During research expeditions in the Central Balkan Mountain region, trees of late-ripening (mid-October), rare local cultivars, and forms of apples with valuable pomological and biological qualities were marked. In 2021, all marked forms bore abundant fruit. The highest yield (280 kg per tree) was registered in 'Meka Shekerka’ cultivar (MS F1). The fruit weight was on average 59.50 g, obloid form, low percentage of dry matter (12%), a high percentage of total sugars (18%), and the highest glucoacidimetric coefficient. BF1 was distinguished by yields of 140-150 kg per tree, very good taste of the fruit (lowest acid content 0.27%), attractive appearance (green-yellow with a blush on the sunlit side), white fruit flesh, pleasant taste with a pronounced aroma of green apple, abundant waxy coating, with a mass of 86.17g and globose fruit shape. Our scientific data are compared with the information obtained from the local population on age, origin, fruitfulness, use, and distribution in the region.
