FABIANE, KELI CRISTINA et al. SELECTION OF PEACH GENOTYPES FOR BIOCHEMICAL FRUIT QUALITY CHARACTERIZATION. Rev. Bras. Frutic. [online]. 2017, vol.39, n.4, e-669.  Epub 27-Nov-2017. ISSN 0100-2945.  http://dx.doi.org/10.1590/0100-29452017669.

Peach is much appreciated by consumers and its popularity is mainly related with organoleptic characteristics. However, with emergence of concepts of functional foods (health promoters), there is high interest to study and to quantify the biochemical components of fruits. The aim of this work was to perform the biochemical characterization of peach genotypes, evaluating the genetic diversity and selecting those with desirable biochemical qualities for use as parents in future breeding programs. The experiment was carried out at the Laboratory of Plant Physiology - UTFPR - Campus of Dois Vizinhos, PR (Brazil), with fruits from 26 and 29 peach genotypes (Prunus persica) in the 2009/2010 and 2010/2011 crop years, respectively. The experimental design was entirely randomized, considering each genotype as treatment, using four replicates and four fruits per plot. Total and reducing sugars, total proteins, amino acids, total phenols, anthocyanins, flavonoids and phenylalanine ammonia-lyase enzyme activity (PAL) in fruits were evaluated. According to the results of two crop years, ‘Cascata 967’, ‘Conserva 985’, ‘Kampai’, ‘Tropic Snow’ and ‘Cascata 1055’ were selected as those with the highest levels of these compounds.
