Five transgressive variants derived from a cross between the wild rice, Oryza rufipogon Griff and a high yielding Malaysian rice cultivar O. sativa L. indica cv. MR219 were evaluated for red pericarp stability, grain yield potential and resistance to blast disease. The experiment was conducted at a single location over two seasons. Grain yield was significantly higher (15%) than MR219 for variant G33 (R14-3-66-4-B-B) which also possessed the desired physico-chemical properties of grain with high antioxidant activity (Ferric Reducing Ability of Plasma = 107.72 molFeSO4/g and Total Phenolic Content = 0.49 mg GAE/g), low glycemic index (GI =51) and low insulin index (II = 39). The same variant was resistant to blast disease and the red pericarp colour was stable. The transgressive variant G33 is recommended for cultivar development as a specialty rice.
