چکیده :

There is a great diversity of prune tree in Iran's indigenous germplasm. This study was conducted to evaluate the tree and fruit characteristics of new prune cultivars named ‘Golab’, ‘Shahriar’, and ‘Safa’, along with ‘Alborz’, ‘Malayer’, ‘Qomi’, and ‘Siah’ in Kashan, Iran, during the years 2021 to 2024. Trees were planted in a randomized complete block design with three replications and four trees in each replication. The highest trunk diameter was observed in ‘Malayer’ with an average of 46.29 mm and the lowest in ‘Shahriar’ and ‘Golab’. ‘Malayer’ had 29.95% more trunk diameter than ‘Golab’. In contrast, crown width in ‘Alborz’ showed the highest average. The lowest crown width was observed in ‘Siah’. The difference in average crown width between these two cultivars was 31.05 cm. The tallest tree belonged to ‘Shahriar’ and then ‘Malayer’. ‘Golab’, ‘Qomi’, and ‘Alborz’ had the lowest tree height. ‘Shahriar’ had 28.44% higher height than ‘Golab’. The lowest annual growth was recorded in ‘Siah’. Other cultivars did not show significant differences in the values of this trait. The range of internode length varied between 7.90 mm in ‘Malayer’ and 13.10 mm in ‘Qomi’. ‘Qomi’ showed the highest leaf length and width, while the lowest leaf length and width were observed in ‘Golab’. Yield efficiency in ‘Alborz’, ‘Golab’, and ‘Shahriar’ was higher than other cultivars with averages of 3.35, 2.73, and 2.71 kg/cm2, respectively in 2023. ‘Malayer’ had the lowest yield efficiency and yield per tree. According to the obtained results, ‘Alborz’, ‘Shahriar’, ‘Golab’, and ‘Safa’ are recommended for cultivation in orchards and can be used as first fruit.
