Relationship between phenolic compounds and antioxidant activity in berries and leaves of raspberry genotypes and their genotyping using SSR markers
Researchers from the Forest Biotechnology Group of the FIBCh together with colleagues from other institutes studied the content of total phenols, flavonoids and anthocyanins, their relationship with the antioxidant activity of berries and leaves of various raspberry cultivars of Russian and foreign origin, as well as new breeding lines. An optimal method for the analysis of antioxidant activity of raspberry was determined, breeding lines superior to standard cultivars were identified, and phenological phases for the maximum bioactive value of raspberry plants were established. In addition, for the first time, the relationship between the chemical diversity of plant cultivars and genetic markers specific for a particular metabolic pathway was studied. The strong correlation between biochemical and genetic data makes it possible to use these markers in the selection for improving nutritional properties, as well as to study the mechanisms of flower and fruit color formation.
