In this study, chemical composition of eight native and non-native cultivars from”Ivanik”
nursery plantation - South-western part of Bulgaria, were investigated. High variability in
chemical composition among cultivars was found, corresponded to the high genetic
variability between cultivars. Cultivar I – 5/3, breaded from C. mollissima, produced nuts
with lowest moisture content. The highest moisture content was found for C. crenata x
sativa cultivars. Higher starch content showed cultivars, breaded from C. crenata. Cultivar
Zlatarevo had higher total sugar content, much higher than the average values reported by
the most of the researchers. Cultivars Marigoule and Hemus showed the lowest values in
crude protein, but highest were recorded for C. crenata cultivars. Lower in potassium and
phosphorous content were cultivars, breaded from C. mollissima and with higher content
were those, breaded from C. crenata. All of the cultivars are needed of mineral
supplementation in order to correct Ca:P imbalance.
