EVALUATION OF THE FRUITS QUALITY INDICATORS TO SOME BLACKBERRY GENOTYPES

Abstract

The fruits quality as a fresh product, must meet the higher quality standards, this is the primary criterion in decision-making of consumers purchase. Even if the fruits appearance is characterized by some properties like size, shape, color, the absence or the presence of the defects, however any factor affecting these traits is very important. Therefore the creation of the genotypes with high commercial impact is one of the main objectives of the breeding research. In order to achieve this objective, in 2000 were achieved 27 cross-combinations. From the hybrids obtained in the process of breeding, the most valuable genotypes were selected and multiplied. In the spring of 2004 these genotypes were planted in an experimental plot and standard cultural practices were applied. In the period 2010-2012 was carried out a study on the biometric quality standards of the fruit in order to identify the most valuable genotypes. Over the studied period the genotype E04/ 5-2 fruits recorded the highest size index value (22.81), the highest average fruit weight (8,22g) and a soluble solids content of 15.27%. The data were statistically processed with Duncan’s multiple range test (p≤0.05)
