Abstract
Information on the utilization of fruit species in Bulgaria dates back to 4000 years ago.
The fruit growing in the country has developed significantly in the 17th century.
In many of the small settlements, especially in the mountain areas, old and local fruit cultivars and forms are still preserved.
The current study aimed to describe in details the fruit quality of some most appreciated by the population old and local pear genetic recourses.
For completing this objective, fruit size, fruit flesh firmness, total soluble solids content (°Brix), and skin colour of the cultivars ‘Mayska’, ‘Mehmedka’, ‘Eniseyka’ and five local forms found in Plovdiv and villages in the Karlovo region were measured. ‘Mehmedka’ had the largest fruits of 125.33 g with the highest TSS content (18 °Brix). The lowest fruit weight and TSS content were measured for the earliest ripening cv. ‘Mayska’. For evaluating the fruits’ chemical content analysis were performed.
The cultivar ‘Mehmedka’ had a significant amount of invert sugar in their composition (12.36%). The sucrose content in the fruits is low and varies from 0.19% in ‘Mayska’ to 2.64% in ‘Eniseyka’. Acids, which are a natural sugar balancer in fruits, range from 0.22 to 0.84%. Relatively higher acidity had the tree local forms VA 1 (0.84%), MN 1 (0.75%) and LT 1 (0.73%). The identified old cultivars and local genetic recourses could be a valuable addition for the fruit breeding.
Their location was mapped and planting material was produced from the forms threatened with extinction.
