Abstract
Several Romanian cultivars were developed and continue to be grown due to their resistance to biotic and abiotic stresses, as well as their high fruit quality.
The main aim of this research was to investigate some promising plum cultivars to compare their marketing value to that of the currently cultivated ones.
Therefore, in this research, morphological characteristics and various fruit quality traits were investigated in three different non-native plum cultivars as follows: Prunus domestica ‘Königin Victoria’, Prunus domestica ‘Presenta’, and Prunus domestica ‘President’. The selected genotypes revealed significant differences in all the measured characteristics.
Fruit length ranged from 31.88 to 59.72 mm; ten-fruit weight ranged from 18.19 to 48.06 g.
Leaf length ranged from 9.27 to 11.25 mm; leaf width from 4.87 to 6.04 mm.
Fruit weight was positively correlated with fruit length, fruit width, fruit pulp thickness, fruit stalk length, stone length, stone width, stone weight, and also with leaf parameters such as leaf length and leaf width.
Regarding fruit quality, fruit firmness varied from 1.25 to 2.86 kg cm-2, the total soluble solids’ content ranged from 15.20 to 19.30%, while the moisture content was the highest in the President genotype (82.13%). Titratable acidity varied from 0.60 to 1.01%. The results of principal component analysis (PCA) and multivariate analyses, performed using the mean values of all morphological and chemical parameters, highlighted interesting relationships and variations among the genotypes.
