Abstract
The phenotypic response of plum cultivar ‘Stanley’ in relation to the main production and technological traits was studied at four localities in Serbia (Prokuplje, Kuršumlija, Aleksandrovac, and Osečina) during the two-year period (2020-2021). Differences between localities and years were found in the data on climatic conditions.
For the period from April to August, the locality of Prokuplje had the highest average temperature and the lowest total precipitation, while the locality of Kuršumlija had the lowest average temperature and the locality of Aleksandrovac had the highest total precipitation.
Most traits of cultivar ‘Stanley’ varied significantly in different localities.
The highest average yield (20 t ha‑1), fruit weight (43.0 g), fruit length (51.2 mm), fruit width (38.7 mm), fruit thickness (38.0 mm), and flesh rate (95%) were found at the Osečina locality, while the highest soluble solids (19.6%), total sugar (13.8%), invert sugar (12.3%) and the ratio between total sugar content and total acid content – TSC/TAC (21.4) were found at the Kuršumlija locality.
In order to overview the data for similarities and dissimilarities, PCA was applied to take into account all studied factors and all characteristics.
This analysis shows that the cultivar ‘Stanley’ had differences in the stability of the traits by year in the studied localities.
The lowest stability was observed in the locality Aleksandrovac, followed by the locality Kuršumlija, while the highest stability was observed in the localities Osečina and Prokuplje.
Osečina locality can be recommended as the best location for growing this cultivar.
