Abstract
The mountains of Kazakhstan are a center of biodiversity for many important fruit and nut tree species, including wild apple (Malus sieversii (Ledeb.) M. Roem.). The value of the wild apple gene pool consists of a commercially valuable characteristic such as fruits with high bioactive substances, and diverse colors and flavors, as well as drought, frost, pest, and disease tolerance.
This study was conducted to select valuable genotypes of M. sieversii from the Almaty bioreserve.
Phenological observations were conducted during two years (2022, 2023) in wild apple populations.
Pomological parameters (weight, fruit shape, fruit ground color, fruit overcolor, greasiness of skin, fruit stalk length, flesh color, flesh firmness, flesh flavor, fruit ribbing), chemical parameters (soluble solids, titratable acidity, water-soluble pectin, water-insoluble pectin, total pectin, water-soluble pectin/water-insoluble pectin ratio, total sugar, catechin, leucoanthocyanidin) were evaluated.
In the bioreserve wild apples exhibited a wide variation on most of the fruit and tree morphological and biochemical characteristics.
Our results showed that these valuable apple forms may also be effectively introduced into ex-situ and in breeding programs to produce new cultivars with improved chemical composition.
