Genetic control of fruit pigmentation in raspberries is a complex phenomenon. Pigmentation itself is one of the most important traits where a range of colour patterns from deep purple to yellow exists. Anthocyanins and carotenoids are known to be the main pigments in raspberries; however colour of fruits is mainly considered due to varying anthocyanin contents (1). These compounds have been described to have potential health beneficial effects against cancer, aging, inflammation and neuro-degenerative diseases (2). Aside from the health benefits, anthocyanins play basic role as an indicator of fruit quality and consumer acceptance. The role of anthocyanins in planta is not known exactly, however protective role against biotic and abiotic stresses has been discussed. Apparently it seems that carotenoids are responsible for colour in yellow raspberries, due to the loss of masking effect of anthocyanins (3). Thus, in yellow raspberries there might be a block of anthocyanin biosynthesis and that can be the possible reason behind the yellow pigmentation.
