Screening of eggplant genotypes with respect to anthocyanin content

Abstract

Seventeen eggplant lines were analysed for total anthocyanin content from the peel at the edible maturitystage of the fruits. For this, the trial crop was grown in the kharif season of 2018-2019 in RBD design with threereplications. The purple fruited lines had high anthocyanin content as compared to the green and white fruitedlines. Significant differences were observed among the lines for anthocyanin content irrespective of the degreeof purple skin colour. Pusa Shyamla had the highest anthocyanin content (139.04 mg/100g) followed by PusaPurple Round (51.33 mg/100g). The HPLC analysis identified cyanidin-3-O-glucoside, delphinidin-3-O-glucosideand delphinidin-3-rutinoside anthocyanins in brinjal lines. The highest delphinidin-3-O-glucoside was found inpurple fruited variety Pusa Upkar (7.44 mg/kg FW) and delphinidin 3-rutinoside in purple fruited line BR-40-7(18.83 mg/kg FW). The lines rich in anthocyanin content were identified in the present study and can be usedin the breeding programme in transferring the genes in high-yielding eggplant varieties.
