The comparison of the commercial grapevine varieties for their nutritional and marketing properties

• The biochemical comparison of the 12 important genotypes of the Iranian grapevines. • Plant anthocyanin and antioxidant activities were significantly correlated. • Kashmar2 and Flame had the highest antioxidant activities and so are healthier. • The most nutritious, and marketable genotypes of grapevine genotypes, indicated. • The results can be used for breeding, commercialization and export purposes. One important issue determining fruit marketing, is fruit nutritional properties. The 12 most important varieties of Iranian grapevine, planted in Chaharmahal & Bakhtiari province, Iran, were investigated for their biochemical properties as the objective of the research. Plant biochemical properties of soluble solid content (SSC), carotenoids (Car), total phenol (Phenol), titratable acidity (TitA), acidity (pH), anthocyanin (Ant), antioxidant activity (Anti), fruit fresh (FW) and dry weights (DW), dry weight percentage (DWp), fruit juice weight (WW), fruit juice density (ED), and fruit volume (FV) and density (FD) were determined. The varieties with the highest measured parameters were: Kashmar2 (Phenol, Anti, FW and ED), Flame (TSS, Ant and Anti), Rish Baba (TitA, pH, and FV), Shahoroudi (Car and FD), Seedless Red (TitA and Ant), Asgari Daei Nasrollah (pH and ED), Kashmar1 (FV and FD), Asgari (DW and DWp). The following correlations were significant: Car and Ant (-0.53), Phenol and Ant (-0.54) and Anti (-076), Ant and Anti (0.90), DW and DWp (0.91), WW and Ed (0.54), Ed and FD (-0.50), FV and FD (-0.70). Kashmar2 and Flame had the highest antioxidant activities and so are healthier. The most nutritious, tasty and marketable varieties of grapevine genotypes, suitable for export may be selected.
