THE COMPARISON OF PHENOLIC COMPOUNDS CONTENT, ANTIOXIDANT CAPACITY AND MOLECULAR ANALYSIS OF SOME SELECTED TURKISH PEAR GENOTYPES

Abstract

The current study was focused on molecular analysis using internal cpDNA trnL intron sequence, antioxidant activity, total phenolics and flavonoid contents of fifteen pyrus genotypes. Quite variations were determined in biochemical characteristics and molecular systematic analysis of genotypes evaluated. Y. Karcin genotype was detected as the best graded genotype based on the high contents of the total phenolic (7,92 mg GAE/g) and total flavonoid (4,50 mg RE/g) content. The obtained results showed that, genotypes could be categorized of six main clades with robust bootstrap values, which might be useful to improve genetic diversity among genotypes for breeding.
