Effect of genotype and environment on the chemical composition of raspberry fruits

Four raspberry cultivars were grown at two different latitudes namely in Geisenheim (DE, 49°60’N; 7°57’E) and in Kapp (NO, 60°42’N; 10°52’E) to investigate the impact of these growing sites on primary and secondary fruit chemical ingredients in the 2017 season.
Fruits were harvested at two picking dates each with three field replications.
Contents of °Brix, glucose, fructose, sucrose, organic acids, ascorbic acid, polyols, total polyphenols, and anthocyanins were analyzed in the fruits.
The geographic growing sites, which in this case is more than10 latitudes between HGU in Germany and NIBIO in Norway, has partly no, partly significant effects on the primary and secondary ingredients of the investigated raspberry cultivars.
In respect to the created data set, temperatures shortly before or at the picking dates were not considered.
It may be expected that temperatures at harvest have an effect on the fruit ingredients and therefore on a further classification of the samples.
