Abstract
The apple (Malus domestica L.) is a relatively old species, thought to have been domesticated 4000 years ago.
It is one of the most profitable fruit crops, characterized by adaptability to different soils and climatic conditions, high yield, good storage and transportability.
In Bulgaria, apple cultivation has a long history and diverse cultivars are found in the country.
The current study describes the fruit quality of some valuable old and local genetic resources the cultivars Kantarka, Chervena Shekerka, Ayvaniya, Seedling YM found in the region of Tryavna and a random mutation of the cultivar Melrose which has been propagated and grown in the area of Han Krum village.
For this study, fruit size, fruit flesh firmness, total soluble solids content (°Brix), skin and flesh colour were measured.
For evaluating the fruits nutritional value, chemical and sensory analyses were performed.
The cultivar Ayvaniya had the highest total sugars (17.12%) and low total acids (0.29%) content. Ayvaniya also had the firmest fruit flesh 15.3 kg cm‑2 followed by Kantarka 13.6 kg cm‑2. These two cultivars fruits could be stored for a very long period.
The largest fruits with an average weight of 195.76 g and the highest TSS content were measured for the mutation of Melrose(18 °Brix). There were significant differences in the colour parameters L*, a*, b*, chroma, and hue between the different specimens.
All fruits are suitable for fresh consumption and preparation of traditional foods.
The identified old cultivars and local genetic resources could be a valuable addition to fruit breeding and/or organic fruit production.
Their location was mapped in order to aid their conservation in their natural habitats.
