (m) each with 21.The variability of number spur branches /linearmeter of thick branch has a high valueexpressed by the coefficient of 71,57%.Number of short branches /linear meter ofthick branchThe phenotype 85.2.89 BIII (m) had the mostshort branches number/linear meter of thickbranch (over 22), followed by the phenotypes:Adina (l), 85.4.108 BIII (m), 85.3.100 BIII (m),82.28.62 BIV (m) and 82.12.7 BIV (l), withmedium between 15-20 short branches /linearmeter of thick branch. The variability of thenumber of short branches/linear meter of thickbranch had a high value, expressed by thecoefficient of 52,61%.Number of mixed branches /linear meter ofthick branchThe phenotypes with the most mixed branchesnumber were: 82.16.7 BIV (l) with 26 mixedbranches/linear meter of thick branch,Excelsior (m), 82.15.48 BIV (l), 82.32.9 BIV,82.7.65 BIV,Ilinca (m) and 82.4.41 BIV (l) between 20 and25 mixed branches/linear meter of thick branch.Groups of very early phenotypes do not bearfruit on the mixed branches.Significant differences were provided betweenthe late maturation group (15 branches), themedium (10) and the early (2 branches) (Figure2). The variability of the number of mixedbranches /linear meter of thick branch has ahigh value, expressed by the coefficient of102,05%.Figure 2.
