THE COMPARISON OF TOTAL PHENOLIC CONTENT, ANTIOXIDANT CAPACITY AND MOLECULAR ANALYSIS OF SOME SELECTED TURKISH APPLE (MALUS SPP.) GENOTYPES

Abstract

In the present study, eight apple genotypes were analyzed using internal cpDNA trnL intron sequence. Furthermore, these genotypes species were evaluated for their antioxidant activity, total phenolic and flavonoid contents. Genotypes in question show quite a variation in biochemical characteristics and molecular systematic analysis. One of the genotypes Helesan was the best graded genotype based on the high content of the total phenolic (12,21 +/- 1,25) and total flavonoid (7,98 +/- 0,26) content. As a result of the molecular analysis, which is one of the main aims of the study, genotypes are comprised of three main clades with robust bootstrap (95) value. It was concluded that these genotypes could be useful to improve genetic diversity among genotypes for breeding.
