摘要

Anthocyanin-rich maize offers considerable health benefits. A set of 48 sub-tropically adapted blue- and red- kernel maize inbreds were evaluated for anthocyanins in three different agro-ecological zones of India. Anthocyanins and its components were estimated using photo-diode array detector on reverse-phase ultra-high performance liquid chromatography. Significant genetic variation was observed for total anthocyanins (TA) (43.87-567.81 ppm). Cyanidin-3-glucoside (C3G: 56%), cyanidin 3-(6´´-malonylglucoside) (C3MG: 12%), cyanidin-3,5-diglucoside (C3DG: 12%), pelargonidin-3-glucoside (P3G: 18%), and peonidin-3-glucoside (Pn3G: 2%) were the major anthocyanins. TA in blue kernel inbreds ranged from 43.87 to 567.81 ppm, whereas the same in red kernel inbreds was 60.18-123.94 ppm. The blue-kernel inbreds were dominated by C3G (62% of TA) compared to red-kernel inbreds (C3G: 21%). The concentration of P3G (65%) and Pn3G (6%) was more in red-kernel inbreds over the blue-kernel genotypes (P3G: 10%, Pn3G: 2%). Among inbreds, MGU-CL-128, MGU-CL-111, MGU-CL-122 and, MGU-CL-125 were the most promising inbreds with > 400 ppm of TA. The cyanidin-based anthocyanins viz., C3G (r = 0.97), C3MG (r = 0.81) and C3DG (r = 0.88) showed positive association with TA. The identified promising inbreds can be used as donor parents in anthocyanin breeding programs that hold significance in nutritional security and industrial applications. This study offers a detailed assessment of anthocyanin diversity in sub-tropically adapted blue- and red-kernel maize inbreds, revealing distinct pigment profiles and identifying high-anthocyanin genotypes for potential usage in biofortification and industrial applications.
