| Abstract:
Over the 1989–1991 period a total of 75 peach genotypes were selected from the large number of indigenous populations of so called "domestic wild or vineyard peach" (Prunus persica ssp. vulgaris) by the researchers from different scientific institutions in Yugoslavia (Paunovic, 1992). Within the selected number of peach genotypes, 3,2% of them were susceptible to plum pox (Prunus virus 7), and 1.6% were highly resistant or tolerant, 2.7% of the selected peach genotypes showed extremely low susceptibility to Monilia laxa (Honey) and Monilia fructigena (Aderh and Rulh), whereas 24.0% were highly susceptible. Towards Sphaerotheca pannosa (Wallr) Lev, 4.0% was extremely low resistant, while the percentage of highly resistant was 22.0% of the peach genotypes. Pomological and genetic characteristics are: flower type: rosaceous-81.1% and campanulate-18.9%; petiole gland shape: reniform-67.9%, globose-30.2% and absent-1.9%; harvest maturity: extremely early-1.4%, extremely late-6.8%; productivity: low-4.0%, extremely high-53%; fruit size: extremely small-5.5%, large-19.2%; red skin colour: no red colour of the skin-48.6%, red colour mostly on the skin-2.7%; stone adherence: free stone-84.5%, clingstone-8.4%; flesh colour: white greenish-1.4%, yellow-orange-9.3%; flesh colour around the stone (red): no red colour-59.52% and full red-2.6%. The selected genotypes could be used for breeding purposes or directely as rootstocks (32.8%), fresh consumption (18.0%), processing (28.1%) (Paunovic, 1992). | |
