Genetic variability and GxE interactions for total polyphenol content and antioxidant activity in white and red sorghums (Sorghum bicolor)

Sorghum has unique advantage in terms of its climate resilience and its grain composition with beneficial bioactive compounds. It is a very good source of bioactive compounds such as polyphenols and antioxidants. Breeding efforts for end‐use identity‐specific genotypes are required for increased profitability to the farmers. In this study, total polyphenol content (TPC) and free radical scavenging activity (FRSA) were estimated in 60 genotypes,...
