The breeding process of edible honeysuckle in Slovakia has been focused on the selection of large – fruited cultivars with regular fructification and a high content of polyphenolic compounds in combination with ascorbic acid. That is why our research was aimed at studying a collection of 22 clones of Lonicera kamtschatica (Sevast.) Pojark. Gerda/25 in terms of anthocyanins and ascorbic acid content in the conditions of Nitra in 2005–2007. Results of chemical analyses and their statistical evaluation pointed to a wide variation range of anthocyanins that was the most significant in 2007 (5.96–19.18 g per kg), followed by 2005 (6.45– 13.95 g per kg) and the lowest variability was in the characteristics for 2006 (5.86–10.82 g per kg). The variability of ascorbic acid content had the reverse order in 2006 (10.02–92.29 mg per 100 g) 2005 (24.15–67.98 mg per 100 g) 2007 (9.71–46.47 mg per 100 g). The content of ascorbic acid and anthocyanins was statistically significant depending on the year, while in terms of anthocyanins differences can be considered statistically significant between 2005–2007, 2006–2007, the difference between 2005–2006 was on the border of probability level a = 0.05. For ascorbic acid content statistically significant differences between years 2005–2006 and 2006–2007 were confirmed. The correlation between ascorbic acid and anthocyanins was very weak in a negative way in 2005 and in a positive way in 2006 and 2007. In respect of anthocyanins and ascorbic acid content clones KL-19 (12.21 g per kg, 48.77 mg per 100g) and KL-18 (11.8 g per kg, 56.11 mg per 100 g) seem to be the most perspective.
