Developing Functional and Antioxidant-Rich Table Grape Cultivars by Crossing Alicante Bouschet x Alphonse Lavallee

Abstract

Recently, red and black colored grape cultivars are getting more popular due to anthocyanins in the skin and flesh of berries which are called teinturier grapes. Anthocyanins are a group of polyphenolics which can prevent many diseases by inhibiting or delaying the oxidative damage. But there is no a teinturier table grape cultivar in Turkey, but there are some teinturier wine grape cultivars such as Alicante Bouschet. Main goal of this study was to obtain tenturier genotypes by crossing of Alphonse Lavallee and Alicante Bouschet grape cultivars and to compare anthocyanin coloration of cotyledon and true leaves for early selection for tenturier candidates. Anthocyanin coloration was visually observed in cotyledon leaves. Amount of anthocyanin were determined in true leaves by spectrophotometrically disc method. Cotyledon and true leaves of most genotypes had the green color and there were parallelism between both leaves. The amount of anthocyanin of true leaves weredetermined as 50.21 mg/kg in green colored leaves and 131.51 mg kg-1 in dark colored leaves.
