| Abstract:
Fruit from 12 black currant cultivars was harvested five times during fruit maturation and variability in fruit quality attributes was studied. Vitamin C content of the Scottish ‘S1’ and ‘S3’ was superior, followed by ‘S4’ and ‘S5’. Fruit skin colour of ‘Ben Nevis’ and ‘S4’ were best at the third harvest, but ‘S3’ expressed good fruit colour in the fourth harvest. Fruit acidity of ‘S1’, ‘Ben Lomond’ and ‘Ben Nevis’ was higher than other cultivars. in the highest sugar contents were found in ‘Brodrop’, ‘Risager’, ‘Fertodi’, ‘S3’, ‘S4’, ‘S2’ and ‘S1’. Vitamin C content decreased from the 1st to the 5th harvest. Acidity and color values were highest appeared in the 3rd or 4th harvest; while the highest sugar content was typically found in the 2nd, 3rd, 4th or 5th. Harvest varying among cultivars. The optimum time for harvesting fruit for processing was 4 to 8 d after 90% fruits turned black, differed according to cultivar. | |
